Gear Honing

Gear Honing is a hard finishing method. It is applied to eliminate gear errors after the process of hardening. It also smooths the surface of a gear teeth. Honing is also known by another name that is "Shave Grinding". In terms of machining kinematics or even the tool geometry it is quite similar to gear shaving.

A common fallacy associated with honing is that it cannot better the profile error, lead error etc., inherited from earlier machining and the distortions that results from the hardening. This is not a correct thinking. Modern and sophisticated gear honing (shave girding) machines easily removes considerable amount of materials to rectify the gear errors.

Advantages of Gear Honing
The gear honing process offers the following advantages:

Gear Honing Machine
Gear honing machine is used for the finish machining of the tooth flanks of hardened gears. It is well suited for honing high-volume automotive gears. Its use in the honing process generates a high quality, final tooth geometry on hardened gears, while improving surface roughness and structure.
