Features:
1. The machine is used for cutting all kinds of spline shafts with spur or helical gears, link shaft gears with spur or helical gears, tapered splines and stepped gears by hobbing.
2. It adops AC servo system to control longitudinal or transverse locating of hobbing head, change the actions, change hob speed (stepless), adjust hob automatically, and it can realize dry-hobbing, it features with good reliability and fine protection.
3. This is a high efficient machine for cutting splines and gears in batches or mass production, and it is suitable for mass or large batch production and suitable for make the automobile, tractors, shipping and mining machine or machine building industries etc.
