The total removal of grinding wheel material includes two main parts. The larger of the two is the result of dressing and truing operation and the other relatively small part is due to the wheel wear which takes place during the actual grinding process. The frequency of dressing and truing operations depends on the cutting conditions, wheel characteristic, etc.

The best design for cutting hard materials, such as ceramic-coated superalloys, is a stiff machine that can dampen the vibration. Even a small amount of harmonics getting through to a ceramic workpiece can cause it to chip. "We dampen vibration by using hydrostatic guideways that are standard on the Mägerle grinders," says Marchand.
