Abrasive grinding wheels are widely used in industry for the roughing and surface finishing of components through a chip-removal process [1,2]. This requires very high ... [16]. Utilizing texturized grinding wheels with straight and spiral type grooves reduced surface roughness by 4–5 times for Cu, 1.5 times for brass, and 3 times for Al6061Web
In general terms, the abrasive grit size range for grinding wheels runs between 12 grit for rough grinding operations, such as those found in steel mills, and 220 grit for very fine/precision grinding operations. Again, there is no industry standard, but in general terms: Coarse grits run 12 to 24. Medium grits run 30 to 70.Web
The type of material used as the abrasive grain depends on the hardness of the material that it grinds. This includes aluminum oxide, silicon carbide, ceramic, diamond, and cubic boron nitride.
