Grinding tools are made of carbide abrasive grains such as those coated by electrodeposition, and a typical electrodeposition method is nickel plating. A grinding tool produced by this plating method is constructed as shown in FIG. That is, a nickel layer 13 as a bonding material layer is formed on the surface of the base metal 11 by electroplating or chemical plating, and at the same time a large number of cemented carbide abrasive grains 14 are held. By the way, in order to improve the grinding performance of such a grinding tool, it is important to sufficiently retain the abrasive grains 14 without falling off. With the holding force of grain 14, it is still abrasive grain 14.
The nickel layer 13 frequently falls off and the nickel layer 13 peels off, and a fully satisfactory tool life is not obtained.

る。The grinding tool according to the present invention solves the problems of the prior art,
It has the following configuration to achieve the purpose. That is, a nickel coating layer was formed on the base metal by a vapor deposition method (including a chemical vapor deposition method and a physical vapor deposition method), and superhard abrasive grains such as diamond or CBN were electrodeposited on the coating layer by a nickel plating method. An abrasive layer is formed. Preferably, the nickel coating layer is formed as a first nickel coating layer, and the abrasive grain layer is formed by temporarily adhering carbide abrasive grains onto the first nickel coating layer by a nickel plating method, and then further depositing them by vapor deposition. A second nickel coating layer is formed by a method.

力が得られる。According to the grinding tool of the present invention, the nickel coating layer formed by vapor deposition has stronger adhesion or bonding force to the base metal than the nickel layer formed by plating, and Strongly prevents peeling from gold. Since the coating layer formed by vapor deposition and the plating layer are made of the same pure metal, their affinity is very good, and an extremely strong bonding force is obtained between them. In addition, when a second nickel coating layer is formed on the plating layer by vapor deposition, the abrasive grains become even stronger due to the strong bonding force between the second nickel coating layer and the plating layer and the strong holding power of the coating layer. Retained. Incidentally, vapor deposition methods include chemical vapor deposition method and physical vapor deposition method, and in either case, a stronger bonding force can be obtained than the electrodeposition method using plating.
