The shape of cutting edges on a wheel surface is an important factor which affects the grinding characteristics. We investigate the shape of cutting edges on the surface of a resinoid-bonded CBN wheel just after truing with a rotary diamond dresser, and its influence on the grinding force, wheel wear and surface roughness. Through stereo-SEM observation of the wheel surface, the following results are obtained. (1) In an up-cut truing operation where the rotation speed of the CBN wheel and the dresser is negative bond material and CBN grains are removed at the same time. Therefore, the operation shows a high truing performance, and results in a large flat area on the individual CBN grains. In the next dressing operation, the layer which contains the flattened CBN grains has to be removed to obtain a better grinding result. (2) In a down-cut truing operation where the rotation speed ratio is positive, CBN grains are crushed and fractured on a large scale, or released from the bond surface. Therefore, in a down-cut operation precise truing is impossible.
