The original hydraulic profiling machine is transformed into QX63-30OCNC three rollers power spinning ma- chine. Mainly study the characteristic of longitudinal hydraulic servo system to the CNC spinning machine. Firstly, deter- mine the mathematical model of the longitudinal servo cylinder. Secondly, determine the NC system with PMAC internal PID algorithm, and through the Simulink simulation software analyze the PID controller parameters on the influence of the hydraulic servo system feature. Finally, according to the results of simulation and debugging of the spinning machine NC system with PMAC parameter, make the longitudinal hydraulic servo system response time and positioning accuracy im- proved, and satisfy the requirement of technical indicators of CNC spinning machine.
