Studies on the Truing and Dressing of Diamond Wheels-Truing Principles of GC cup Truer

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