Abstract

A grinding machine adapted for grinding surfaces of thin workpieces comprises a rotating table provided with at least a workpiece holder on which a workpiece to be ground is held, and a plurality of grinding wheels having different grain sizes ranging from coarse to fine, and rotating independently of each other. The wheels are disposed above the table and in arrangement so that, as the table rotates, the wheels grind successively the surface of the workpiece to provide a desired total thickness of grind and a reasonable surface finish through one rotation of the table.
