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.
Can be equipped with internal grinding unit
By mounting internal grinding unit, NMGM-2HF enables external, internal and end face grinding in one clamping.
Other combination, outer diameter and internal diameter grinding is available.
