| 摘要 |
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 ).
