Abstract
A method serves for dressing grinding wheels (10) whose surface (16) comprises an embedding compound for CBN crystals. A rotating dressing roll (11) is moved along the surface (16) of the grinding wheel (10). In order to produce sharp-edged points at the CBN grains (20) during the dressing process, and obtain sufficiently large clear chip spaces in the embedding compound, the dressing roll (11) is moved over the said surface (16) at least twice, the first movement being carried out at a first, high rate of feed (v.sub.3) so that the dressing crystals of the said dressing roll (11) deflect the said CBN grains (20) elastically while setting back the embedding compound, whereas the second movement is carried out at a second, lower rate of feed (v.sub.4) so that the said dressing crystals break up the points of the said CBN grains (20).
