GT series

High clamping torque NC rotary table

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
