【Abstract】 The precision mirror surface grinding of steel bonded cemented carbide has been carried out using the combination of ELID and iron bonded diamond wheel. The grinding mechanism of steel bonded cemented carbide with the out of phase inhomogeneous was analyzed. The result of atomic force microscopy (AFM) show that the precision mirror surface grinding of the part made in steel bonded cemented carbides has been resolved by using the ELID grinding. The surface roughness produced by ELID grinding is less or equal 20nm in Ra.更多还原
