GRINDING WHEEL AND ITS MANUFACTURING METHOD

PROBLEM TO BE SOLVED: To certainly establish a self-regeneration effect of a cutting edge and promote formation of a chip pocket in association therewith even if a grinding wheel is structured so that the abrasive grains are held by a metal plating phase, maintain stably the cutting sharpness and grinding efficiency, and preclude an increase in the resistance, breakage of the grinding stone, a deterioration in accuracy of the grinding surface, etc. SOLUTION: Particles 6 finer than the abrasive grains 4 are bound together by a binding agent 7 to generate granulated substance, and an abrasive grain layer 2 is formed by dispersing this granulated substance together with abrasive grains 4 as a filler 5 in a plating liquid and depositing the metal plating phase 3. Thereby the grinding wheel 1 having the abrasive grain layer 2 in which the abrasive grains 4 and the filler 5 are dispersed in the metal plating phase 3, is produced, including the filler 5 consisting of the granulated substance formed by binding the particles 6 finer than the abrasive grains 4 using the binding agent 7.
