With the development of modern machinery industry, cutting quality, continuous improvement of accuracy, to improve production efficiency, reduce production costs, with automatic cutting function of high intelligence is rising. Development of CNC cutting machine must adapt to the requirements of modern machinery industry development. 1, CNC cutting machine development. CNC cutting machine from several common application point of view, CNC flame cutting machines function and performance have been more perfect, the limitations of the material cut (only cutting carbon steel plate) cutting machine, cutting slow, low productivity and cutting machine parameters , gradually narrowing its scope cutter, the market can be a big increase. Plasma cutting machine with improved cutting a wide range (cutting all metallic materials), cutting speed, work efficiency, the future direction that the plasma power technology, numerical control systems and plasma cutting with the problem, such as electrical power upgrade can be cut More thick plate; fine plasma technology to improve and enhance the cutting speed can be increased, cut quality and cutting accuracy; improve and enhance the CNC system to accommodate plasma cutting, which can effectively improve work efficiency and cutting quality. Cutting Process: Pre-ventilation - the main circuit power supply - frequency arc - cutting - interest arc - stop. Powered by the main circuit contactor control; through short gas controlled by a solenoid valve; a high-frequency oscillator by the control circuit controls the ignition arc, and after the establishment of the high-frequency arc stop working. Furthermore, the control circuit still has the following internal lock function: thermal switch is activated to stop working.
