To improve the performance and broaching quality of broaching machine, according to the characteristics of electro?hy?draulic proportional servo valve, the major loop of horizontal broaching machine was designed based on the electro?hydraulic proportion?al servo valve volumetric speed control system. Through the way of electro?hydraulic proportional servo valve volumetric speed control mode, the control to broaching speed was realized. A closed loop control was formed using broaching speed as feedback, to inhibit the impacting in broaching process. The simulation model of the broaching machine hydraulic system was established by using AMESim software. Through simulation, it is verified that the system can effectively improve the stationarity of broaching process. The parameters of speed control system were optimized and the good simulation results were obtained. The results provide reference for application of the electro?hydraulic proportional servo valve controlled volumetric speed control system in hydraulic broaching machine.
