According to the basic principle of the hydraulic-servo system, the mathematical model of the hydraulic-servo system of NC precision machine was build up by using the method of transfer function. Taking the software of Matlab/simulink as development tool, the dynamic performance of the system is totally analyzed, and a summarization of main factors affecting the dynamic performance of the hydraulic servo system is made. The dynamic performance of hydraulic servo system of NC precision straightening machine is optimized through dynamic analysis, and its working efficiency of the machine is improved effectively. Meanwhile it provides an accurate, convenient and efficient way to analyze the hydraulic-servo system of the NC precise straightening machine.
