In the previous papers a new truing technique with the cup-truer was proposed for the preparation of diamond wheels. This paper describes the truing mechanism of diamond vitrified grinding wheels. The main results obtained are as follows : (1) The effect of truing with a cup-truer mainly depends on the impact of silicon carbide grains torn off from the truer against diamond abrasives and bond bridges. (2) The softer a cup-truer is, the larger grains will be torn off from the truer, leading to a higher truing rate and a rougher surface texture of the diamond wheel. (3) In truing with an impregnated diamond tool, which has almost no grains to be torn off, the grains sticking out most on the grinding wheel are removed in order. (4) In the early stage of grinding process, the protruding grains of silicon carbide filled as a filler in the vitrified bond are rapidly flattened. (5) For difficult-to-grind materials it is desirable to use a diamond vitrified wheel without a filler such as silicon carbide abrasives.
