Each abrasive grain is a cutting edge. As the grain passes over the work piece it cuts a small chip, leaving a smooth, accurate surface. As each abrasive grain becomes dull, it breaks away from the bonding material. Types of abrasives. Two types of abrasives are used in grinding wheels: natural and manufactured.
