The laser cutting machine is to focus the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.
As the relative position of the beam and the workpiece moves, the material will finally form a slit, so as to achieve the purpose of cutting.
Laser cutting processing is to replace the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting pattern restrictions, automatic typesetting, saving materials, smooth cuts, and low processing costs. Will gradually improve or replace the traditional metal cutting process 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 work; the laser cutting speed is fast, the incision is smooth and flat, and generally does not require subsequent processing; the cutting heat affected zone is small, the plate deformation is small, and the slit is narrow ( 0.1mm~0.3mm); the incision has no mechanical stress, no shearing burr; high processing accuracy, good repeatability, and no damage to the surface of the material; CNC programming, can process any plan, and can cut large-format whole plates without Opening the mold saves time and economy.
Laser processing technology has a very important position in the sheet metal processing technology, which improves the labor productivity of the sheet metal process and promotes the development of the sheet metal process. 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 accuracy is improved, and the product development speed is accelerated. These advantages are paid attention to by many manufacturing companies.
Laser cutting machine is a technological revolution in sheet metal processing, and it is the 'processing center' in sheet metal processing; laser cutting machine has a high degree of flexibility, fast cutting speed, high production efficiency, and short product production cycle. It has won a wide range of markets for customers and the technology has a long effective life. Most foreign plates with a thickness of more than 2 mm use laser cutting machines. Many foreign experts agree that the next 30-40 years will be the golden period for the development of laser processing technology.
Generally speaking, it is recommended to use a laser cutting machine to cut 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, good material adaptability: no matter it is simple or complex parts, it can be cut with laser precision and rapid prototyping at one time: its slit is narrow, the cutting quality is good, and the degree of automation is high. Easy to operate, low labor intensity, no pollution: automatic cutting and nesting can be realized, the material utilization rate is improved, the production cost is low, and the economic benefit is good.
There are many factors to consider when choosing a laser cutting machine. In addition to the maximum size of the workpiece, the material, the maximum thickness that needs to be cut, and the size of the raw material width, more considerations need to be given to the future development direction. , Such as the size of the largest workpiece to be processed after the technical modification of the product, the breadth of the material provided by the steel market, which is the most economical for your product, and the loading and unloading time.
