Abstract

The invention relates to a grinding machine for grinding of a gear or of a gear-like workpiece, which has a grinding worm (1) with a tooth-shaped profile (2), which consists at least partly from a dressable abrasive material and which is arranged rotatably on a grinding spindle, so that it can rotate around an axis of rotation (C) during grinding and a dressing device (3), with which at least a part of the forming areas (4, 5) of the grinding worm (1) can be profiled, wherein the dressing device (3) has a dressing spindle (6), which bears a disk-shaped dressing tool (7), so that it can rotate around an axis of rotation (B). To allow a faster dressing of the grinding worm the invention is characterized in that the grinding machine further has a dressing bar (8) which has a dressing edge (9), wherein the form of the dressing edge (9) corresponds at least partly to the ideal envelope of the grinding worm (1).
