Regardless of the grinding wheel, though, all grinding processes use abrasive particles to "grind" away material from a workpiece's surface. When a workpiece is exposed to a grinding wheel, some of its material will rub off. With that said, grinding is often used to both remove material from workpieces as well as polish workpieces.
