Another characteristic of worm manufacturing is the need of specialized machine for gear cutting and tooth grinding of worms. The worm gear, on the other hand, may be made with the hobbing machine used for spur gears.
The result of cutting a worm wheel with a hob that is smaller than the worm is that, in use, the worm would only contact the worm wheel at the outer edges of the teeth. Hobs for cutting worm wheels are designed to be larger than the worms by an amount that allows a number of resharpenings before the hob has to be replaced.
