ABSTRACT:
A rotor is formed by rotationally cutting a metal mass mounted on a machine tool shaft under computer control, and also its outer periphery is formed with annular grooves by rotational cutting. The rotor is rotated on a shaft while feeding an abrasive to it, while a workpiece set on a stage movable along three perpendicular axes, i.e., X-, Y and Z-axes, urged against the rotor by moving the stage in the Z-axis direction. The surface of the workpiece is polished by causing the stage to be moved in the X-axis direction and reciprocated in the Y-axis direction, the urging pressure being controlled by measuring it with a pressure sensor.
