How grinding wheel is made material, history, used

Abrasive grains constitute the central component of any grinding wheel, and the hardness and friability of the grinding materials will significantly affect the behavior of a given wheel. Hardness is measured in terms of a relative scale developed in 1812 by a German mineralogist named Friedrich Mohs.

White fused aluminum oxide holds its form well. It is used to grind heat sensitive alloys. These applications make use of its friability and the fact that it cuts without generating high heat. This grain is also used to gring heat treated tool steels, high speed steels, and for internal grinding wheels.

Why Diamond Grinding Wheels Are Super Abrasives

Why Diamond Grinding Wheels Are Super Abrasives

Another area that requires attention when manufacturing a diamond grinding wheel is friability. Abrasives are selected depending on their friability and the nature of the material that needs to be ground. Diamond may be the hardest material but it reacts with steel when cutting.
