Various types of CNC cutting machine features and applications of CNC flame cutting machines, cutting having a large thickness steel cutting ability, low cutting costs, but there are cutting deformation, cutting accuracy is not high, and low cutting speeds, cutting preheat time, piercing a long time, difficult to adapt to a fully automated operation. Its application is mainly limited to steel, thick sheet metal cutting, in the thin steel plate cutting on plasma cutting will be gradually replaced. CNC plasma cutting machine, plasma cutting with a cutting width of the field, you can cut all the sheet metal, cutting speed, high efficiency, cutting speeds up to 10m / min or more. Pollution when plasma cutting underwater cutting can eliminate generation of noise, dust, harmful gases and arc, and effectively improve the workplace environment. The precise plasma cutting has made cutting the level of quality close to laser cutting, along with high-power plasma cutting technology matures cutting machine maintenance, cutting thickness more than 100mm, widening the CNC plasma cutting machine range. Practice: 1. When cutting before use and check that the power supply, gas supply, no water leakage, leakage, leakage, safe and reliable ground or zero. 2. The car, the workpiece should be placed in the proper position, and the workpiece and the cutting circuit should be turned positive, cut below the working surface to be provided with slag pit. 3. It should be based on the workpiece material, type and thickness selected nozzle diameter cutter model, adjustment of the cutting power, within the gas flow and the electrode shrinkage. 4. Automatic cutting car should be running through empty, and the cutting speed is selected. 5. The operator must wear protective masks, welding gloves, hats, dust masks and filters soundproof earmuffs. Who do not wear goggles plasma arc prohibited direct observation, bare skin is prohibited near the plasma arc. 6. When cutting, the operator should stand upwind operation. Ventilation from the lower part of the table, and should reduce the operating table of open area. 7. When cutting, when the no-load voltage is too high cutting machine, you should check the electrical grounding, then zero and torch handle insulation should workbench and floor insulation cutter parameters, or install a no-load open circuit in the electrical control system breaker. 8. The high-frequency generator should be provided with a shield cover, with high-frequency arc, it should immediately cut off high-frequency circuits. 9. Using thorium, tungsten electrode should comply with Article 12.7.8 stipulates JGJ33-2001.
