Plasma Electrolytic Polishing(PEP) is using the electrode as the negative electrode and the workpiece as the positive electrode , a plasma layer is formed on the workpiece and electrolyte by high voltage (the four-phase interaction of solid state, liquid state, gaseous state plasma of electrode, medium, gas layer, and electrolyte can achieve better surface roughness).
Equipment advantages: polishing metal surfaces, polishing metal parts with complex structures, cleaning seam welding, grind sharp edges, removing oxidation colors, scales and stains on the surface of materials.
