NR series

The model to achieve the machining of high speed & high accuracy by NC control for spindle reciprocating, and to suit the short stroke.

To drastically improve the efficiency of short stroke machining (Min. stroke 7mm) with Max. reciprocating times 450cpm.
To realize high accuracy honing by reducing impact and vibration on stroke change, and by controlling up-and-down motion with constant velocity.
