In grinding operation, there are two important preparations, truing which forms wheel geometry and conditioning which generates chip pockets around abrasive grains on wheel surface. Truing has very strong influence on the performance of grinding wheel in terms of determining sharpness of grain cutting edges. In this study, truing of CBN wheel by PCD which has excellent wear resistance is attempted and correlations between truing force, grinding force and surface roughness are examined. Very sharp ridge end of PCD disk effectively reduces truing force and eliminate flexure of the quill of small diameter CBN wheels. Also, accuracy of sharpness control of grain cutting edges is improved compared to conventional truing tools.
