METHOD FOR PRODUCING METAL-BONDED GRINDSTONE

摘要

A method for producing a metal-bonded grindstone comprising abrasive grains as the grinding material, cobalt, ceramic, and a binder comprises: a heat treatment step for obtaining a baked product by baking a material formed from the abrasive grains, cobalt, ceramic, and the binder in a compressed inert gas atmosphere while pressure is applied to the material by means of hot pressing; and a cold treatment step for obtaining a grindstone by stopping the heat treatment and cooling the baked product while the pressure of the compressed inert gas is maintained.
