High clamping torque NC rotary table Kitagawa GT series
Description:
NC rotary table suitable for heavy machining
The very strong clamping torque was achieved by increased piston area and new clamping mechanism.
High clamping torque and rigid body allows heavy machining and shorter tact time.
Built-in rotary joint available
