Precision Grinding of Hard and Brittle Materials Two cup-shapedidentical size diamond-grindingwheels with metallic (D20/30 MIC­ L50M-l/4) and resinoid (SD240-RIOOB69-6mm) bonding were used. The profile of the grinding edge is circular in this case, but not restricted to this shape, thus forming a toroid.

Wheel grade indicates the grinding wheel's bond strength in retaining the abrasive grits during cutting. This is largely dependent on the amount of bonding material present in the wheel structure. The grade is measured on a scale that ranges between soft and hard. Soft wheels lose grains readily, whereas hard wheels retain their abrasive grains.
