Gear Hobbing Machine
Gear hobbing machine is the most widely used machine tool in gear processing machines.
It can cut spur gears, helical gears, and worm gears and sprockets. A gear processing machine for machining straight, helical and herringbone spur gears and worm gears by means of a hob.
This machine can also process various special toothed workpieces such as splines and sprockets when using a special hob.
