    摘要： This invention relates to a machine tool for dressing a grinding wheel with a concave profile. The wheel is rotated and is reciprocated axially, and a cutting tool is moved radially relative thereto under control of an eccentric cam. The eccentric cam is rocked under control of the relative movement of the grinding wheel and the tool support by means of a linear inclined cam, which is preferably of adjustable inclination, to control the depth of the concave profile. The dressed grinding wheel may be used in an automatically cycling grinding machine for forming track surfaces of convex profile on bearing outer race rings.
