A trend of hydraulic control system of NC punching machine was going to digitization,so a hydraulic control system of NC punching machine was proposed based on 2D high frequency digital valve. The work principle and control principle were analyzed. It is shown that the output force,the frequency and the displacement of the cylinder in the hydraulic control system are controllable. Specifically,the displacement is continuously control. The parameters of the hydraulic control system were also calculated.
