Grinding Wheel: Specifications & Manufacturing Process by Norton Abrasives

In grinding process, the process of breaking of abrasive grains & exposing sharp edges is called as friability. When the grains break down under pressure, the new edges for cutting emerge or are exposed. During this process, the binding material also gets removed and the grains which have become blunt get free and are removed.
