Grinding wheel conditions are identified by observing the slope of the wear plot. Three grinding wheel conditions namely 'sharp-initial', 'intermediate-sharp' and 'worn out-dull' are shown in Fig. 2. In 'sharp-initial' condition, the metal removal rate is more than the wear rate of the abrasive wheel.

The bond is the substance that causes the abrasive grains to adhere to the wheel. Bonds can consist of different materials. Common materials include shellac, resinoids, rubber and glass or glass-ceramic. At Weiler Abrasives, our portable grinding wheels contain resinoid bonds. The bond on a grinding wheel may be either hard or soft.

Different grinding wheel conditions for the same grit sizes were studied. This was achieved by using different grinding wheel/truing speed ratios: these ratios have an influence on the surface condition of the wheel, as shown in Fig. 8. At a speed ratio of 0.5 with D46 grit size, the surface of the grinding wheel was found to be blunt.
