The laser was a new light source in the 1960s. Laser is widely used because of its good directional, high brightness. Laser processing is one of the most promising fields of laser application, now has developed more than 20 kinds of laser processing technology, such as common laser cutting, laser welding, laser engraving, laser drilling, laser etching, laser surgery, laser weapons, laser energy and so on. In this video we’re going to focus on laser cutting. Laser cutting is one of the most important application in the laser processing industry technology, is a kind of non-contact processing, based on the hot manufacturing process, combined with focus on the heat and heat, pressure on the narrow path or slit material melting and injection, and the relative movement between laser beam and materials along a certain path, thus forming a certain shape of cutting seam, It is widely used in the processing of metal and non-metallic materials, in which the pulse laser is suitable for metal materials, and the continuous laser is suitable for non-metallic materials. The use of laser cutting can greatly reduce the processing time, reduce the processing cost, improve the quality of the work piece. The modern laser has become the “sword” that people dream of pursuing. Laser cutting is currently the world’s advanced cutting technology, compared with the traditional cutting, laser cutting has precision manufacturing, flexible cutting, special-shaped processing, a forming, fast speed, high efficiency advantages, so in industrial production to solve many conventional methods can not solve the problem. The highly focused energy provided by the laser and the control of the computer numerical control machining center can accurately cut materials from a variety of different thicknesses and complex shapes. Laser cutting can achieve high precision and small tolerance manufacturing, reduce material waste, processing material diversity, below we detail the manufacturing industry why the use of precision laser cutting several reasons:
Excellent machining accuracy and product quality
Compared with the traditional cutting method, laser cutting products have higher precision and edge quality, it is because laser cutting belongs to the “cold processing”, the use of highly focused beam, in the cutting process as a heat affected zone, will not cause large area of thermal damage to the adjacent surface. In addition, a high-pressure gas cutting process (usually CO2) is used to spray molten material to remove material cuts for narrower work pieces, allowing cleaner processing and smoother edges for complex shapes and designs. Laser cutting machine with computer numerical control function, laser cutting process can be automatically controlled by a pre-designed machine program. The risk of operator error is greatly reduced, and the components and other products are produced more accurately, more accurately, and with stricter tolerances.
Improve workplace and operator safety
Traditional cutting processing is an area where factory accidents occur frequently. Once a workplace safety accident occurs, it will have a very large negative impact on the company’s productivity and operating costs. The use of laser cutting can effectively reduce the risk of safety accidents, because it is a non-contact process, meaning that the machine does not physically contact the material. In addition, there is no need for any operator intervention during the laser cutting process, so that the high-power beam is safely kept inside the sealed machine. Typically, laser cutting requires no human intervention except for inspection and maintenance operations, and the process minimizes direct contact with the work piece surface compared to traditional cutting methods, thereby reducing the potential for employee accidents and injuries.
In line with a variety of materials and thickness processing
In addition to allowing complex geometry to be cut with greater precision, laser cutting also allows manufacturers to cut without mechanical modification, for a wider variety of materials and a wider range of thicknesses. Use the same beam with different output levels, and intensities. Laser cutting can cut all kinds of metal and nonmetal materials, the machine can do similar adjustment precision cutting of various thickness of material, through the integration of numerical control system can realize automation, so as to provide more intuitive, pengwo laser developed more specialized in high efficiency laser processing equipment and the overall solution.
