This research is focus on electrolytic composite polishing combining with electro-polishing and mechanical polishing to optimize the surface roughness of stainless steel and the wear rate of bamboo carbon electrode. Bamboo carbons’ microstructure are comparatively porous and dense, its micro-pores possess high adsorption capacity. In this article, we expect bamboo carbon could enhance the additional values by combing with existing industrial technologies. The electrolytic composite polishing in this article are experimented with the parameters of machining time, abrasive, increasing load, concentration of abrasive, polishing plate speed, electrode speed and voltage of electrolytic composite polishing. And the roughness of stainless steel, the wear rate of bamboo carbon electrode and the surface morphology of the results are investigated and analyzed.
