ABSTRACT:
Disclosed is a method of producing a grinding wheel by electroplating. A part of the outer peripheral portion of a grinding wheel body is immersed in a plating solution. While rotating the grinding wheel body at a low speed, electric current is supplied to flow between an anode disposed in the plating solution and a cathode contacting the grinding wheel body, so that a pre-plating layer of uniform thickness is formed on the outer peripheral surface of the grinding wheel body. Plating operation is continued while adhering abrasive grains to the pre-plating layer to further cause a precipitation of a plating layer to temporarily fix the abrasive grains. The abrasive grains are then pressed by a pressing roller so as to be forcibly embedded into the pre-plating layer by making an effective use of plastic deformation of the pre-plating layer, thereby to obtain a uniform projection height of the abrasive grains from the surface of the grinding wheel. Then, a final plating is conducted to finally fix the abrasive grains. Disclosed also is an apparatus suitable for use in carrying out this method.
