Numerical control punch can be used to process all kinds of sheet metal parts, and can automatically complete various complex passes and shallow drawing at the same time. According to the requirements, the holes with different sizes and different holes can be automatically processed, and the large round holes, square holes, waist holes and curve contours of various shapes can also be punched with small die, or processed with special technology. Such as blinds, shallow tension, drilling, flanging hole, reinforcement, relief, etc.). Compared with the traditional stamping process, the simple die combination can save a lot of die costs. It can process small batch and diversified products in a low cost and short cycle way. It has a large processing range and processing ability, and can adapt to the changes of market and products。

The die has the characteristics of complex structure, high precision requirement, high material hardness and short manufacturing cycle. Mold manufacturing is a complex production process, the production cycle is urgent, and the technical means are advanced. Each mold is a new project with different structural characteristics. Therefore, the technical level of mechanical processing put forward higher requirements. The traditional processing technology and equipment have some limitations, such as low processing level, low precision and long production cycle該，It directly affects the production efficiency and quality of the mold. The diversified development of NC machining technology, including NC milling, NC EDM, NC WEDM, NC turning, NC grinding and other NC machining methods, provides a wealth of production means for mold manufacturing. Among them, CNC milling machine and machining center are the most widely used, CNC wire cutting and CNC EDM are also very common in NC machining. It can be said that CNC machining technology is the core application of mold manufacturing technology。
