Numerical control plasma cutting machine is a new type of hot cutting equipment, its working principle is to use the heat of high temperature plasma arc to make the metal in the workpiece incision local melting, and by the momentum of high speed plasma to eliminate the molten metal to form a notch processing method.

1. With the development of plasma cutting to the present, the available working gas has a significant impact on the cutting characteristics, cutting quality and cutting speed of the plasma arc. Common plasma arc gases include argon, hydrogen, nitrogen, oxygen, air, water vapor, and some mixed gases.

Plasma cutting machine widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structure and other industries!

2, laser cutting is the use of high power density laser beam scan over the surface of the material, in a very short time to heat the material to thousands to tens of thousands of degrees Celsius, melting or gasification of the material, and then use high pressure gas to melt or gasify the material from the slit blown away, to achieve the purpose of cutting the material. Laser cutting, because the invisible beam of light is used to replace the traditional mechanical knife, the mechanical part of the laser cutting head has no contact with the work, in the work will not cause scratches on the work surface; Laser cutting speed is fast, the incision is smooth and flat, generally without subsequent processing; Small heat-affected area, small plate deformation, narrow slit (0.1mm~0.3mm); The incision has no mechanical stress and no shear burr. High precision, good repeatability, no damage to the material surface; Numerical control programming, can process arbitrary plane, can cut the whole board with a large width, no need to open a mold, economy and time.

General: in terms of cutting precision, plasma can reach within 1mm, laser can reach within 0.2mm; On the cost of plasma cutting machine relative to the laser cutting machine is much cheaper, in the processing precision plasma cutting relative to the laser cutting is a rough machining, a fine machining!
