A method for the purpose of dressing a grinding wheel and sharpen

摘要

The grinding wheel is first dressed by a dressing tool and is thereupon sharpened or finished by particulate material which is introduced into a gap between its working surface and a pressure applying roll. The latter is thereupon ground by the grinding wheel. The controls of the grinding machine are used to feed the grinding wheel toward the dressing tool and the roll to different extents in order to compensate for the fact or possibility that the wear upon the roll during finishing is or can be more pronounced than the wear upon the dressing tool during dressing of the grinding wheel. This also ensures that the width of the gap can be maintained at a given value during each of several successive finishing operations.
