Zusammenfassung:	A cylindrical grinding machine truing and dressing device for refinishing the surface of a peripheral grinding wheel (15) of a cylindrical grinder (10) comprises support base (12) attached to the work bed (11) of the cylindrical grinder, a housing (26) mounted on the base and rotatably supporting a rotatable truing tool (22) driven by a motor (30). The device further includes a slidably housed dressing bar (35) and abrasive block (36), a stepping motor (40) to axially displace the dressing bar and abrasive block, and a worm gear (42) for translating the stepping motor rotation into dressing bar axial' displacement, the axial displacement being precisely controlled to forcefully engage the grinding wheel before, during and after the truing operation.
