Plasma Cutting Machine Details

A plasma cutter is a power tool for processing metal materials using plasma cutting technology. Using different working gases, it can cut a variety of metals that are difficult to cut with oxygen, especially non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel). The opposite of the plasma cutting machine is the 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 locally melt (and evaporate) the metal at the workpiece kerf, and uses the momentum of a high-speed plasma to remove the molten metal to form the kerf. The plasma cutting with different working gases can cut all kinds of metals that are difficult to cut with oxygen, especially non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel). The cutting effect is better; its main advantage is that the thickness of the metal is not large. At this time, the plasma cutting speed, especially when cutting ordinary carbon steel plate, the speed can be up to 5-6 times the oxygen cutting method, smooth cutting surface, thermal deformation is small, less heat-affected zone.

Plasma cutting machine is widely used in automobile, locomotive, pressure vessel, chemical machinery, nuclear industry, general machinery, construction machinery, steel structure, ship and other industries.

Plasma cutting machine adopts different working gases, can cut all kinds of metals which are difficult to cut by oxygen, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel); its main advantage is to cut metals with small thickness When cutting, plasma cutting speed is fast, especially when cutting thin plates of ordinary carbon steel, the speed can be up to 5-6 times that of the oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, almost no heat-affected zone. There is no heat-affected zone.

Plasma cutting machine development to the present, the available working gas (working gas is the plasma arc conductive medium, but also the heat carrier, at the same time must remove the molten metal in the kerf). The cutting characteristics of the plasma arc, cutting quality and speed have a significant impact. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some gas mixtures.

In recent years, the new technology of fine plasma or high-precision plasma has been widely used and achieved good results. By improving the design of cutting torque, the quality of the cutting surface of the workpiece is obviously improved. The perpendicularity of the axis edge can reach 0-1.5°, which is especially conducive to improving the cutting quality of thick plates. Due to the improved cutting torch, the electrode life has been extended several times. However, the relatively high distance between the torch and the steel plate requires a more sensitive h8 sensor on the torch and a faster torch response. Therefore, plasma cutting of 4-30 mm steel plates is an ideal method that avoids the disadvantages of hypoxia and oxygen deficiency, high distortion, severe cutting and severe slag entrapment.

Manual and semi-automatic cutting is more common in some small and medium-sized enterprises, and even in some large ones. The volume of steel cutting in the machinery industry is very large. With the development of modern machinery industry, the working efficiency of sheet metal cutting and product quality requirements are getting higher and higher. Therefore, the market potential of CNC plasma cutting machine is still very large, and the market outlook is relatively optimistic.
