CNC busbar punching cutting machine The machine can complete various processing techniques of punching hols(round holes, long round holes etc), embossing, cutting, slotting, cutting round corners etc. The machine can automatically process copper with 3mm thickness and 15mm width. The hydraulic main and assistant double clamp and the clamp can automatically change. That can provide the machining precision and work efficiency. Automatic draging(push material) system can push off the finished workpieces. Large die library, cutting surface is smooth without indentation. Die material is high performance alloy steel mold, quenching process is advanced, the processing level is high and long service life.
