cnc punch

CNC punching A HACO CNC punching machine Punched hole: best results for cutting surface with above 70% cutting, low clearance necessary (8% material thickness) Punch presses are developed for high flexibility and efficient processing of metal stampings. The main areas of application are for small and medium runs. Those machines are typically equipped with a linear die carrier (tool carrier) and quick change tools. Today the method is used where the application of lasers are inefficient or technically impractical. Principle of operation After programming the work pieces and entering length of bars the control automatically calculates the maximum number of pieces to be punched (for example 18 pieces of a bar of 6000 mm). Once the desired number of work pieces is entered, the bar is pushed toward the stop. The machine is fully automated once the production process is launched. The third CNC axis always moves the cylinder exactly over the tool, which keeps the wear on the
