The punch press is also called "punch press". In the national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for the operator and making products that can not be achieved by mechanical processing through various mold applications, so it is more and more widely used. For example, we use switches, sockets, cups, cupboards, dishes, computer chassis, and even missile aircraft... There are a lot of accessories that can be produced by punch through mold.

There are many kinds of presses. According to the transmission structure, it is divided into manual punch, mechanical punch, hydraulic punch, pneumatic punch, high-speed mechanical punch and CNC punch. According to the processing accuracy can be divided into ordinary punch and professional precision punch. According to the scope of use: ordinary punch and special punch. According to the shape can be divided into open tilt, semi open, closed.

The cam controller is installed on the outside of the punch. According to the installation method of the cam controller, it can be divided into chain installation and synchronous pulley installation. The electronic cam controller can be used to realize the accurate acquisition, transmission and processing of punch angle, position, speed and other signals, whether it is chain type installation or synchronous belt wheel installation. DBS series rotary encoder is an indispensable signal detection sensor in electronic cam controller.
