Hobbing

8,000rpm■ Gear machining processes (skiving, hobbing, lathe, drilling) areintegrated into one machine.
■ Optimal capability for small workpiece.
(outer diameter: up to φ100mm, full length: up to 300mm)■ Enhanced lathe function with optimal axis composition,
special cutting tool, and program.
■ Installation ﬂoor space comparison: 54%-reduced with machining lineof lathe, drilling and gear cutting.
■ High accurate machining for free curved surface is possible
with high rigidity and by multi-axis synchronizing control.
