dtr newly developed carbibe hobs can cut gears down powerfully at high speed which brings higher effeciency. of production than conventional hss hobbing. charcterstics: 1.high cutting speed 2.short machining speed. 3.a longer tool life than conventional hss cutters. 4.time saving  per price for gear manufacture. 5.high

the teeth and body are assembled separately and with different materials. advantages:- 1.the cutting control is efficient controlled relief life. 2.cost effective with lower material price for body. 3.useful for high speed cutting with controlled arbor. disadvantages:- 1.the manufacturing process is complex 2.the out-parameter

increasing productivity:special hss and multi layer coating increasing cutting ability more than 2 times compared to convential hob. cost savings:increase tool life and reduced cycle time lead to cost saving efficiencly. friendly to environment:production without cutting oil. sucessful results require:need a good bobbing m/c for turbo

Traditionally, profile and lead inspections have been indispensable portions of a standard inspection of an involute gear. This also holds true for the worm of a worm gear drive (Ref. 1). But the inspection of the profile and the lead is rarely performed on a worm wheel. One of the main reasons is our inability to make good definitions of these

a worm is designed based on worm shaft specifications.their are no standards for worm gear specifications. generally hob is manufactured as zk type. Gleason Cutting Tools Corporation makes all types of HSS hobs for throated worm gears which mate with non-enveloping worms: single or multiple-thread, shell, shank or clutch-driven, topping or

Splines are ridges or teeth on a drive shaft that mesh with grooves in a mating piece and transfer torque to it, maintaining the angular correspondence between them.spinner gear is used when the power transmission is same direction For instance, a gear mounted on a shaft might use a male spline on the

A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear.[1] Two or more gears working in a

Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets on a hobbing machine, which is a special type of milling machine. The teeth or splines are progressively cut into the workpiece by a series of cuts made by a cutting tool called a hob. Compared to
