High Clamping Torque NC Rotary Table GTM Series

Specification and Product data are available. CAD free download.

Increased clamping torque is achieved by increased piston area and new clamping mechanism.
Rigid Body Design allowing heavy machining. Improved Brake Piston design reduces distortion.
High Clamping Torque allows increased machining speed. Improved clamping speed redeuces takt time.
