Gleason No. 432 (116) Hypoid Generator SCF-ABEX-0074 GLEASON-000150 Advantages The No. 432 Hypoid Generator is a semi-automatic high-speed machine lor cutting spiral bevel, Zerol bevel and hypoid gears. The machine is outstand ing tor its range ol work--capable ol roughing and finishing both gears and pinions. It handles diameters up to 18 inches, and gears ol 2 diametral pitch and finer. _ This generator otters many advan tages: highest quality ol product, high production rates, long cutler Trie, easy setup and operation, simple develop ment of tooth contact and the use of the Unitool method. Arrangement tor tilt of Cutter Spindle. Actual cutter tilt is 0-30 with no limit on swivel angle which controls the direc tion of the tilt. Highest Quality Excellent quality is maintained at all production rates. Complete control of tooth contact shape, size and position is provided by the range of machine adjust ments. Exact duplication of repetitive jobs is assured owing to the rigid design and construction of this machine. High Production Extremely efficient cutting cycles are provided by the feed and generating mechanism for both generated and non generated gears. Changing the machine from one job to another is facilitated by the conven ient location of verniers, controls and other adjustments. If the machine is to be used for volume production for automotive type work, it can be equipped with special cams. These cams vary the rate of roll so that the cutting blades remove equal amounts of stock during all portions of the generating roll--increasing produc tion by 50%. A mechanism precisely positions the cutter and the work each time the sliding base is withdrawn for dechucking. This feature eliminates the neces sity to locate the stock dividing gage in relation to the work arbor each time a new workpiece is placed on the ma chine--saving time and eliminating a source of human error. Long Cutter Life Rigid cutter spindle mountings and efficient cutting cycles assure long cut ter life on the No. 432 Generator. Easy Operation The No. 432 Hypoid Generator incor porates many adjustments which con tribute to fast, accurate machine setup and ease of operation. Hydraulic move ment of the sliding base to and from the cutting position is provided to increase the speed and convenience of chang ing the work. The No. 432 is also equipped with a double-acting hydrau lic chuck, which is easy to set up and has the advantage that uniform, torquefree chucking tension is always obtained on the work. Cutter truing and stock dividing fixtures are accurate and easy to use. Use of Unitool Method With the Unitool method, a single cutter of each standard diameter is us for cutting a wide variety of spiral beve., ZEROL bevel and hypoid gear ratios. The method is intended for cutting gears in small quantities and is particularly useful where experimental gears are needed for prototype models. Since the method is based on just six standard cutter diameters, only a minimum of tool ing is needed, and the calculations are comparatively short and do not require specially trained personnel. The gear member of the Unitool pair is produced on the No. 432 Generator with or with out generating roll and the mating pin ion is generated to run correctly with the gear. Simple Development Any desired tooth contact can read ily be obtained on gears produced on this machine. The many adjustments which have been incorporated on the No. 432 permit refinements of tooth contact. GLEASON-000151 Features A proven type of cam-actuated genjting and feed mechanism and uni versal cutter tilt are two outstanding fea tures of the No. 432 Hypoid Generator. These, coupled with the rigid construc tion, contribute to the high quality of product and efficient cutting cycles of this machine. The No. 432 Generator is equipped with a double path feed cam--one path is used for roughing and finishing gears by the Formate Unitool method; the second path is used for rough and finish cutting both gears and pinions, using the standard generating roll. Variable rate-of-roll cams can be provided for increased cycle efficiency (at some cost in versatility) in high pro duction situations. When production is high enough to justify separate pinion machines for finishing the drive and coast sides, a further refinement is pos sible; the machine can be equipped to cut on the up-roll only, or the down-roll only, depending on which side ol the pinion tooth it will cut In such cases, the stresses on the machine, cutter and work are always in the most favorable direction for quality and long life. The cutter spindle adjustments have been designed to provide universal cut ter tilt (30 in all directions), at the same time giving maximum rigidity to the spindle mounting. The cutter center does not move when the cutter axis is tilted, as shown in the diagram on oppo site page. This tilt takes place about an axis which intersects the cutter axis and lies in the plane of the blade points. This results in simplified calculations and fewer adjustments when position or shape changes in the tooth contact are made. All moving parts on this machine are fully enclosed and automatically lubri cated. Automatic safety features are provided wherever necessary. Push button stations are suitably located so that the machine can be controlled from various operating positions. Operation I A circular face-mill type cutter is used on the No. 432 Hypoid Generator as shown. The tooth profile shape is produced by the generating method in which a relative rolling motion takes place be tween the gear and the rotating cutter. The action is as though the gear being cut were rolling with the mating crown gear of which the cutter represents a tooth. Once the gear is chucked in the work head, the machine operation is entirely automatic. With the machine arranged for gen erated roll cutting, the feed cam moves the work head and gear into cutting position. The cradle on which the cutter is mounted then rolls in timed relation ship with the work spindle to generate a tooth space. At the completion of one tooth space, the cradle and work reverse direction, the work is withdrawn and indexing takes place. The work head oves forward and the sequence of .notions is repeated until every tooth has been cut The machine stops automati cally when the work is finished. The special high production cams produce the same sequence of motions, except that the rate of roll varies so that the blades remove equal amounts of stock during all portions of the generat ing roll. When the straight infeed path is employed, the rolling motion of the gear and cradle is locked and the tooth space is cut by a depth feed of the work directly into the cutter. After each tooth space is cut the work is withdrawn and and the gear blank is indexed to the next tooth space. This sequence of motion is repeated until the gear is finished.
