Abstract

PURPOSE: To prevent stripping of grindstone layer and thereby to provide grindstones with grinding layer firmly bonded to base, by forming an intermediate layer with coefficient of linear expansion at normal temperature larger than that of the base but smaller than that of the grinding layer, between the base and the grinding layer.
CONSTITUTION: Intermediate layer 8 containing iron, copper and tin is formed between iron base 1 and grinding layer 9 consisting of cubic boron nitride or diamond grindstone bonded by a copper-base bonding sgent. By setting the coefficient of linear expansion of the intermediate layer 8 larger than that of the above described base 1 and smaller than that of the above-described grinding layer 9, base 1 and grinding layer 9 are bonded firmly.
