The development trend of CNC punch press is to use hydraulic power system instead of mechanical power system. In this paper, a new hydraulic power system developed by author recently is introduced. The rapid advance and return movement of the hydraulic cylinder is achieved by using rapid on-off valves as the forerunner valves to control the massive flow, so that the CNC press can drive the slider and the mould rapidly with great power. After being improved, it runs well with simple structure and low cost. It is as good as that of the imported machine and may be used as a substitute.
