Plasma cutting is a high-temperature, high-speed plasma arc cutting machine, CNC laser to heat the molten metal to be cut, and high-speed air to blow away the molten metal. It all kinds of metal materials (stainless steel, carbon steel, copper alloy, aluminum, copper, nickel, titanium, etc.) were cut with a cutting speed, cut narrow, small deformation, saving materials and so on. Power cut in two parts of the main circuit and control circuit, electrical principles: high leakage reactance of the main circuit three-phase power transformers, three-phase bridge rectifier, high-frequency components such as ignition coil and protection, including contactors, air plasma composed works 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: In the post-connect the power and gas supply CNC cutting machine software, close 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, gas is turned on, the torch pre-ventilation. 1. The structure of the machine frame is welded structure, firm and reasonable CNC cutting machine, simple, durable. 2. Cutting speed, high precision. Cutting mouth small CNC cutting machine maintenance, 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. Automatic arc, 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 CNC cutting machine wages, Zhuji CNC cutting machine, CNC Ltd Yu Xing Yu provided by the Zhengzhou-NC products.
