Application advantages of laser cutting technology

Laser cutting technology is a comprehensive high-tech technology, which mixed the optical, materials science and engineering, machinery manufacturing, numerical control technology and electronic technology and other disciplines, currently, it is the hot spot common concern of science & technology field and industrial circles, both at home and abroad. For more than 50 years, laser processing and application developing rapidly, has combined with many disciplines form into a number of application filed, and laser main processing technologies include: laser cutting, laser welding, laser marking, laser drilling, Laser heat treatment, laser rapid prototyping, laser coating and so on.

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

Application advantages of laser cutting technology

In recent years, laser processing technology is developing very rapidly. Its application is becoming more and more widely. so the laser is known as "universal processing tool" and "future manufacturing system common processing means". Advanced industrial countries’ production technology is making a qualitative change because of the extensive application of laser processing technology. Laser cutting technology is the main application of laser technology in industry. It has accelerated the transformation of traditional processing industry and provided new means of modern industrial processing. It has become the most widely used laser processing method in industrial processing field, which can occupy the whole laser processing industry more than 70%.

Laser cutting is the use of focused high power density laser beam irradiating the workpiece. Under the premise of exceeding laser threshold of laser power density, laser beam energy and active gas assisting cutting process attached chemical reaction heat are all absorbed by the material. The temperature of the laser action point rises sharply and after boiling point reached, material begins to vaporize and forms the hole. With the relative movement of light beam and workpiece, the material is finally formed into a slit. The sediment at the slit is blown by a certain auxiliary gas.

Laser cutting has several advantages such as wide range of cutting, cutting speed, slit narrow, good cutting quality, small heat affected area, plus flexible and etc. These advantages have been a very wide range of applications in modern industry. Laser cutting technology has also become one of the most mature technologies in laser processing technology. Compared with other lights, here are some features as follows:
1. High brightness
2. High directionality
3. High monochrome
4. High coherence

Also due to these four features, it has been widely used, and has brought valuable features for the following traditional processing to the laser processing:
(1) Since there is no contact processing, and the laser beam energy and movement speed are adjustable. So you can achieve a variety of processing.
(2) It can be used to process a variety of metal, non-metallic. In particular, it can be processed high hardness, high brittleness and high melting point of the material.
(3) There is no "tool" wear during laser processing, and no "cutting force" acting on the workpiece.
(4) Laser processing of the workpiece heat affected area is small, small deformation of the workpiece, follow-up small amount of processing.
(5)The laser can process the workpiece in the closed container through the transparent medium.
(6)The laser is easy to guide. it can be achieved in the direction of transformation through the focus. It is very easy to cooperate with the CNC system for processing complex parts. Therefore, laser cutting is a very flexible cutting method.
(7) Laser processing has high production efficiency. Processing quality is stable and reliable, significant economic and social benefits.
