The cylindrical test workpieces were made from 0.5% carbon steel rod of hardness 52 HRc. Al2O3 vitrified bonded grinding wheels of three different hardness's (Grade J, K & M) were used having grain size 40 with a medium structure. It was concluded that the hardness of a grinding wheel is the most important property affecting the wear phenomena.

In the earlier studies, Stetiu and Lal [12], and Malkin and Cook [13] pointed out that there were three types of grinding wheel wear: attritious wear, grain fracture and bond fracture. In general, wheel wear is both physical and chemical, and their influence depends on grinding conditions and the specifics of a wheel–workpiece pair.
