Laser cutting technology is a comprehensive high-tech technology. It spans the disciplines of optics, material science and engineering, mechanical manufacturing, numerical control technology and electronics. It belongs to the hot spot of science and technology and industry at home and abroad.  Over the past 50 years, laser processing technology and applications have developed rapidly. It combines with many disciplines to form a number of technical applications. The main processing technologies of laser include: laser cutting, laser welding, laser marking, laser drilling, laser heat treatment, laser rapid prototyping, laser coating and so on.

Advantages of laser cutting technology in industrial applications

 Laser cutting technology is the main application of laser technology in the industry. It accelerates the transformation of the traditional processing industry and provides new means for modern industrial processing. It has become the most widely used laser processing method in industrial processing. At present, laser cutting technology has been widely used in machinery manufacturing, bridge construction, sheet metal processing, ship and automobile manufacturing, electrical and electronic, aerospace and other pillar industries of the national economy. With the continuous progress and application of science and technology, laser cutting technology is bound to further develop into other fields.

 In the past few years, the development of laser processing technology is very rapid, and its application is increasingly widespread. As a result, lasers have been called "universal processing tools" and "universal processing methods for future manufacturing systems". Businesses in developed industrialized countries are undergoing a qualitative change due to the widespread use of laser processing technology. Laser cutting technology is the main application of laser technology in the industry. It accelerates the transformation of traditional processing industries and provides new means for modern industrial processing. It has become the most widely used laser processing method in the field of industrial processing and can solve the problems of the entire laser processing industry. More than 70%.

Laser cutting effectively uses a focused, high power density laser beam to irradiate the workpiece. At laser power densities above the laser threshold, the energy of the laser beam and the heat of the chemical reaction added by the active gas-assisted cutting process are all absorbed by the material, which results in the temperature reaching The effect of the laser is a sharp rise. After reaching the boiling point, the material begins to evaporate and a hole is formed. As the beam moves relative to the workpiece, the material is eventually cut through and the deposit at the slit is blown away by some sort of auxiliary gas.

 Laser cutting is characterized by wide cutting range, fast cutting speed, narrow kerf, good cutting quality, small heat-affected zone and great flexibility. It has been widely used in modern industry. Laser cutting technology has also become laser processing technology. One of the most mature technologies. Compared with other light, laser has the following characteristics: high brightness, high directionality, high monochromaticity and high coherence. It is due to the four main characteristics of laser light that it is widely used, giving laser processing the following valuable features not found in conventional processing:

(1) Various machining treatments are possible because there is no contact processing and the energy and speed of movement of the laser beam are adjustable.

 (2) It can be used to process a variety of metals and non-metals, especially materials with high hardness, brittleness and melting point.

 (3) There is no "tool" wear and no "cutting force" on the workpiece during laser processing.

 (4) Laser processing workpiece heat-affected zone is small, the workpiece thermal deformation is small, less follow-up processing.

 (5) The laser can be transparent medium through the workpiece in the closed container for a variety of processing.

 (6) The laser is easy to guide. By focusing, conversion in all directions can be realized, and it is easy to cooperate with the numerical control system to deal with complex workpieces. Therefore, laser cutting is a very flexible cutting method.

 (7) Laser processing has high productivity, stable and reliable processing quality, and significant economic and social benefits.
