The open tilting CNC punch press adopts a rigid rotary clutch, which has single and continuous operation specifications, uses a belt brake, and the slider is equipped with a collapse type safety device. When overloaded, the safety device will collapse to ensure that the whole machine is not damaged. As a tilting casting structure, it is easy for stamping parts or waste materials to slide down from the mold when tilted. This punching machine has the advantages of strong universality, high precision, reliable performance, and easy operation. It can be equipped with an automatic feeding device to achieve semi-automatic stamping operations.
