电解研磨精密加工

Electrolytic-abrasive Mirror-finishing

电解研磨精密加工方法是把电解加工和研磨加工结合起来,利用中性电解液,通以适当的电流密度,在磨料研磨和电解溶解共同作用下,对零件进行快速、高效的精密加工,使表面粗糙度可达到R_z0.01—0.02μm。这种加工方法适于一般碳钢,不锈钢,钛合金钢等零件的精密加工。本文阐述电解溶解和磨料研磨结合精密加工的效果,表面粗糙度形成机理和实验结果。

Using the electrolytic-abrasive mirror-finishing method,large workpieces of ordinary steel and hard process material,for example,stainless and titanium alloy steel,can be easily mirror -finished in a short time and with high efficiency,resuliting in a surface roughness of up to R,0.01-0.02m. This method is based on the fact that the electrolytic effect is assisted by the removel action of abrasive grains within an appropriate current density range by the use of neutral salt-type electrolyties. This paper clarifies the combined effects of the electrolytic dissolution and polishing action of abrasives. It also describes analysis of the surface roughness formation mechanism and the experimental resules.
