External grinding method for cylindrical pin

摘要

The method is for external round-grinding of cylindrical pins, both the workpiece spindle and the grinder disc being rotated at set speeds. The disc has a dressed external cylindrical surface. During dressing, feed takes place for between 0.05 and 0.15 mm per revolution of the disc, and/or as the desired rotational speeds of disc and work are approached, the speed of the disc and/or work under load is continuously varied within a predetermined range, so as to maintain the maximum disharmony between the two, i.e. a ratio between the two which is a whole number or a simple fraction is avoided.
