Tungsten Carbide Hob (2)

Tungsten carbide hob is a cutting tool with a series helical carbide teeth used for hobbing during the gear cutting, splines or sprockets cutting processes.

The cross-sectional shape of the hob teeth are used with the finished products, which has the same shape as teeth of a rack gear. Some light changes are made, with the consideration of the shape for generating purposes, such as extending the hob's tooth length to create a clearance in the gear's roots.Each hob tooth is relieved on the back side to reduce friction.



Compared to the popular single-thread hobs, but double and triple-thread hobs present ability in increasing production rates. The shortcoming is, when taking accuracy into account , they are poorer than single-thread hobs.Depending on type of gear teeth to be cut, there are custom made hobs and general purpose hobs. Custom made hobs are different from other hobs as they are suited to make gears with modified tooth profile. The tooth profile is modified to add strength and reduce size and gear noise.
