Working principle of fiber laser cutting machine

Fiber laser cutting machine is a newly developed processing equipment after CO2 and YAG. Compared with the previous one, it has a disruptive change. This is not only reflected in the technological innovation, but also a breakthrough in processing efficiency and processing intelligence. The principle of the fiber laser cutting machine is to use a fiber laser to emit a beam of light to focus it on the processed workpiece with a high density through a reflection and focusing lens, and then melt the metal at high temperature, and blow the melt away by the auxiliary gas to achieve the purpose of cutting.

　　Laser cutting processing is to replace the traditional mechanical knife with an invisible beam. It has high precision, fast cutting, not limited to cutting patterns, automatic typesetting, saving materials, smooth cuts, and low processing costs. It 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 it 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 the entire board with a large format without Opening the mold saves time and economy.

　　Compared with CO2 and YAG cutting machines, fiber laser cutting machines have greatly improved accuracy and speed. The cutting seam is small and is not restricted by the shape. It belongs to a non-contact cutting method, and the cutting end surface is smooth without burrs. There is no deformation.

　　 With technological innovations in recent years, fiber laser cutting machines have made great progress in the field of high power, and have made major breakthroughs in the cutting of thick metal plates.

need huge investment, so it is important to shop with caution.
