When you install a new grinding wheel on a bench grinder or encounter a heavily used wheel, the wheel will vibrate and have an uneven grinding face. Truing the face of a bench grinding wheel requires a grinding wheel dressing stick. A dressing stick has a harder composition than the grinding wheel. When you apply a dressing stick to the grinding wheel, the grinding wheel wears down. This exposes a fresh grinding surface and squares the face of the wheel.
