The NIKKEN CNC321 uses hydraulic clamping for a clamping torque of 1760Nm with an average of 22.2RPM. 

This difference between the CNC321 and the CNC321B is the motor is mounted to the backside of the rotary table rather than the left or right, making it perfect for machines that don't have ample space for the Y axis. 

The CNCZ321 comes with a high-speed motor as standard that can quickly deliver a substantial return on investment.

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.
