A laser cutting machine emits a laser beam from a laser, which is focused into a high power density laser beam through an optical circuit system. The laser beam is directed onto the surface of the workpiece to bring the workpiece to its melting or boiling point, while a high-pressure gas coaxial to the beam blows away the melted or evaporated metal.
As the beam moves relative to the workpiece, the material is eventually sliced through, allowing for cutting.
Laser cutting process replaces the traditional mechanical tool with an invisible beam. It has the advantages of high precision, fast cutting speed, no limitation of cutting pattern, automatic discharging to save material, smooth cutting, low processing cost, etc., and will gradually improve or replace the traditional metal cutting processing equipment. The mechanical part of the laser cutter head has no contact with the workpiece, and will not scratch the surface of the workpiece during operation; fast laser cutting speed, smooth and flat cutting, generally no need for subsequent processing; small cutting heat-affected zone, small sheet deformation, and narrow kerf (0.1mm~0.3mm); no mechanical stress on the kerf, and no shear burrs; high processing accuracy, good repeatability, and no damage to the surface of the material; numerical control programming, which can deal with any plan , can cut the whole plate substantially without opening the mold, saving time and economy.
Laser processing technology occupies a very important position in sheet metal processing technology, improving the labor productivity of sheet metal processing and promoting the development of sheet metal processing. The high flexibility of laser cutting machine can greatly shorten the processing cycle, fast cutting speed, high productivity, improved processing accuracy and faster product development. Many manufacturing companies focus on these advantages.
Competitive advantages:
The laser cutting machine is a technological revolution in sheet metal processing, and is the "processing center" of sheet metal processing. The laser cutting machine has high flexibility, fast cutting speed, high productivity, short production cycle, won the favor of customers. In the market, the effective life of the technology is very long. Most of the foreign steel plates with a thickness of more than 2 millimeters use laser cutting machines. Many foreign experts believe that the next 30 - 40 years is the golden age of laser processing technology development.
In general, it is recommended to use laser cutting machines to cut metal materials, such as carbon steel plates within 12 mm or stainless steel plates within 10 mm. Laser cutting machine without cutting force, processing without deformation: no tool wear, good material adaptability: whether simple or complex parts, the laser can be used for precision fast cutting: narrow kerf, good cutting quality, and a high degree of automation. Simple operation, low labor intensity, no pollution: can realize cutting automatic cutting and nesting, improve material utilization, low production costs, good economic efficiency.
There are many factors to consider when buying a laser cutting machine. In addition to considering the maximum size, material, the maximum thickness of the workpiece to be cut and the size of the raw material, the future needs to be considered more. The maximum size of the workpiece to be processed after technological modifications, the material available in the steel market, which is the most important material for the product, loading and unloading time, etc..
