Grinding Wheel Basics
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.

Sintered magnets receive some degree of machining which can range from grinding them smooth and parallel, OD or ID grinding, or slicing block magnets into smaller parts. The magnet material is both brittle and very hard (Rockwell C 57 to 61) and requires diamond wheels for slicing and diamond or special abrasive wheels for grinding.
