The NIKKEN CNC321 uses hydraulic clamping for a clamping torque of 1760Nm and is ideal for the automation of small parts by mounting of jig holder. 

This difference between the CNC321 and the CNC321T is the motor is mounted to the top side of the rotary table. We supply the CNC321 with a motor mounted to the left or right-hand side, CNC321, or back mounted, CNC321B. Both with high-speed options available. 

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.
