Abstract

PROBLEM TO BE SOLVED: To provide a method and a device to effect grinding and polishing with high precision and high efficiency, in a work needing the degree of flatness and parallelism of two end faces. SOLUTION: Two sets of work holding devices 8 to hold a work 2 are arranged symmetrically about the central axis of a cup type grinding wheel 1. Through arrangement stated above, a load in the direction of a machining axis exerted during grinding processing is exerted on the central shaft of the cup type grinding wheel 1, namely, the load is symmetrically applied on the main spindle 3. Therefore, since a bending moment on the main spindle 3 is generated, the work 2 is nipped between the two cup type grinding wheels 1 positioned facing each other, and the grinding working surface of the cup type grinding wheel 1 to effect grinding from the surface and the back keep parallelism with each other and flatten the ground surface of the work 2.
