In the machining process, commonly used methods are manual sheet cutting cutting, semi-automatic cutting machine and CNC cutting machine. Hand cutting flexibility, but poor quality hand-cut, size error, waste material large, the subsequent processing workload, while poor working conditions, low productivity. Semi-automatic cutting machine profile cutting machine, cutting good quality piece of plasma cutting machine, because of its use of cutting dies, is not suitable for single-piece, small and large workpiece cutting. Although other types of semi-automatic cutting machine reduces the labor intensity cutting machine price, but its function is simple, only for some of the more regular shape parts cut. CNC cutting relative manual and semi-automatic cutting mode, it can effectively improve the sheet metal cutting efficiently, cutting quality, which can reduce the labor intensity of land. In some of our small and medium enterprises and even the use of hand-cut and semi-automatic cutting mode it is also more common in large enterprises. China's machinery industry of steel use has reached 300 million tons, cut the amount of steel is very large; cutting machine parameters with the development of modern machinery industry, sheet metal cutting requirements for work efficiency and product quality also improved. So the market potential is still very large CNC cutting machine, the market outlook is more optimistic. Cutting operation and with personal protection: 1 site using plasma cutting machine machine, shall be provided with rain, moisture, sun hangar, and shall be equipped with appropriate fire-fighting equipment. 2. When the cutting height, must wear seatbelts, cut and then cut around the bottom of the fire prevention measures should be taken, and should someone care. 3. When the required cutting pressure vessels, sealed containers, drums, pipes, stained with the workpiece when the combustible gas and the solution should be to eliminate the pressure vessel and piping to eliminate flammable gases and solution, then rinse toxic, hazardous, flammable substance; for there are remnants of oil containers, you should use steam, alkaline washing, and open the flap, make sure the container clean, then filled with water before cutting. Welding in containers should be taken to electrocution, poisoning, and measures to prevent suffocation. Cut vents should remain sealed container cutter, if necessary, into the air outlet of the installed equipment ventilation; lighting voltage inside the container shall not exceed 12V, between the welder and the work should be insulated; outer container should set up special monitoring. Already prohibited in the sprayed paint and plastic container cutting. 4. Status of pressure vessels and pressure pipes, charging device, carrying parts of the force structure and containing flammable, non-explosive materials container cutting. 5. The rain can not be in the open air welding. When working in wet areas, the operator should stand covered with insulating materials place and should wear insulated shoes. 6. After the operation, it should cut off the power, turn off the gas supply and water.
