This report deals with the truing characteristics of metal bond CBN wheel by feeding a multipoint diamond truer and the influence of the truing on the wheel performance. The ratio of actual to setting truing depth of cut for metal bond CBN wheel is larger than resin bond one because of the higher elastic modulus of metal bond. The truing process of metal bond CBN wheel as well as resin bond one is classified into four stages. Until the middle of the second stage, truing force is low because of little truing of bond, and the wheel performance is kept well from the view point of the ratio of the actual to setting depth of cut, grinding force and temperature, and surface roughness. From about the middle of the second stage, the trued bond increases and begins to attach the cutting edges and the bond. As a result, as truing process proceeds, the truing characteristics and the wheel performance become worse. Then, dressing is necessary for large total truing depth of cut before the truing process enters into the middle of second stage.
