GC3150J Series

Gear Hobbing Machine - GC3120J / GC3132J / GC3150J

FEATURES:
The model GC series are Gear-Hobbing Machines desighed for cutting cylindrical straight gears. Cylindrical helical gears and worm wheels. With the hob tooth profile modified, the machines are capable of cutting sprocket wheels or components with other tooth profiles.
The machines feature in high rigidity, constant working accuracy and easy-to-maintain. The machines complete the gear-cutting operation automaticaily either by the climb hobbing method or by the conventional hobbing method. These machines are well-suisted for the job-lot, the small batch or the mass production of gears in various industries.
