Abstract
A method of intermittently dressing the ring-shaped surface or active rim of an axially adjustable dished grinding wheel of a gear grinding machine and which active rim acts upon a workpiece. The position of the active rim is controlled and the grinding wheel adjusted such that the ring-shaped surface or active rim is retained at the same location independent of its wear. The active rim is dressed once within a predetermined dressing interval by means of a likewise axially advanced dressing tool. The dressing tool is then advanced if, within the dressing interval, the grinding disk adjustment or compensating feed has dropped below a predetermined total magnitude.
