A laser cutting machine is a laser beam emitted from a laser that is focused by a light path system into a laser beam of high power density. The laser beam is irradiated onto the surface of the workpiece to bring the workpiece to a melting point or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.
As the beam moves relative to the workpiece, the material is finally slit, thereby achieving the purpose of cutting.
Laser cutting processing replaces traditional mechanical knives with invisible beams. It has high precision, fast cutting, is not limited to cutting pattern limitation, saves materials by automatic typesetting, smooth cuts, low processing cost, etc., and will gradually improve or replace Traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the workpiece, and it will not scratch the surface of the workpiece during operation; the laser cutting speed is fast, the slit is smooth and flat, and generally no subsequent processing is required; the cutting heat affected zone is small, the sheet deformation is small, and the slit is narrow ( 0.1mm~0.3mm); no mechanical stress in the incision, no shear burr; high processing precision, good repeatability, no damage to the surface of the material; NC programming, can process any plan, can cut the whole board with large format, no need Open the mold, saving time and economy.
Laser processing technology has a very important position in sheet metal processing technology, which improves the labor productivity of sheet metal processing and promotes the development of sheet metal processing. The high degree of flexibility of the laser cutting machine can greatly reduce the processing cycle, the cutting speed is fast, the production efficiency is high, the processing precision is improved, and the development speed of the product is accelerated. These advantages are concerned by many manufacturing companies.
Competitive advantages:
The laser cutting machine is a technological revolution of sheet metal processing, and is the “processing center” in sheet metal processing. The laser cutting machine has high flexibility, high cutting speed, high production efficiency, short product production cycle, and has won extensive customers. In the market, the effective life of the technology is long. Most foreign steel plates with a thickness of more than 2 mm use laser cutting machines. Many foreign experts agree that the next 30-40 years is the golden age of laser processing technology development.
Generally speaking, it is recommended to use a laser cutting machine for cutting metal materials such as carbon steel sheets within 12 mm or stainless steel sheets within 10 mm. The laser cutting machine has no cutting force and no distortion in processing: no tool wear and good material adaptability: whether it is simple or complicated parts, laser can be used for precision precision rapid cutting: its slit is narrow, cutting quality is good, and automation is high. Simple operation, low labor intensity, no pollution: automatic cutting and nesting of cutting can be realized, material utilization rate is improved, production cost is low, and economic benefits are good.
There are many factors to consider when purchasing a laser cutting machine. In addition to considering the maximum size, material, maximum thickness of the workpiece to be cut, and the size of the raw material, more needs to be considered in the future. The maximum workpiece size to be processed after the technical modification, the material of the material provided by the steel market, which is the most material for the product, the loading and unloading time, and so on.
