PURPOSE:To prevent abrasive grains in a plated layer from being removed so as to prolong the life of the grinding stone, by coating a carbide blank with a titanium compound, and applying a plating thereon, so that the adhesion between the carbide and the plating is increased. CONSTITUTION:The blank 9 includes a shank section and a shaft section smaller in the diameter than that of the shank section, and is coated with a titanium compound such as tungsten carbide, titanium carbide etc. The titanium compound 12 is applied by a chemical deposition method or physical deposition method, and the adhesion of the titanium compound with the carbide such as tungsten carbide, etc. is excellent. An insulating coat 13 arranged on part of the blank 9 is for electrodepositing abrasive grains such as grains of diamond only on the tip of the blank 9. Thus the plated layer is prevented from being removed and the life of the grinding stone can be prolonged. |
