Abstract

PROBLEM TO BE SOLVED: To provide a method and a device for stably supporting a work piece when a thin work piece is applied to a grinding machine provided with a double-end grinding wheel capable of simultaneously grinding both surfaces of the thin work piece while rotating it. SOLUTION: A thin work piece supporting member is provided on the inner side of a double-end grinding wheel peripheral surface of a grinding device provided with a double-end grinding wheel. Since the thin work piece supporting member is provided on the inner side of the double-end grinding wheel peripheral surface, the thin work piece supporting member can be fixed to a fixing shaft for fixing the double-end grinding wheel (a straight cup grinding wheel 11). This thin work piece supporting member supports the side, the outer periphery of a thin work piece 12 or both the side and the outer periphery. For instance, when the thin work piece 12 is applied to the grinding device provided with the double-end grinding wheel, the outer periphery of the thin work piece 12 is supported on a work piece carrier 14 held in a fixed carrier guide 15, and the side and/or the outer periphery of the thin work piece 12 is supported by an inner side supporting member 18 provided on the inner side of the double-end grinding wheel peripheral surface.
