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.
Internal Grinding
Grinding external, internal and end face in one clamping. Internal grinding oscillation axis enables the continuous machining from external to internal.As an optional feature, Internal contour grinding is available.
