Abstract
PURPOSE:To enable the grinding machine to make a surface grinding of a workpiece loaded on upper surfaces of grinding wheels with greater accuracy by the rotation of these grinding wheels by eccentrically holding each mounting center of these ring grinding wheels apart from each center of rotation of mounting plates, and making the centers of the ring grinding wheels movable by rotating the mounting plates. CONSTITUTION:Three mounting plates 5 are rotated around their centers O2 respectively at the same angle and in the same direction in accordance with the outside dimensions of a workpiece by turning a control handle 17. By turning the control handle, centers O3 of three ring grinding wheels 9 eccentrically arranged apart from the centers O2 of the mounting plates 5 are displaced relative to a shaft center O1 of a vertical central shaft P so that the centers O2 are located on the apexes of an equilateral triangle, and a grinding operation of the workpiece is set to a good condition. After the workpiece is loaded over the three ring grinding wheel 9, the workpiece can be surfaceground by the ring grinding wheels with greater accuracy by rotating these grinding wheels 9 around their centers O2 in the same direction and at the same angle by a motor.
