CNC plasma cutting machine has been widely used in various industries such as machinery, shipbuilding, steel structure, automobile, easy pressure, etc., and is gradually replacing the leading position of flame cutting in a certain field. Plasma cutting machine is a kind of high-precision mechanical instrument and the requirements of cutting product precision. There are many precautions for the operation of the plasma cutting machine , which needs the attention of operators.
1, plasma cutting processing range
Plasma cutting is ideal for cutting steel and non-ferrous metals with a thickness of less than 1 inch. Flame gas cutting requires the operator to carefully control the cutting speed to maintain the oxidation treatment. Plasma cutting is more flexible in this regard. Some applications of plasma cutting are excellent in some aspects. For example, cutting metal sheets, which is unattainable when cutting with flame gas. In addition, compared with mechanical cutting methods, plasma cutting speed is much faster, and non-linear cutting is easier. In cutting metal materials such as aluminum, copper, and stainless steel, it is the strong point of plasma cutting machine!
Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to locally melt (and evaporate) the metal at the cut of the workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form the cut.
3. Comparison of plasma cutting and flame gas cutting
Plasma cutting works only on metals that can be used as conductors—mild-carbon steel, aluminum, and stainless steel are typical examples. When cutting mild steel, operators will experience high-speed, deeper cutting effects. Flame gas cutting cuts by burning high temperatures, or cutting metal by oxidation. Therefore, the scope of its application is limited to the ferrous metals that can be treated with oxidation technology just now. Metals like aluminum and stainless steel will form oxides that constrain further oxidation. This makes it impossible for conventional flame gas cutting to handle this type of material. Plasma cutting, which does not rely on oxidation treatment, can effectively cut aluminum, steel and other conductive metals. Moreover, different types of gases can be used in plasma cutting. At present, most people use compressed air for plasma cutting. Air compressors are available in most cities. Therefore, plasma cutting does not require gases such as flammable gases and compressed oxygen as operating gases. When cutting thick plates, plasma cutting is more expensive than flame gas cutting. Flame gas cutting does not require a power supply and compressed air, which is easier for some users. Flame gas cutting is faster than plasma cutting when the steel is thicker, but the plasma cutting machine is faster than flame cutting when cutting thin plates, and it is more efficient and better!
