Simultaneous rough and finish grinding

NMGM-2HF is a highly efficient grinding machine with two external grinding wheels. Mounting two different grinding wheels at the same time, rough and finish grinding can be performed in one operation. As a consequence, an operator can save significant machining time.


Expand versatility and scalability with sophisticated CNC

NMGM-2HF is equipped with a FANUC control as a standard and our original interactive software, this machine reduces an operator's burden in complex shape machining.
