YNCP Series


High clamping torque

Air hydraulic clamping mechanism gives high clamping torque.

Rigid bearing structure

Since the table shaft is supported by large bearings, displacement by load will be smallest. Centering of jig/work piece is easy.

Accurate indexing

Accurate indexing is available by durable worm wheel of special alloy. Indexing accuracy of YNCP250 is within 20 seconds cumulatively.
