MR/MRN series

CNC machine model to realize energy-saving/space-saving, and support the efficiency of production line by high speed operation.

To adopt ball screw for spindle reciprocating, and achieve high speed change by servo motor.
To realize the high accuracy/high speed machining and the energy saving/space saving together, with many useful function.
