Gear hobbing machine

Gear hobbing machines are the most widely used type of gear processing machine tools. They can cut spur and helical cylindrical gears, as well as worm gears and sprockets. These machines use a hob to generate spur, helical, and herringbone gears, as well as worm gears. Using specialized hobs, these machines can also process workpieces with various special tooth shapes, such as splines and sprockets.
