Works air plasma cutting machine from the structure include: the main loop, the control loop and three gas path parts. (1) comprises a main circuit contactor KM, three-phase transformer B1, three-phase bridge rectifier (by D1 ~ D6, C1 ~ C6 composition), the high-frequency oscillator (by B2, B4, FP, C12 composition). (2) the control back to the routing control transformer B3 and J1, J2, J3, D7, C11, R3 and other components. (3) pneumatic solenoid valves in part by decompression and DF components. The principle is summarized as follows: connect the power and gas supply after closing the switch K1, XD power indicator light, cooling fan FM rotation immediately. Press the torch micro switch K3, relay J1 was electric action and its normally open contact connected, the solenoid valve DF action CNC laser cutting machine, gas is turned on, the torch pre-ventilation. 1. The structure of the machine frame is welded structure CNC cutting machine maintenance, solid and reasonable, simple, durable. 2. Cutting speed, high precision. Cutting mouth is small, neat, no dregs phenomenon. On the basis of the traditional numerical control system based on improved cutting control, avoiding the secondary finishing processes. 3. For a low-carbon steel, copper, iron, aluminum, galvanized sheet, titanium plates and other metal plate. 4. CNC system configuration is high. CNC automatic arc cutting machine software, stable performance, igniting the success rate of over 99%. 5. Support Wentai, Beihang Haier, ARTCAM, Type3 and other software to generate standard G code path to the file. The control system uses U-exchange processing document, easy to operate desktop CNC plasma cutting machine is a high-speed, precision, miniaturization of the cutting device. Man-machine interface, easy to install, simple to operate. The machine uses plasma cutting mode, particularly suitable for medium and book nonferrous metal plates, stainless steel and carbon steel plate automated cutting stock. Plasma cutting machine has the advantage of plasma arc energy is more concentrated, the higher the temperature, the cutting speed, small deformation, but also cut stainless steel, aluminum and other materials. Plasma cutting machine with different working gas can cut a variety of metal cutting oxygen cutting difficult, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel) cut better; CNC cutting machine CNC cutting machine maintenance Shihezi _ _ Yu Hing Co., NC-NC provided by Zhengzhou jade products.
