The polishing techniques now include barrel polishing (mechanochemical polishing), mechanical polishing, chemical polishing, electropolishing and plasma polishing. Compared with plasma polishing, roller polishing (mechanical chemical polishing) and mechanical polishing take too long time, electrolytic polishing and chemical polishing not only have serious pollution, but also have poor polishing effect and high comprehensive cost, and plasma polishing not only has good polishing effect and high efficiency, but also has no pollution, so the application range is wider. The polishing principle of the plasma polishing machine is as follows: the workpiece is connected with an anode during polishing, the charged workpiece is immersed into a high-temperature plasma solution with negative charge, the applied voltage is 200-400V, a stable plasma layer appears on the surface of the workpiece, and the plasma layer separates the surface to be processed from the plasma aqueous solution, so that strong plasma chemical reaction and electrochemical reaction are generated between the surface of the workpiece and the steam of the plasma solution, cathode oxidation is generated on the surface to be processed, the cathode oxidation layer is chemically corroded, a polishing effect is generated when the oxidation speed is equivalent to the corrosion speed, and the glossiness of the surface of the workpiece is improved and the reflectivity is improved. After the surface of the workpiece to be polished is applied with high enough voltage, high electric field intensity is generated among the gas layer, the steam and the plasma liquid, so that the microscopic convex part on the surface is flattened, and the effects of deburring and polishing are achieved, wherein the polishing speed is increased along with the increase of an external electric field, and the polishing speed can reach about ten times of that of the traditional polishing method.
The traditional plasma polishing machine comprises a plasma tank which is filled with high-temperature and high-voltage plasma solution and is connected with a cathode, and a hanger which is electrically connected with an anode, wherein during polishing, the plasma tank is electrified, the front surface of a polishing workpiece is hung on the hanger and is electrified, the charged workpiece is soaked in the plasma tank for plasma polishing, after the front polishing of the workpiece is finished (the specific time is determined according to the actual condition), the hanger is pulled out of the plasma tank, the workpiece is taken down from the hanger, and after the hanger is hung on the back surface, the workpiece is soaked in the plasma tank again for plasma polishing, so that the back polishing is finished, the whole plasma polishing is finished, and because the plasma polishing speed is very high, the front workpiece needs to be pulled up and changed to the back surface for polishing continuously and repeatedly, the working efficiency is low.
