In today's society, with the progress and development of science and technology, the machining industry has ushered in tremendous changes. From the initial development of simple oxygen cutting to intelligent CNC plasma cutting, and then high-tech high-performance laser cutting of the popularity of civilians, prompting the rapid development of the machining industry. However, in the choice of cutting machine, CNC plasma cutting machine and laser cutting machine and what are the differences?

CNC plasma cutting machine is a new type of thermal cutting equipment, its working principle is the use of high temperature plasma arc heat to make the metal at the workpiece kerf local melting, and high-speed plasma momentum to exclude the molten metal to form the kerf of a processing method. Plasma cutting development to the present, the working gas can be used on the plasma arc cutting characteristics, as well as cutting quality and speed have a significant impact. Commonly used plasma arc working gas argon, hydrogen, nitrogen, oxygen, air, water vapour and some gas mixtures. Plasma cutting machine is widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general-purpose machinery, engineering machinery, steel structure and other industries! Laser cutting is the use of high power density laser beam scanning over the surface of the material, in a very short period of time will be heated to thousands to tens of thousands of degrees Celsius, so that the material melting or gasification, and then high-pressure gas will be melted or gasification of the material from the slit blowing away, to achieve the purpose of cutting the material. Laser cutting, due to the invisible beam instead of the traditional mechanical knife, the mechanical part of the laser cutter head and the work without contact, in the work will not cause scratches on the work surface; laser cutting speed, the kerf is smooth and flat, generally without subsequent processing; cutting heat-affected zone is small, the plate deformation is small, the kerf is narrow (0.1mm~0.3mm); the kerf has no mechanical stress, no shear burr; processing High precision, good repeatability, no damage to the surface of the material; CNC programming, can be processed any planar graph, can be a large width of the whole plate cutting, no need to open the mould, economic and time-saving. In terms of cutting accuracy, plasma can reach within 1mm, the laser can reach within 0.2mm; in the cost of plasma cutting machine relative to laser cutting machine is much cheaper, in the processing accuracy of plasma cutting relative to laser cutting is a rough processing, a fine processing!
