A laser cutting machine focuses the laser emitted from the laser into a high-power laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing it to reach the melting or boiling point, while the high-pressure gas coaxial with the beam blows away the melted or vaporized metal.
As the beam of light moves relative to the workpiece, the material eventually forms a cutting seam, thereby achieving the purpose of cutting.
Laser cutting processing replaces traditional mechanical knives with invisible beams of light. It has the characteristics of high accuracy, fast cutting, not limited to cutting pattern limitations, automatic layout saving materials, smooth cuts, and low processing costs. It will gradually improve or replace traditional metal cutting process equipment. The mechanical part of the laser blade does not come into contact with the workpiece, and will not cause scratches on the surface of the workpiece during operation; Laser cutting speed is fast, and the incision is smooth and flat, generally without the need for subsequent processing; The cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow (0.1mm~0.3mm); The incision is free of mechanical stress and shear burrs; High machining accuracy, good repeatability, and no damage to the material surface; CNC programming, capable of processing any flat plan, capable of cutting large entire boards without the need for mold opening, economical and time-saving.
Laser processing technology plays a very important role in sheet metal processing technology, improving labor productivity and promoting the development of sheet metal technology. The laser cutting machine is highly flexible, which can greatly reduce the Makespan, has fast cutting speed, high production efficiency, improves processing accuracy, and speeds up product development. These advantages have been concerned by many manufacturing enterprises.
Competitive advantage:
Laser cutting machine is a technological revolution in sheet metal processing, serving as the "processing center" in sheet metal processing; Laser cutting machines have a high degree of flexibility, fast cutting speed, high production efficiency, and short product production cycles, which have won a wide market for customers. The effective life of this technology is long, and laser cutting machines are mostly used for plates with a thickness exceeding 2mm in foreign countries. Many foreign experts always believe that the next 30-40 years will be a golden period for the development of laser processing technology.
Generally speaking, it is recommended to use laser cutting machines for cutting metal materials such as carbon steel plates within 12mm and stainless steel plates within 10mm. The laser cutting machine has no cutting force, no deformation in processing, no tool wear, and good material adaptability: both simple and complex parts can be cut by laser precision Rapid prototyping in one time: its cutting seam is narrow, cutting quality is good, automation is high, operation is simple, labor intensity is low, and no pollution: it can achieve automatic cutting layout, nesting, improve material utilization, low production cost, and good economic benefits.
There are many factors to consider when choosing a laser cutting machine. In addition to considering the current maximum size, material, maximum thickness to be cut, and size of raw material format, more attention needs to be paid to future development directions, such as the maximum workpiece size to be processed after the technical modification of the product, the material format provided by the steel market, which type of material is most cost-effective for one's own product, and the loading and unloading time.
