In the modern industrial production, the flat punching machine is the key equipment for processing all kinds of plate holes. The new forming technology is used to process the holes with high precision, accurate positioning and short production cycle, which replaces the traditional equipment.     With the development of high-tech, the application field of punching machine is more and more extensive. From the early national defense field and aerospace field, it has been extended to the fields of machinery and medical treatment. According to the shape of the material processed, the punching machine is divided into flat plate punching machine, round pipe punching machine, square tube punching machine and U-shaped steel punching machine. According to the needs of different industries, different parts and their thickness, the punching machine is designed Light, professional, bill and factory punching machines, such as enterprises and institutions of full-automatic professional punching machine, personal economic stapler, etc.; now in order to adapt to the trend of the times, to meet the needs of the market, punching machines are moving towards the direction of beauty and efficiency. < br style = "list style type: none;" / > & nbsp; & nbsp; as the punching machine has only less than 20 years from R & D to today, its development in China is only more than ten years. At present, there are still many imperfections and there is no unified industry standard, so there are more than ten kinds of names. < br style = "list style type: none;" / > & nbsp; & nbsp; the general accurate name is punch, CCD punch, many people call it target machine, Japan, Taiwan, Guangdong area are called perforator, perforator or puncher, and many people call them perforator and target punching machine. In fact, they all refer to the same product. According to the degree of automation, punching machine can be divided into manual punching machine, automatic positioning / positioning punching machine, automatic punching machine, etc. According to the different processing objects, it can be divided into soft plate punching machine and membrane switch punching machine.     Due to the wide application of punching machine, although the same production of punching machine, but the products of various manufacturers also have different focuses. For example, the punching machine produced by Xi'an feierda automation equipment company is mainly used for the enterprises producing circuit boards, circuit boards, printed boards, film boards and thin film switches, and the punching machines produced by some enterprises are mainly shoes or printing enterprises And so on. The price of punching machine generally only needs several thousand yuan, while the price of punching machine is about 20000 yuan at present. The main factor influencing the price of punching machine is punching precision, and the price of one wire (0.01 mm) will increase geometrically. At present, the positioning error (accuracy) of punching machines in the world is less than 0.015mm, and some domestic manufacturers have reached this level. < br style = "list style type: none;" / > & nbsp; & nbsp; the current punching machine can punch about 4000 holes per minute, which varies greatly according to the degree of automation.
