Experimental Study of Grinding Performance of Chemical Permeated Grinding Wheel

Grinding process with grinding wheel can generate large amount of heat,which easily lead to burn,make micro-cracks on workpiece surface.For the purpose of reducing the grinding temperature,a sort of chemical permeated grinding wheel has been developed.The chemical permeated grinding wheel is a new kind of grinding wheel,which is permeated by the chemical additives and solid lubricant into the gaps of the grinding wheel's interior.Therefore,the grinding wheel can form lubrication film on the surface of the gaps with effective cooling and lubrication.This grinding wheel has some good features,such as lower grinding temperature,smaller grinding force,higher life of the grinding wheel,and can prevent the adhesion of chip onto the grinding wheel surface.The experimental results show that the ground surface quality and grinding efficiency have been remarkably improved for hard-to-cut materials.[Ch,5 fig.2 tab.13 ref.]
