This product is the special device to accomplish these works.1.This product has separate hydraulic power system and electrical CNC system, both of which are under centralized control.2.The body of the machine uses Type C double-plate jointing structure with the advantage of rigid, compact size, light weight and spacious operating space. The hydraulic system uses electromagnetic reversal valve as main device, which is assisted with some miniaturized system of cartridge units, its structure is simple and easy to use and maintenance.3.Biaxial CNC feeding worktable is connected with the main machine which can realize the precise positioning at random place of the working area and fulfill the working of punching, drilling and marking. Clamping of plate can help to position the original coordinate and relocate the place, which ensure the process precision of single work piece and the exchange ability of the same work piece.4.There are one working position of marking, two positions of punching and one position of drilling, which allows to the process of multiple specifications and apertures. Convenient dismantlement and accurate positioning enable to diminish the dwell time and mould adjustment time largely and to improve the work efficiency.
