摘要：Aiming at the quality problems of over polishing and insufficient polishing in the process of traditional extrusion abrasive flow machining, An abrasive flow polishing method at the constantly small pressure difference is developed. The hydraulic proportional control system is designed, and the mathematical modeling of the hydraulic proportional control system for small pressure difference is set up, maintaining constant extrusion polishing in abrasive flow machining process. The simulation results show that the polishing pressure can be well controlled and the stability of polishing velocity is improved, which will improve the extrusion abrasive flow polishing quality. ?
