ABSTRACT:
A dressing apparatus for dressing an electroplated grinding wheel by crushing the top portions of the abrasive grains thereof. The abrasive grains are diamond grains or CBN grains. A role made of ceramics, or a ferrous role holding diamond grains on its outer periphery is used for crushing the abrasive grains. The grinding wheel is rotated in one direction and the role is rotated in the opposite direction so that the difference in surface speed between the role and the grinding wheel becomes substantially zero. The role is then advanced toward the grinding wheel to crush the top portions of the abrasive grains, so that the heights of the abrasive grains are roughly equalized, and many sharp cutting edges are formed at the top portions of the abrasive grains.
