M7163

Modle:M7163

Brand: COSIS

Function
This machine adopts the periphery surface of the grinding wheel to grind surface of work piece. Vertical plane of work piece can be ground by the end face of the wheel. When ground, work piece is fixed on the electrical magnetic chuck or the table directly according to different ones.

The table moves longitudinally by hydraulic drive. The wheel head turns around transversely on the carriage either by hydraulic or by hand, and the device of automatic interlock is mounted. The carriage (together with the wheel head) moves vertically on the column either by hand or by mechanical operating, and an interlock device is mounted. The vertical ball screw, operated lightly and flexibly.
