A Brief Introduction of Plasma Cutting Machine
Plasma cutting machine is a kind of metal cutting equipment with different working gases. It can cut metal plates and tubes of different thicknesses. It is an efficient metal braking power tool.
A plasma cutting machine is a machine that uses plasma cutting technology to process metal materials. By using different working gases, you can cut all metals that are difficult to cut with oxygen, especially non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel). Another way of plasma cutter is flame cutting machine, the two cutting methods are different.
Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to partially or partially melt (and evaporate) the metal in the cut of the part, and use high-speed plasma pulses to process it. Remove molten metal. Plasma cutting with different working gases can cut metals that are difficult to cut with oxygen, especially some non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel). Choosing the right gas for cutting will greatly affect the cutting effect. Especially when cutting ordinary carbon steel plates, the speed can reach 5-6 times that of the oxygen cutting method, the surface cutting edge is smooth, the thermal deformation is small, and the heated area is small.
Plasma cutting machines are now widely used in automobile and machinery industries; construction, furniture, decoration, shipbuilding and other industries. Now a plasma cutting machine has been developed to process the available working gas (the working gas is the conductive medium of the plasma arc, it is also the coolant, and the molten metal in the incision must be removed at the same time). Cutting characteristics, cutting quality and plasma arc speed all have a significant influence. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and certain gas mixtures.
In recent years, new technologies such as fine plasma or high-precision plasma have been widely used and achieved good results. By improving the design of the cutting torque, the quality of the cutting surface of the workpiece can be greatly improved. The verticality of the shaft edge can reach 0-1.5°, which is particularly useful for improving the cutting quality of thick plates. Thanks to the improved cutting gun, the service life of the electrode has been increased several times. However, the distance between the torch and the steel plate is relatively large, and the torch height sensor needs to be more sensitive and the torch response speed is faster. Therefore, CNC plasma machine is particularly suitable for cutting 4-30mm steel plates, which can effectively avoid the defects of low oxygen and lack of oxygen, large deformation, serious cutting and serious slag problems. In some small and medium-sized enterprises and even large enterprises, manual cutting and semi-automatic cutting are more common. The amount of steel cut in the machinery industry is very large. With the development of modern machinery industry, the requirements for work efficiency and the quality of sheet metal cutting products are getting higher and higher. Therefore, the market potential of CNC plasma cutting machine is still great, and the market prospect is relatively optimistic.
