The tungsten carbide worm gear hob is typically used in turbine machining and its machining method is almost the same as that of the gear hob. What differentiates them is that during worm gear hob machining, the helix angle is not being moved while gear hob does. Because of this, when the worm gear hob with a large helix performs its machining, its clearance angle tends to be touched easily, making the machining become more difficult, so does its production.

The differences between tungsten carbide worm gear hob production and that of the gear hob are mainly as follows:

I. Reference circle requirements in worm gear hob production;

II. Tooth shape difference;

III. The helix angle is not being moved during worm gear hob machining, therefore, the axial pitch of worm gear hobs is just equal to that of gear hobs.
