We've mow introduced our direct 

response forms, which allow Internet 

explorers to request intormation 

online. 

Advertisers get specific information, 

such 

as names, addresses and job titles, 

about inquirers, much as they would 

from people who fill out "bingo card" 

forms in print magazines. 

Like everyone 

else on the Internet, 

we're learning to use this new medium as 

we go along. Some important facts we've 

discovered so far are these. 

l, While the Internet doesn't make for 

a "paperless" office, it can radically 

reduce the amount of paper (and the

expense of printing) you incur to reach I 

your customers. The print bill alone for 

even a simple one- or two-page brochure 

can run to thousands of dollars even 

before you mail it. The same information 

disseminated on the Internet costs the 

amount of time it takes to generate the 

copy and get it up on line. And you have 

no mailing costs at all. 

2. The Internet is an infinitely flexible

3. The Internet can put you in touch 

with people you never dreamed would be

4. The people who use the Internet 

most right now are what marketers call 

"early adapters .." They like new technology, 

and they're eager to use it This attitude 

doesn't just apply to the Internet, 

They're just as interested in your newest 

products and services. They're 

of 

the kind 

of potential buyers you want to attract. 

As late as this summer,

success of our own Internet ventures has 

convinced me that as time goes on. more

an advantage over the competition.

as the secretariat for work on 

international gear standards. 

Workin.g through ANSI, the 

American National Standards 

Institute, it is responsible for 

processi ng documents as. 

they are developed. 

It also 

oversees. and arranges the 

various committee meetings, 

organizes ballots, supervises

distributes report of meetings,

Fig. 1 shows the relationship

Iy sotidy, Different company 

cover rating nomenclature, 

tooling and geometry, while 

AGMA's 58 standards also 

cover materials, enclosed 

drives, lubrication and other 

i s-ues. 

At the arne time, AGMA 

closely evaluates ISO gear 

standards development aad 

decides whether to incorporate 

its work into AGMA 

standard . It also sends delegates 

to ISO standard meetings 

to ensure that the U.S. 

has input into [SO standards 

development. 

According to AGMA 

Technical. D .•rector, 8H1 

Bradley, the goal of AGMA 

and ISO is to have good 

and national interests, various international standards that 

interpretations and under- 

everyone can use. The 

standings about what is 

important, differing personalities 

and agendas on the part of 

the delegates, all have to be 

factored into the equation .. 

An Ever-Receding Horizon 

[n truth, developing all 

universal gear standards may 

not be posslbte, at least in the 

foreseeable future. For example, 

until U.S. gear buyers 

accept metric units, if they 

ever do, two sets. of measurements 

will be used. 

AGMA continues to. develop 

its own standards far lise 

in the U.S. Us goal is to harmonize 

its standards with 

those of [SO, but at Ute same 

time, parallel development

has standards regarding some 

issues that ISO does not 

cover. ISO's 18 standards expectations. 

approach to this goal is an 

incremental one. Standard by 

seendard and meeting by 

meeting, AGMA and the 

other national standardsmaking 

organizations are 

working to bring their various 

standards closer and 

closer together. 

Consensus 

According 

by Compromise 

to. Bradley, 

some of Ute issues that make 

international standards development 

an exercise in the 

tine art of compromise are the 

varying formulas used for 

detennining gear performance 

and design, differences in 

understanding whatlhese formulas

Takethe case of developing

example. There are a number

All, these issues-and similar 

ones for every standardhave 

to be hammered out 

One of the most obviou 

wants--and 

needs to have--

But it's nnt enough to COIIvert. 

measurements from one 

system to the other. ISO 

would prefer to have standards 

in "hard" metric; that 

is, developed in metric from 

the ground up. Such standards 

for gears are easier to 

work wilh if IlooiWng is 

already set up in metric 

mcrements. 

On 'the other hand,. many 

U.S. companies are still Of1-

incites and feet, and it does 

not seem likely that the U.S.

measurement systems for 

some time to come. 

Anollter important difference 

that affects the way 

standards development 

shakes out. is Lile manufacturing 

orrentation of AGMA 

and other U.S. standards. 

"Standards development 

should be a market-driven 

process. There should be a 

market need for a given. tanda:rd 

before it's developed," 

says Bill Bradley. "Standards 

are no good unless they are 

usable in aeontract." 

AGMA' tandards tend to

lagging behind the "Slate

The less litigious nature 

of European countries makes 

that language unnecessary in 

[sO standards. 

Corporate & National! 

mter,esCs 

AOMA ha ,long been 

encouraging manufacturers to 

get more involved in standards 

development by sending 

delegates to standards 

committee meetings, "They 

should be involved," says 

Bradley, "because they're the 

ones who know what the 

markets have been asking for. 

They have the fieldexperience 

to say what's realistic." 

But thi involvement can 

impede compromise .. Obviously, 

individual companies 

have specific interests they 

want protected. However, as 

time goes on. and American 

manufacturers become more 

globally oriented. the need 

f'of compromise becomes 

more apparent and looking 

beyond narrow self-interest 

becomes easier. 

The ame is true of various 

national interests. The 

w.ay standards are written 

can ,intentionally or not, 

favor practices in one COUllII)' 

over those of another. Overcoming 

this national interest 

in the push for a. common 

benefit is one more element 

that has to be accommodated 

in the process. 

Perbaps swprisingly, this 

obstacle is not as big as it 

might be. "There's not as 

much nationalism or company 

protecti .onism as you 

might think," ays Bradjey, 

"People on Ute committees

However, these standards 

have caused a good deal. of 

controversy. Many people 

both in !he U.S. and .Europe 

feel that the ISO 9000 standards 

were never intended to 

be vehicles for third-party 

certification, but rather were 

meant to be used internally 

by companies for their own 

evaluation purposes. The 

development of a lucrative 

I third-party certification 

i industry, the concerns of 

smaller companies about 

the high cost of qualification, 

and the debate-s about 

the qualifications of registrars 

and consultants have, 

led some to reconsider 

GEAR STANDARD'S, 

the 

entire ISO 9000 certification 

process. 

The advent of the Big 

'Three automakers' QS-9000 

program has only complicated 

the issue .. This program 

is not a product of the 

original ISO 9000 series, 

but a separate set of quality 

standards which is now 

being demanded by Ford, 

GM and Chrysler. The pros 

and cons of this program 

and its effect on the ISO 

9000 series are the subject 

of still more debate. 

AGMA's Overall Goal 

The development of common 

standards may seem 

glacially slow at times, but 

progress is definitely being 

made. At any given time, 

AGMA has between twenty 

and twenty-five active committees 

at work on one and 

sometimes two or more standards. 

(See the attached list 

of current AGMA projects.) 

In addition, 

some committees 

are working on infonnation 

sheets, which contain 

material that is not included 

in standards, but is, useful or 

needed to apply standards 

effectively. 

----- 

----- 

AGMA's goal is to bring 

AGMA and ISO standards 

into harmonization as soon 

as the gear i.ndustry wiH 

accept a single standard, but 

progress is slow and tedious. 

It takes two to three years to 

revise or develop a standard, 

depending on how active a 

committee is. And committees 

are all made up of volunteer 

members. 

The Best of Times; Tbe 

Worst ofT:imes 

Ironically, times Iike 

these, when business is 

good, can be one of tile 

worst times for standards 

development. Some companies 

are too busy to let valuable 

employees have time 

away from the office to 

attend standards committee 

meetings. On the other hand, 

when business is poor, companies 

can't afford to let 

'employees attend .. Willingness 

and commitment on the 

part of both individuals and 

their employers are crucial to 

the success of the various 

standards committees .. 

International standards 

development may be a bit 

Iike making law and 

sausages-a messy process 

whose result is not necessarily 

to everyone's liking. But it 

is an important one. As business 

becomes more and more 

global, the push to harmonize 

standards,althaugh it may 

come in fits and statts, will 

certainly continue. 0

New Gear Developments at 18 

The international Manufacturing Technology Show provided 

one oj the biggest ever marketplaces for bu,ying and 

sellillg gear-making equipment. with J 21.601 a/tenders. making 

it the largest .lMTS ever. The SllOW took place September 

4-1 J at McConnick Place in Chicago. /L 

The gear industry made a strong presence at the show, with 

the introduClion of the Gear PaJlilion at IMTS. The new focus 

area allowed visitors 10 find most of the companies who sell 8,ear 

manufacturing machinery all ill one place. 

Several key gear industry companies made announcements 

or introduced Ilew machines that should have an impact on 

gear manufacturing for many years to come. 

Gleason to ,Acquire' Plauter Group 

Gleason Corporation shocked the gear industry just before 

the show opened by announcing that. it had reached an agreement 

in principal to acquire all assets of the Hermann Pfauter : 

Group, based in Ludwigsburg, Germany. 

The purchase will include Pfauter's gear machinery manufacturing 

operations in Germany, Ilily and the United States 

as well as the company's 76% interest in Pfauter-Maag 

Cutting Tools, L.P., located in Loves Park,lt. The Pfauter 

Group employs about 1,050 worldwide and had combined 

sales of$175 million in 1995. 

According to Gleason and Pfauter management, the entire deal 

took place over the last few weeks before IMTS and was kept 

under tight wrap so an announcemenl could be made at the show. 

"Pfauter bas long been recognized as a leading supplier of 

cylindrical gear production equipment, as Gleason has for 

bevel gear production equipment The combination of our two 

companies will create an excellent strategic fit that will 

expand our product line. substantially enhance our ability to 

provide our customers fast and effective solutions to their 

gear processing' needs and offer significant benefits from 

combining technology. production capabilities and distribution 

channels," said James S. Gleason, chairman and president 

of Gleason 

Corporation. 

MUsubishi Debuts 3-in-1 Gear Center 

A unique machine that combines hobbiag, deburring and 

rolling in one machining center was demonstrated for the first 

time at !MTS by Mitsubishi Machine Tools USA. 

The GT06R is aimed directly at automotive manufacturers-it 

can produce one AGMA Class 10 gear every .Hl'-!5 

seconds. One machine and one operator can produce gears 

that leave the machine ready for heat treating. 

The machine has a maximum hob speed of 4.000rprn and a 

maximum table speed of750 rpm. It measures 13.2 feet by 11.5 

feet. Also available is a Gf06S model, which replaoeslbe rolling 

function with a shaving function to finish the gears. 

16 GEAR TECHNO~OGY 

Feillows Introduces Direct-Driven Shaper 

The new FS 180 Mark ill CNC Hydrostroke gear shaper 

features six servo-driven axes of motion for higher-speedcutring 

cycles. In addition, the machine is beingintroduced al a 

lower price than that of the previous model. 

The manufacturer claims the machine may reduce cuuing 

cycle times by as much as 35% with speeds up to 2.000 

strokes per minute. It handles pitch diameters up to 7" and 

face widths I.Ip [01 1 /.1,", which makes it appropriate for automotive 

transmission applications. 

Gllesson Knowledge System Demonstrated 

The Gleason Works introduced [I 

new snftware system for its 

PHOEN]X 125GH CNC nobbing 

machine. The software, installed 

on a personal computer, provides 

the machine operator with setup, 

startup. operational, troubleshootingand 

maintenancei nformation. 

The system combines the knowledge of Gleason's technical 

experts to include complete fault diagnostics with suggested 

remedies. a complete set of replacement parts drawings, 

animated tutorials to explain key concepts ami complex 

procedures and training modules to help the user get accustomed 

to the machine interface and control panels. 

Bourn I Koch Redefines Small Footprint 

The Model 25H hobbing machine demonstraied by Bourn 

& Koch Machine Tool Company is a 4-axis CNC hobber for 

I" maximum diameter and 4" maximum face width gears. 

The machine is almost a desktop model, occupying a 30" 

x 30" space on the floor. It includes auto hob shift. double cut 

and crowning capabilities and can use carbide or HSS hobs, 

Star Cutter Introduces Tool & Cutteif Grinder 

Elk Rapids Eng] neeri ng, a subsidiary of Star Cutter 

Company, demonstrated its new UTG-300 CNC five-axis 

tool and cutter grinder, which includes Windows-format software 

for sharpening hobs, shaper cutters, broaches, end mills, 

taper fluted tools and Maag-style cutters. 

Pfa.uter~Maag Introduces Shaving Cutter Lina 

Pfauter-Maag Cutting Tools, LP. 

announced that it has begun offering a completeline 

of shaving cutters, including stan- 

Liard, underpass, plunge and diagonal-Iype

The Advantages of 

Ion Nitriding Gears 

This process can eliminate the need for expensive 

post-best treatment operations. 

Robert lamont 

Jr. '& A. Bruce Craven 

hen it comes to setting the standard for 

gear making, the auto industry often sets 

the pace. Thus when automakers went 

to grinding after hardening to assure 

precision, so did the machine shops that specialize 

in gearing. But in custom manufacturing of gears 

in small piece counts, post-heat treat grinding can 

grind away profits too. 

One alternative that has yet to be fullyexploited 

by the gearing industry is ion nitriding, General 

Motors' Allison. Division has ion nitrided 4140 

steel diesel engine gears, Ford has used the 

process for certain models, and perhaps a dozen 

commercial heat treaters around the United States 

provide ion nitriding services to machine shops. 

Here-from the perspective of a custom gear shop 

and a heat treater-are some of the advantages 

that ion nitriding offers gear makers. 

Advantages of Ion Nitriding 

For .a:ny manufacturing operation, grinding 

adds not only time and labor, but also an element 

of risk. Grinding has become a routine part of gear 

making, primarily because the heat treating 

processes that harden load-bearing parts such as 

gear teeth also introduce thermal stresses that 

cause distortion. But unlike induction hardening, a 

commonly used surface hardening process in 

which gear teeth are hardened. tooth-by-tooth or 

one at a time, ion nitriding introduces favorable 

compressive stresses.

Ion nitriding is performed in a precisionsealed 

vacuum furnace. After the air is evacuated 

(to less than 100 ppm of air), a small partial pressure 

of hydrogen and nitrogen gas is bled into the 

chamber, and the vacuum is maintained at about 

5 torr (atmospheric pressure is 760 torr). Then, 

energizing the parts to a negative (approximately 

500 volt) potential initiates an electrical plasma 

of gaseous ions. The positively charged ions are 

attracted to the part, subsequently reacting with 

the alloy elements of the steel part to form 

nitrides. The nitriding temperature is significantly 

lower than that of induction hardening or carburizing-specifically, 

950°F. Moreover, with ion 

nitriding, there is no need fora liquid quench, 

eliminating another source of adverse stresses and 

distortion. Eliminating most heat treat-induced 

distortion is critical for any manufacturer, particularly 

smaller machine shops with limited 

equipment for secondary operations such as 

grinding and straightening. 

Practical Applications 

How do these theoretical advantages translate 

into everyday practice? At Atch-Mom Gear, a 

good customer requested a Class 10 gear with 

hardened teeth. A Class 10 gear is not that hard to 

machine, but typical practice for a 4140 gear 

(either annealed or pre-heat treated) would have 

been to induction harden the gear teeth only for 

better wear characteristics. The distortion introduced 

by induction hardening or carburizing lowers 

the class number (or precision) because of the 

high process temperature (in excess of 1600°F) 

and subsequent quench. Lacking the ability to 

grind all types and sizes of gears, Arch-Mont's 

only option for returning the gear to the required 

precision appeared to be sending the piece out for 

tooth grinding. This was cost prohibitive. 

Fortunately, Arch-Mont has had some customers 

who requested gas nitriding with ammonia, so the 

company was familiar with.nitriding's low-distortion 

benefits. Solar Atmospheres, a commercial 

heat treater specializing in vacuum processing. 

suggested the piece would be a good candidate 

1'8 GEAR TECHNOLOGY

for ion nitriding. Atcb-Mont told the customer it 

couldn't guar:anlee Class 10, but could ion nitride 

and lap the gear teetn if necessary. The results 

were successful. 

Ion Nitriding Worm and Pinion Shafts 

Worm and pinion shaftsare al 0 good candidates 

for ion nitriding. Parts that are usually made 

from 8620 steel and carburized, or from 0..4 carbon 

medium alI.oy carbon steel. and induction 

hardened need to' be rough machined with exira 

material on the joumals. This allows for finish 

machining to overcome ,ultl distortion resulting 

from carburizi~gor induction hardening. With ion 

nitriding. this is not a requirement. 

Worm gears......:typi.callymade from 8620, 4615 

or 1045 steel-s-have a tendency to 'unravel when 

carburized or induction hardened (because of the 

higher temperature process), whlch means they 

have to be ground afterwards to make them 

straight and true wi.th respect to the bore (or centerline). 

~t Atch-Mont, engineers found that by 

makingdrte gears of pre-heat treated 4140 steel 

and ion nitriditng them, nearly the same hardness 

could be achieved. Herringbone gears will 

respond with the same positive results. 

At Solar Atmospheres, gears in the 10-12" 

diameter range are commonly ion nitrided,and 

gears. of up to 30" in diameter can be accommodated, 

Gear materials most commonly ion nitrided 

are the medium alloys-11he 4000 and 5000 series 

steels and, occasionally. the 6000 series steels. 

Stainless steel, which is very hard to gas nitride 

without mechanical or chemical surface treatrelatively 

easy; i.e., gears can be stacked, permitting 

rtitriding of the teeth with just the topmost 

pieces requiring a mask to cover the face and 

bore. But even when :individual pieces have to be 

masked with a stop-off paint-a time-consuming 

but effective process-c-Atch-Mont Gear feels it's 

well worth it to "get the gear we want." 

Currently, ionnitriding is used for gears up to 

30" or 36" in diameter. In fact, the authors believe 

it is technically feasible to produce ion nitrided 

gears that would compete with many carburized 

gear applications ..Most ion nilriding beat treating 

shops do not have the equipment capability to 

handle the 30" or larger gears. 

One of the factors contributing to the relative 

scarcity of ion nitriding is the high cost of the 

machinery required, As interest and demand 

increases, however. the large capital outlay is 

being overshadowed by the business potential, 

and companies like Solar Atmospheres are looking 

to this area ~orexpansion. 

It ]s this heavy investment in equipment, as 

well asa lack of education as to the potential of 

ion nitriding, that the authors believe have kept 

the process from taking off in the United States as 

it has in Gennanyand other European countries. 

In addition, equipment problems when ion nitriding 

was first introduced in this country created 

the image of an unreliable process that has stuck 

in the minds of some engineers. While this is,:no 

longer a valid objection. it is true that ion nitridiag

t~es CO~f,.,ide.Il,' ce,' to, ·,be th,er:r.st 

to Invest 111 new manufacturing 

technology. But the payback 

can be significant. That has 

been the experience at the Ford Motor 

Company's Transmission & Chassis 

Division plant at Indianapolis, IN, 

which boasts the world's first production 

application of dry hobbing. 

Beginning in July 1994, Ford began 

installing Liebherr LC 82 CNC hobbing 

machines to hob steering pinions (SAB 

1045,22 Rc). According to Ford manufacturing 

engineers, dry hobbing with 

carbide cutters has reduced machining 

costs by 44%, shortened cycle time by 

48% and increased tool life by a factor 

of 6.. So far. 

Goal No.1: Improve Pinion Quality 

The task at Ford's Indianapolis plant 

was to improve gear qllality-swface 

finish and pitch diameter runout=-and 

meet increased production demands. 

After determining that existing bobbing 

View of the pinion, hob and tailstock in the Liebherr LC 82. The workpiece load/unload mechanism 

built into the bobber: closely coordinated' with workpiece clamping. reduced Ford's chip-to-chip time 

to about 4 seconds. 

20 (HAR TECHNOLOGY 

machines using standard coated HSS 

hobs with coolant were incapable of 

meeting the plant's targets, the engineers 

investigated new technology. 

After extensive research and subsequent 

testing at Ford, carbide bobbing 

without coolant showed the most 

promise in meeting quality goals and 

offered the additional potential of greatly 

extended tool Ijfe and lower maintenance 

costs. Duringtest cutting of the 

steel pinions, the process demonstrated 

a Cpk of 3.0, and tool life was far longer 

than was achieved with any steel hob, 

The process testing was completed 

using carbide hobs on a Liebherr CNC 

hobbing machine specifically designed 

for carbide dry hobbing. 

More Speed, Greater Horsepower 

To properly utilize the advantages of 

carbide, a hobbing machine must be 

capable of increased speeds and greater 

horsepower than is typical of conventional 

machines. The Liebherr machine 

table can achieve speeds up to 450 rpm; 

the hob head is equipped with II heavy 

duty drive that permits speeds up to 

3,000 rpm with drive power to 18 kW 

(25 hp), several times that of the conventional 

bobbing machines at Ford. 

The combination of carbide hobs 

with maximum diameter of 90 mm 

(3.6") and the new machines, which 

have cutter spindle speeds of 2,000 rpm, 

enabled hobbing at 850 sfpm, much 

greater than the capability of conventional 

production machines. 

The higher cutting speed reduced 

machining times to approximately 22 

seconds from 42 seconds previously 

with HSS. A workpiece load/unload! 

mechanism built into the hobber and 

closely coordinated with workpiece

clamping reduced Ford's chip-to-chip 

time to about 4 seconds, 

Because the pinions are held rigidly 

in place during machlning by hydraulic 

gateways driven by cams, part movement 

or deflection is prevented, and the 

potential for runout, teed scalloping and 

chatter marks is reduced. The result is 

that surface finish improved to between 

.5 and .75 Ra from U to 1.5 Ra. 

In the first year of production, Ford 

Indianapolis immediatelyachieved significant 

gains, in tool life, more than offsetting 

the higher initial cost for carbide 

cutters. Becau e heat is the main factor 

affecting tool life. 

the engineers made 

severill further changes to allow the cutter 

to run even cooler, These included 

different. coatings, recently developed 

carbide materials and hob geometry, 

To reduce heat build-up at the edge of 

the cutter and increase the shearing 

action, the rake angle was increased to 

5°. The number of gashes was reduced 

to 12 from ]5, allowing more room for 

chip evacuation. 

Docum.ented Benefits 

Data from the Ford experience clearly 

points to the benefits of dry hobbing, 

According to Ford manufacturing 

engineers, 

tool life improved to 252,000 

pinions per hob (14 regrind " using dry 

carbide from 39,000 pinions per HSS 

hob (12 regrinds) on existing wet cutting 

machines. Machining cost feU by 44%. 

In addition. Ford found that the process 

is very stable, maintaining exceptional 

consistency well withicthe process 

capability specifications. 

Increasing the cutting edge rake 

angle and changing the coating to TiAlN 

is now being testedvand Ford is now 

achieving up to 33,000 pinions per 

Dry bobbing. produces Ford steering' pinions ill 

48% less lime. at 44% less cost and improved 

gear quality. 

regrind, with the potential of getting 

nearly 300,000 pinions. per cutter. 

The primary goal was to improve 

quality and production economy, but the 

plant also achieved a Ford 2000 environmental 

goal by eliminatingthe use of 

cutting oils and coolants. Operators like 

the rapid, coolant-free cycling, It's environ:mentaIly 

safer and cleaner with no 

cutting oils and mist 

A search for a better quality pinion at 

Foro Motor Company yielded a process 

GEAR 

that not only produced a better surface finish, 

but reduced piece cost and cycle time. 

It also provided tile additional advantage 

of coolant-free operation, saving co 15and 

improving operator morale. 0

tlIring lines in the automotive industry 

have teamly i.ncreased. Quieter gears require

!.be different types of chamfers on gear teeth and 

outlines manufacturing methods andgui.cfelines to 

determine chamfer sizes and angles for the product 

and process engineer, 

Wby Chamfers? 

Chamfers are needed in gears: 

• To prevent nick and bump damage along the 

active looth surface after the shavi ..ng or fiaishing 

operation; 

• To prevent bum and sharp edges which call e 

gear noise; 

• To prevent the break-off of burrs and sharp 

edges duri~g torque lransfer wben the gears have 

been assembted in boxes or triUlsfer cases; 

• For cosmetic 

reasons. 

[0 the last few years, gear manufacturers have 

intensifiedtheir efforts to prevent or reduce nick and 

bump damage. Handlil1g system have ratchet conveyors, 

which prevent the gears from touching each 

other, Special baskets are used to protect. the gears 

from accidental damage d1.lr:in,g beat treatmenl: ! 

process. Operator training has . tressed the careful ! 

handling of gears at every tage of production. ln 

spim of a1Ilhesesteps,. the problem still persists. The 

number of gears :rejected because of nicks can range 

from ]()-.6()% of a batch. Nicks modify lead or invo- 

IUm charact.eris:tics, causing meshing def'eCts. 

Chamfers sign:ificarlUy reduce noise while me 

gears mesh and effectively protect all vulnerable 

zones in the gear tooth.

chamfer in cylindrical helical gears produced by 

cutting. g-rindi:l1gor rolling operations. D is lite tip 

chamfer on end faces produced during the turning

The lip chamter along the lead i generally 

executed while cutting the gear with either a bob

When all:: 2.0°, ti,li m 

:: O'()()2" (.0..055 rum). 

This variation is close to 5.0% of the nominal 

value of the chamfer size. This becomes much 

more significant when we are dealing with gears 

with. a normal diametral pitch (NDP) of more 

than 2.0 (or module 

less than 1.25). The tolerances 

of the O.D .. and the tooth thickness exceed the 

chamfer's nominal value. It then becomes necessary 

to cut the gears with "topping" tools, which 

simultaneously cut the teeth and the 0.0. 

Sometimes when it is necessary to use as 

much active profile as possible because tip chamfers 

reduce the working diameter and the line of 

action, gear designs do not allow tip chamfers, In 

some rare instances, amy a few tenths ofa millimeter 

makeup the meshing continuity. Such 

constraints must be resolved during the early 

stage of a transmission design, and the designer 

must make accommodations for tip chamfer. 

The chamfer "0" on end faces is required for 

assembly purposes and for smoother meshing. 

The chamfer "0.,." which is put on the gear during 

runting, can actually cause more nicks than it prevents. 

Usually the project engineer requires an 

end tip chamfer without paying too much attention 

to its size. From Fig. 3, it can be seen that as 

chamfer "D" is increased, chamfers "AU and "B" 

provide less protection. Therefore, it should be 

made as smaIl as possible and never lar-ger than 

the value 

Sd:::: O.S(a + b) 

Another reason favoring reduction of the end 

tip chamfer to a: minimum is the presence of hobbing 

and shaping burrs in this area. These burrs 

are not removed by the usual deburring tools and 

may be difficult to remove if they are large. 

Smaller burrs usually disappear during heat treatment. 

or shot peening. If the chamfer "0" is large 

and has a heavy burr, sometimes it is necessary to 

employ an additional deburring tool. 

From Fig ..4, it is dear that in the absence of an 

edge chamfer, poi:ntA is more exposed to nicking, 

With. an edge chamfer, the most exposed point, 

A I, is shifted towards the ins ide and is therefore 

less prone to Ilicks..The tip chamfer is rendered

useless unless there is an edge chamfer. Edge 

chamfer dimensions do not have the constraints of 

tip chamfers., since they are mad.e after the gear 

teeth are cut. Their dimensions are to some extent 

independ m of gear tooth tolerance . Chamfer 

size range from 0.012" (0.3 mm) to 0.030" (0.8) 

rnm. The angles need to be set so that the expo ed 

points are as far .away from '!he ends of the tooth 

as po sible (see Fig. 5). A the heliix angle increases, 

the chamfer angle (related to the 'tooth axis), 

decreases to less taan 20°. For example, a 30° 

helix angle will lead loa [SO charmer angle ..There

with a tep, Sometimes it is better to chamfer 

the root fiUe! even if thrs area is Datu ceptible 

to nicking .. fig. 7 shows the correct procedure 

for chamfering .. 

Production Methods 

Edge chamfers can be produced by three different 

methods, 

A. cutting ope.r.alion. There are two cutting 

methods. The machine may 'be designed to have a 

milling cutter and a gear train of CNC equipment 

to generate an involute. The milling cutter can be 

heM steady with only one circular peed along its 

axi . In Ibis case, the chamfer is uniform and parallel 

to '!he !involute. This method producesagood 

chamfer, and there is no Deed Ior any additional 

deburring operations. On the other ~and, milling 

is a costly operation, and it is difficult 10 chamfer 

gears lying adjacent to a. shoulder u ing this technique. 

Cycl.e times are long in tbits method 

because of indexing, and too] life is poor. 

A second way to cut a chamfer is to use a gear 

train or CNC equipment to index in conjunction 

with a cutter. The cutter has a reciprocating 

motion timed with the iadexing motion. This type 

of operation u ually produces the chamfer along a 

traight lille. The advantage of this me!hod! is !hat 

no further d.eburring operation is required. Among 

the disadvantages is the fact that this method creates 

an uneven chamfer ,extending ,through the 

whole root. Sometime burrs are [eft on the gear in 

Ule root area. Chamfering gears adjacent to a 

shoulder is also difficult with this method. Again, 

cycle times are long. and tool life is poor. This

approach also requires a lot of eperator assistance 

to. maintain a good setup. 

A grinding operation. Ell this method, a grinding 

wheel is used to produce the ctlamfers; The 

advantages are low cycle timesand acceptable

creating Clean Air Act compliance preb- 

Iemsand raising 'concerns about employee health 

and general environmental ethics. To eeunter the 

pollution. effecss, expensive fIlters and dust collectors 

are needed. Tiny bUJ'fS are created along the 

involute, amd they need an extra Cleaning operation 

like shot peen blast. A lot of operator assistance 

is required to mainlain a good setup, 

A rolling opermion ,using special c.laarnfer 

tool&. This operation involves driving a chamfer 

tool in mesh with the gear under pressure. The 

pI1essure wtllplasticaHy deform the material, producingtbe 

chamfer. Most of the material 

deformed plastically will flow out of the ides A,

OJ}OO8" (O.02.mm), will rise up tiny ridges 

inside the involutes E. F. G and H. and a very 

small portion will rise out of the tip chamfer (D) 

(Fi.g.I) produced bya turning operation. Because 

of this, the operation must be followed bya finishing 

operation like shaving or grinding ..II is not 

recommended for finished 'cut parts.

and Dandthe burrs produced dtrringtbe cutting of 

the teem are removed! by a spring-loaded deburr 

tool. The chamfer and deburr operations must be 

carried out simultaneollsly to avoid pushingfhe 

burrs into 'the gear teeth. after cutting. The chamfer 

tool willforce the burrs out for a cleaner cut by the 

deburr tool. The material raised! aIongthe . urface 

D can be minimized by designing the chamfer tool 

with an operating pressure angle that minimizes 

the sliding velocityl.oward the tip. A pair of bur- 

Ilishingtoo.ls can. be added to the deburrtoel group 

to remove the raised materia] along D. 

The main advantage of this method i extreme- 

.Iy tong cutter life. It is quite common to chamfer 

more than 100.000 parts between resharpeaing, 

The machine cut cycle time is only 3-4 seconds. 

while the floor-to-f1oor cycle time varies from 

7-15 seconds for pinion gears. Constant sizes. of 

chamfer parallel to the involute and chamfering 

!he root are possible. This method can chamferl 

. deburr any adjaeem houlder both. on the gear side 

and the groove side. 

Some stress points should be considered when 

producing edge chamfers by rolling. The plastic 

deformations of the material should produce 

residual tresses along the involute surface chamfer 

that would ~ocany increa e the airface stress 

limit and reduce the stress concentration factor, 

thus enhancing .the overaH resistance of the chamfered 

gear. It is essential to charmer not only the 

acute angle called for on most drawings. but also 

the obtuse angle. This gives better protection from 

nicks and bumps. and en ures homogeneous 

behavior of both the Hanks of the gear under load 

because of the residual stress. 

For simplest applications. the tool used on 

chamfering and! deburring machines consists of a 

set of chamfering tool and a. et of skiving tools 

to deburr lateral surfaces. Because of the force 

between the too]'s springs and the gear's width. 

once it enters into the tools. the two deburring 

tools will spread open. Chamfering and deburring 

tools run free on their own qllill and elf-center 

themselves 011 the center line of the gear, thus 

assuring symmetrical chamfers and complete 

removal of bWTS, 

The tool group on 3..one-head machine in the 

imple t form consists of one et of chamfer bevel 

gears and one set of cutter eli cs mounted together 

as a gang. The workpiece drives the complete tool 

group, since:it is in mesh with thechamfering tool. 

The various types of chamfers that can be 

achieved on either pur or h licalgears cover the 

whole range usuaUy required for amy cylindrical 

gears. Examples of feasible chamfers include a) 

chamfering only 011 one flank. without the root; b) 

chamfering both flanks withoutthe root; c) chamfering 

one flankand part of the root; d) chamfering 

the complete profile; e) chamfering inclined 

faces. (see Fig. 9). 

Each problem can be evaluated individually and 

tooling engineered to suit pecific applications, 

Cluster gears can be chamfered and debmred with 

machines having nUlltiheads wiIh two woJlting stalions. 

To work. different gears on the same machine. 

the tools can be designed to keep a constant center 

distance between IfIe workpiece and the too! in order 

to reduce the changeover time.

'CbamferiQg 

Tools, 

Chamfering tool are engineered to generate 

th chamfer on the edges of the gear teeth. The 

chamfer i made bythe rolling action of chamfering 

tools. In effect two bevel. gears mate with 

the work gear only alomgthe comer edge of its 

teeth. The foroe"F,''' provided by a pneumatic 

cylinder, represents the thrust neee sary for 

rolling (see Fig. W). Because of their bevel gear 

.hape and balanced application (one pair of identical 

teo! ymmetricaUy coupled). oppo ed axis] 

tre esare generated during rolling ..A the tool 

group i free to move axially. il centers itself on 

the centerline of the gear width. 

Uthe two tools are off center as in Fig. llA. 

after the 1001. grol.lp is engaged, the gear will 

move axially until the forces are balanced. The 

final po ition is shown in Fig. U B. This makes 

the chamfers symmetrical. The e tools will work: 

,either pur or helical gears. 

Fig. 12 describes a chamfering tool tooth, 

Be ides being tapered, the teeth have an involute 

form enabling them to mesh with the gear and 

roll on its comers. 

The angle of the tooth flanks of the chamferjog

angle of chamfers to be generated (Fig. 13).

In order 'to have the chamfers correctly executed. 

the chamfering discs mu t be in uch a

Special Cases

cannot be completed all. along the profile. The 

chamfer must end etJeast .o.m2" (.0.3 mm) 

before 8 step or a radius begins. In cases where 

the gear has an angled side face, it is necessary 

to engineer tools wilih properly modified. pressure

DcbuFF Tools 

Deburring tools are large diameter discs who e 

rl external rims are ground to the rake angles necesary 

for cutting action. The di tance between the 

two discs is aotconstanr because they can move 

axially either under the action of the springs 

("m" 

shown in Fig. 14) or as a can equence of the self- 

'centering with the gear to be deburred, 

In the rest position. the spring pressure on the 

deburring discs brings their separation distance to 

a minimal value, which is about 0.008" (0.2 mm) 

less than the minimum gear width .. Ifthe distance 

betweenl.be discs were fixed, the discs themselves 

would hit the outside diameter of the workpiece, 

chipping it when discs are plunge-fed 

toward the workpiece. To avoid this, the cutting 

edge of each di c is provided with atapered leadin 

whose ize is large enough to avoid hitting 'the 

out ide diameter of dle gear to be deburred. The 

first contact must occur between the lead-in surface 

and the workpiece outside diameter. 

The deburriag discs are rotated by the workpiece 

Itself, and the burrs are removed through a 

true skiving actien on the gear lateral faces. 

Generally 100,(}()() pieces or more in some ca e. 

can be deburred before resharpen.iog the tool. The, 

tool life between resharpenings depends upon a 

number of factors, They are 

• The hardnes and machinability of workpiece 

material; 

• Thethickae s of bum and the size of the 

requested chamfer; 

•.The length of the deburred area (workpiece 

whole depth); 

'. The presence of steps. radii or shoulders •. 

which may interfere with the tool cutting edge; 

• The correctre harpening and as embly of 

the tool group. 

Special Cases 

For gears with sh _ulders or radii, special types 

of deburri:ng tools are designed for a. correct 

action of the debll.rrin-ll discs in order to avoid the 

interference, To deburr a gear with a radius (see 

Fig. 15), a special type of deburring 1.001 known. as 

an URn type tool is u ed. Due to the pring loading 

action, the burrs are uniformly and cleanly skived 

offlhe surface by the tool following the profile of 

the gear, The same tool also performs the debur-

ing of the straight portion ..The radius form protuberances 

A are alternated withthe cutting edges a, 

which work the straight portion of surtace S like a 

standard deburring tool. Protuberances A remove 

burr from the radii by means 'Of the true cutting 

action of the cutting edges C or D according (0 the 

direction of rotation. Portion a skives the straight 

faces as far as .008" (0.2 rom) to 0.012" ~O.3nun) 

above radius Rl. 

When the surface to be deburred is tapered. 

specially tapered debuning tools with many 

inclined slots are used to generate an adequate 

number of sharp cutting edges. During helical 

gear cutting with ,eiU\er a hob 'Or wilh a shapee 

cutter, burrs are usuaL1iy left on the acute edge 

(where the too] comes out of the gear) ..The relative 

traverse movement between the deburring 

tool and the gear must push the DllIT toward! the 

tooth and not toward the space. 

Deburring Tool Sltarpening 

Wear can be removed by grinding ,either surface 

E or surface H (see Fig. 16A). Stock size 

removed must be 0.008" (0.2 mm) or its multiples 

in the direction of the disc's axis. The disc 

thickness reduction is compensated for by shifting 

the spacers .. 

With no gear between. the 'tools, the discs are 

in the conditions shown in Fig. 16B. The springs 

push tile disc and the spacer against Ithe shoulder 

flange. When the gear enters the discs, it forces 

Ithe discs apart, thus, moving the tool f:rom the 

shoulder flange and creating a gap approximately 

0.1004" (0. ~ rom) between flange and spacers

18 Things You Should now 

A1bout SPIC for Glea1rs 

Dr. H'ans Ba,j:aria 

mtatistical Process Control (SPC) 

and statistical methods in gener- 

I 

al are useful techniques fOFidentifying 

and solving complex. gea.r 

manufacturing consistency and performance 

problems. Complex problems 

are those lllat exist in spite of our best 

efforts and the application of state-ofthe-art 

engineering knowledge. 

Statistical methods approach these 

problems results-backward as opposed 

to knowledge-forward. For example, the 

knowledge-forw.ardapproach would 

seek consistencies in gear profile. lead, 

rollout, etc., with. the assumption that 

consistencies improve performance .. 

The resu lts-backwardapproach, on the 

other band, win analyze me situations 

starting from assembly performance. It 

will then relate performance variation to 

specific gear characteristics. 

In other words, we use our gear expertise 

ina knowledge-forward approach. 

When this fails to solve a problem, we 

should use the results-backward approach. 

Onoe critical gear characteristics 

are determined, we can begin attempting 

to achieve consi tency, 

Let us begin by describing six SPC 

fundamentals and six statistical applications 

for gear design and manufacturing. 

These will lead us to an effective 

sequence for applying statisical methods. 

Six Fundamental of SPC 

SPC is only a subset of statistical 

methods helpful in analyzing complex 

problems. These meiliods can be a useful 

set of tools for carrying out investigations 

of our manufacturing processes. 

SPCcan chart the output of any process 

to examine whether the process condition 

is stable. has an excessive variation 

or is off-target. Furthermore, SPC cen 

offer dues to strategies for correcting 

these conditions. Additional statistical 

tools can help us establish relationships 

between problematic process conditions 

and suspect variables. 

1. Multivariate (T2), Charts are useful 

in understanding and controlHng correlated 

performance characteristics. The 

performance characteristics of assemblies, 

such as noise, durability, ease of 

maneuverability, etc., are likely to be 

correlated ..That means •.for example, that 

trying to reduce the noise may result in 

losing maneuverability. or improvement 

of maneuverability may result in a 

reduced durability.and so on. The problemsassociated 

with correlated characteristics 

can only be defined with the use 

of a multivariate chart (see Fig. I), 

2. Mullivariate (J'Z) Charts are also 

useful in understanding and controlling 

input gear characteristics. 'Gear characteristics 

are most likely to. be correlative 

because they are generated simultaneously. 

In practical terms, we can state 

that when characteristics are correlated. 

each individual characteristic can be 

witllin specification, and yet jointly they 

constitute a statistical instability. 

3. Multi·vari Char:ts are useful in 

analyzing size as well as shape problems. 

For example, four 'teeth on a gear 

measured by conventional means may 

all individually be within specification. 

and!yet differences among them may be 

the root cause of a problem. A proper 

way to define a problem that takes into 

account characteristics of each tooth 

individually as well as differences 

among the four teeth is a multi-vari 

chart (See Fig. 2). 

Multi-veri and multivariate charts 

are different Multi-veri charts analyze 

variations within a given characteristic, 

whereas multivariate charts analyze

4. Multivariate AnalysiS is useful in 

analyzing process instabilities, and relating 

them to process variables, An instability 

is characterized by an abnormal 

condition on a control chart. To understand 

the source of unstable behavior, 

we generally analyze process variables. 

If process variables are stable, tilen we 

look: for the explanation elsewhere. 

Multivariate analysis captures the 

missed opportunites in analyzing process 

variables that we have prematurely 

concluded to be noncontributory. For 

example, (A) incoming material condition, 

(B) workpiece speedland (C) 1001 

feed may all appear to be within nonaal 

range when analyzing an instability visible 

on a control chart Conventional 

wisdom leads us to look: elsewhere for 

the root cause. A multivariate chart will 

offer additional help by analyzing T2AB'

may remain a mystery. 

5.. Multiple Regressioll Analysis is 

useful inestabHshing relationships 

between gear performance characteristics 

and gear eharecteristics. Neither 

worst-case tolerancing nor statistical 

toleranciJng alone are sufficient to fully 

understand how gear characteristics 

affect the performance of assemblies 

containing gears. Such understanding 

can only be developed through probabilistic 

relationships based on actual 

data rather than any theoretical. considerations. 

Multiple regression analysis 

helps develop this relationship. 

6. .Monte Carlo Simulations are 

computer-based, iterative statistical procedures 

wherein we determine targets 

and ranges of critical gear characteristics 

to match targets and ranges of performance. 

The inputs to the simulation 

processes are probabilistic ,equations 

and targets and ranges of gear characteristics. 

The output from the simulation 

processes are the target and range of 

performance (see Fig. 3). 

Six Applications for SPC in Gear 

Manufacturing 

1. Acceptable as well as unacceptable 

production of gears can best be 

characterized by using SPC. Gear characteristics 

that fall within specifications 

are not in themselves indications of the 

quality of the processes that produced 

them. For example, an acceptable gear 

profile is judged by a specified eavelope 

..However, the process that created 

the envelope is a multivariate process; 

that is, three characteristics that make 

up the gear profile-tip, formand high 

point-are produced simultaneously, A 

correct judgment about the process condition 

responsible for these characteristics 

can only be made with a 'f-l chart. 

Any decisions regarding process actions 

based on specifications tend to produce 

either overreactions or underreactions, 

WJillegear metrology is very advanced, 

it does not go far enough in integrating 

SPC for process actions. 

2. Effects of design and production of 

gear characteristics on gear performance 

can best be characterized by using SPC. 

Gear characteristics are simultaneously 

·54 GeAR TECHNOLOGY

• ,GEAR FUNIDAMEN,TA'lS, _ 

generated and therefore, we must judge 

their acceptability together. rather than 

discretely. The issue of joint acceptability 

does not get ,enough coverage either in 

standards or at gear design and manufacturi_flg 

conferences. 

3.. Output performance characteristics 

of assemblies containing gears, such 

as durability, noise, ease of transmission 

under quickly changing inpUIS and smoothness 

of transmission, are correlated to 

one another. Knowledge of these COrrelations 

is critical to the SPC of assemblies 

..These correlations can be quantified 

using statistical methods. 

4. Suspect gear characteristics that 

contribute to poor performance of assemblies 

are most likely correlared to 

one another. Knowledge of these correlations 

is critical to the SPC of gear 

manufacturing processes. These correlations 

can be quantified by using statistical 

methods. 

5. Manufacturing precision of gear 

characteristics is uneconomicall until statistical 

relationship between gear characteristies 

and assembly performance are 

first established. In one example, a. lead 

variation was found to be almost 95% out 

of specification, and yet assemblies containing 

the gears with such excessive 

variation only suffered 5% reject rate. If 

we rush to solve the lead variation problem 

at great ex-pense, 'there is no guarantee 

that the 5% assembly reject. rate will 

go down. How a 95% out of spec gear 

characteristic can cause only a. 5% 

assembly fallout can be explained only 

through statistical relation hips. 

6. Without the use of statistical methods, 

it is almost impossible to separate 

the effects of machining and! beat treating 

on manufacl:uring variation. Without 

such clear separation, fully resolving 

variation problems is impossible. 

Recommended Sequencef'or 

Deploying 

SPC & Sbttisti.ca'l. Methods 

L Establish a statistical relationship 

between assembly performance and gear 

characteristics. Then select eight assemblie 

with acceptable penormance and 

eight assemblies with borderlineor unacceptable 

performance. It may not be easy 

to find ]6 assembne if you are in the 

prototype stage. In thatcase, 

select the 

foUowing alternate route to generating 

16 assemblies. Take two assemblies. Any 

gear assemblies will. have a minimum of 

four pans. By swapping these four parts 

'between two assemblies, you can generate 

16 assemblies for purposes of statiscia] 

analysis. Use multiple regression to 

analyze the data ami. generate an equationbetween 

performance characteristics 

and gear characteristics.

process output is homogeneous or heterogeneous, 

Do this by taking a group of five 

consecutive pieces and examining its 

range. If the range is one-half of the specification 

range or lower, the process output 

is homogeneous. Otherwise it is beterogeneous. 

If the process is homogeneous, 

use X-MR charts for monitoring 

process output. If the process is heterogeneous, 

use X-R charts. 

6. Because differences among teeth 

are contributing factors to ultimate gear 

performance, a muld-vari chart must 

accompany all the other charts to understand 

and control tooth-to-tooth variation 

within a gear.

Red Ring revolutionized the broaching industry with its 

innovative BV-T series -- the first vertical design that 

eliminates the need for pits, platforms, and even 

production-line alterations. The BV-T systems are 

compact, easy to integrate, allow ground-floor 

access, and simple maintenance. Variable 

positioning permits workpiece loading and 

unloading at either the top or bottom of the 

stroke. Finally, to speed-up the entire 

production process, Red Ring offers an

Gear Technology's bimonthly aberration - gear trivia, humor, weirdness and oddments for the edification and 

amusement of our readers. Contributions are welcome. 

In our unceasing attempt to further 

educate our readers-and find 

new and creative ways to waste 

time at work-the Addendum 

staff has spent many long hours (and 

many dollars on popcorn) to bring you 

our latest research on gears in film. 

We'll be assigning ratings (1 gear = 

pretty awful; 4 gears = terrific) to the 

movies based on the following qualities: 

impressiveness of the gears, relevance 

to the plot, prominence in the film, star 

quality and dramatic interpretation. 

Modern Times (1936). Our nominee 

in the Classic Gear Movie category is 

Charlie Chaplin's last film without dialogue 

(or almost without it anyway), 

and may be one of his finest. In it 

Chaplin plays a hapless victim of modem 

factory life, while a very young 

Paulette Goddard plays his love interest, 

known only as "The Gamin." 

The plot, which might have been cowritten 

by Charles Dickens, Victor 

Hugo, Scott Adams andtliIe Monty 

Python gang, is a darkly comedic look 

at the Depression-era struggles of ordinary 

people trying to survive in an 

industrialized society. 

We're sorry to say that the gears play 

metaphorical villains, but they're nasty 

in the grand tradition of movie bad 

guys, If not quite as evil as Olivier's 

Richard HI or as funny as Alan 

Rickman's Sheriff of Nottingham, they 

make worthy symbolic opponents, 

and they're considerably more obvious 

as symbols than Charles Foster 

Kane's Rosebud. They're also very sexy, 

as gears go, and they film wonderfully 

in black-and-white. 

Our only quibble is that in a couple 

of crucial scenes, some of the gears are 


running backwards. But then maybe it's 

not fair to expect someone to be both. a 

directorial genius and a gear engineer. 

Rating: 0000, 

The Rock (1996). An action/adventure 

flick: with Nicolas Cage as an FBI 

biochemical weapons specialist and 

Sean Connery as the only man ever to 

have escaped from Alcatraz, 

The gears-or in this case, gear 

segments-come into play after terrorists 

steal some chemical weapons and 

take over "The Rock," Connery, Cage 

and a small band of Navy SEALs must 

sneak into Alcatraz, disarm the 

weapons and save San Francisco from 

total destruction, 

At a crucial point in the plot, 

Connery must roll underneath a series 

of giant pendulums with gear teeth on 

their bottoms while avoiding spouts of 

flame shooting up fromthe floor. We're 

not entirely sure what this contraption. is 

supposed to be. The gear teeth don't 

Lf,Ff HIS ooo,en.iS IN 

TH€ CoN,'(&:I:,ENC( Aool'-1 

appear to mesh with anything, and we 

don't know why flames are shooting up 

from the floor, but it's really cool and 

scary-looking. Rating: 000. 

The Metapbysics ali' Gears 

To answer the question, what IS a 

real gear, we have consulted no less an 

authority than Eliot K. Buckingham. 

Mr. Buckingham comes down on the 

side of the stationary objects. He says, 

" .. , to my mind, a single gear is a piece 

of metal with projections on it A gear is 

designed to be operated with another 

gear or gears. You do not design a single 

gear ... 

"If a. gear has to be moving to bea 

gear, what are all those things in planetaries, 

and often differentials, that don't 

move, but are absolutely necessary to 

proper performance, and have all the 

appearance of being gears, with teeth 

and all?" 

He approaches the "Biggest Gear in 

the World Question" using the same 

logic: "Actually, the largest gear in the

The quality enhancement and 

cost-saving possibilities of todays 

CNC honing are worth exploring. 

Honing is a hard finishing process 

that utilizes a honing tool in the form 

of an internal gear to improve tooth 

geometry and surfaoe texture of 

hardened gears. 

The Gleason-Hurth ZH 250 eNC 

Honing, Machine combines easy-tounderstand 

operating software with 

complete CNG process control. 

All operating aspects ar'efully automatic. 

Integrated part load/unload 

automation is optional.

:Steps 

In some 

cases, a 

HoblHeat Treat' Hone sequence 

can eliminate a previously-required 

shaving operation while improving 

quality. Depending on stock removal 

and quality requirements, honing can 

potentially replace grinding, with 

significant cost savings per gear. 

Honing can also be added to 

enhance shaving or grinding to 

meet today's stricter quality and 

noise requirements. We can help 

you aJ'laJyze your current methods 

to determine if honing can be, 

productively applied. 

Whether the solution 

involves hobbing, shaving, 

grinding or honing ...or any 

combination ...we have the 

proven technology, and 

we back it with Gleason'a 

worldwide' training ard service 

support.
