High-speed abrasive flow composite polishing based on dielectrophoresis effect

The traditional abrasive flow composite polishing technology has the problems of long polishing time and low polishing efficiency. In order to solve this problem, a high-speed abrasive flow composite polishing method based on dielectrophoresis effect is proposed. This paper first studies the principle of dielectrophoretic polishing, understands the abrasive flow polishing process and the application of pulse jet polishing technology, then uses the mechanical principle of dielectrophoretic abrasive polishing to establish the friction and wear erosion model of single-layer abrasive and the material removal model of self-excited oscillation pulse abrasive flow polishing. Finally, the feasibility of this method is verified by high-speed abrasive flow observation experiment. The experimental results show that this method can effectively improve the adsorption weight of SiO2 abrasive particles, the abrasive particle removal efficiency is as high as 98%, and the polishing time of high-speed abrasive flow abrasive is only 9 s, which is better than the other two comparison methods. This method is effective for high-speed abrasive flow compound polishing and has certain application value.
