Abstract
A rotating dressing tool () coated with abrasive grains for profiling a multi-start grinding worm () for the continuous generation grinding of preferably small moduled gear teeth is provided with a stripping zone (), a pre-profiling zone () and a finish profiling zone (). After being swivelled into their dressing position about a swivel axis (F) at right angles to the axis of rotation of the dressing tool, the profiling zones are brought one after the other into engagement with the grinding worm (). The number of profile ribs in the pre-profiling zone and finish profiling zone is equal to or greater than the number of thread starts on the grinding worm.
