摘　　要：脉冲电化学光整加工技术是近年来发展起来的非接触式光整加工技术，为此对其进行了研究，并成功实现了碳钢圆柱体表面上的脉冲电化学光整加工．研究表明：脉冲电流密度、脉冲频率、电极相对运动速度及极间间隙对光整效果有显著影响．该工艺可将Ra=0．217～1．13μm的磨削表面光整成Ra=0．041μm的表面．光整后，试件直径减小20～30μm，圆度误差平均降低5．13μm，圆柱度误差平均降低11.36μm.Pulse electrochemical finishing technology is a kind of non-contact finishing technology, which is developed in recent years. The finishing of carbon steel by the technology is studied and it comes true on column surface. The study shows that pulse current density, pulse frequency, relative velocity of the electrodes as well as the inter-electrode gap affect the finishing results greatly. The finishing technique could reduce the ground surface roughness from Ra= 0. 217-1.13 μm to R, = 0. 041μm. The diameters decrease 20-30μm after being finished. The roundness errors decrease about 5. 13μm and the cylindricity errors decrease about 11.36μm.
