  • Grinding Wheel: Specifications & Manufacturing Process by ...

    While the grains are taking a cut in the metal of the job, the grains get crushed and break down due to the force acting on the wheel. 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.
