Grinding performances of treated wheels are studied in order to clarify the grinding mechanism in various atmospheres. It should be considered that the frictional force plays an important role in a grinding process. The frictional force, Ff, and the coefficient of friction between wheel and work material, μ, can be decided by the experiments of surface grinding with several width of work material under the same condition. Besides, the index x which shows the percentage of normal force partly supported by the grains is able to calculate. According to these thinkings, the effects of treatments and several kinds of grinding fluids are estimated with μ, Ff/Ft, x, Ff and also with the grinding ratio and skin temperature. Small value of μ and small percentage of Ff in the appearent grinding force will be recognized in the treated wheel grinding which results the good performances equivalent to the wet grinding. Moreover, the grinding ratio becomes large in the treated wheels, it makes the wheel life be long.
