Experimental Study on Cooling-Air Grinding of High Speed Steel

Abstract:

In the grinding of high speed steel, the high temperature grinding zone often leads to poor surface quality such as grinding burn, micro-cracks and tensile residual stresses. In the paper, the cooling-air technology was adopted to study the grinding of high speed steel. The experimental results show that cooling-air grinding can effectively restrain the grinding burns, reduce the surface roughness value and improve the surface quality in comparison with dry grinding.
