The NIKKEN CNC401 uses hydraulic clamping for a clamping torque of 1760Nm with an average of 16.6RPM. 

The CNC401, like all NIKKEN CNC Rotary Tables, offers unrivalled high precision, high rigidity and durability.

With hydraulic clamping, this rotary table is used by many on their medium machining centres to deliver fourth axis capabilities.

This difference between the CNC401 and the CNC401T is the motor is mounted to the top of the rotary table. We also offer left or right-hand mounted motors, CNC401, or back mounted motors, CNC401B. High-speed motors are also available for the CNC401 and CNC401B. 

The rotary table can be supplied with a range of motors and controllers to meet your specific requirements - see the downloads section for more information or contact us to learn more.
