GPH-20 Series
The independent handwheels that can be operated as a manual machine are mounted to X-axis (wheelhead infeed) and Z-axis (table traverse) of GPL-20 series. Furthermore, the use of the electronics table stopper for table positioning arrayed on the apron achieves both quick operation outperforming a manual machine in a single workpiece grinding and highly-efficient grinding combined auto-functions of NC operation in lot producition.
The CNC cylindrical grinder provides simultaneous 2-axis control of the wheelhead (X-axis) and table traverse (Z-axis).
