To set the height of the cutting edges of the tip ends of abrasive grains so as to produce a ground surface of a mirror finish level, and also to reduce the resistance in truing, and to make the truing of a thin abrasive wheel possible, and to prevent the metallic contamination due to truing.
A material containing silica glass as a main component is used as a truing tool. The heights of the cutting edges of abrasive grains are arranged by efficiently forming smooth flat portions on the tip ends of the abrasive grains on the surface of a bond by grinding the truing tool by a diamond wheel. The tip ends of the diamond grains wear by grinding the silica glass, and the tip ends of the projecting grains than the average height of the cutting edges are furthermore largely worn by deeply grinding the silica glass, and further the tip ends of the low grains have a small depth of cut, and their wear become small. As a result, the diamond wheels can be trued such that the heights of the cutting edges of the abrasive grains are uniformly arranged.
