Optical fiber laser cutting machine is a newly developed processing equipment after CO2 and YAG. It has a disruptive change compared with the former. This is not only reflected in the technical innovation, but also a breakthrough in processing efficiency and processing intelligence. The principle of the fiber laser cutting machine is that the fiber laser emits a light beam to focus its high-density focus on the processed workpiece through the reflection and focusing lens, and then melts the metal at high temperature, and blows the molten material through the auxiliary gas to achieve the purpose of cutting.
The laser cutting process replaces the traditional mechanical knife with an invisible light beam. It has the characteristics of high precision, fast cutting, not limited to cutting pattern restrictions, automatic layout to save materials, smooth incisions, and low processing costs. It will be gradually improved or replaced by Traditional metal cutting process equipment. The mechanical part of the laser cutter head is not in contact with the workpiece, and will not cause scratches on the surface of the workpiece during the work; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat affected zone is small, the plate deformation is small, and the cutting slit is narrow 0.1mm ~ 0.3mm); the incision has no mechanical stress and no shear burrs; the processing accuracy is high, the repeatability is good, and the surface of the material is not damaged; the CNC programming can process any plan, and can cut the whole board with a large breadth, without Open the mold, economy and time-saving.
Compared with the CO2 and YAG cutting machines, the fiber laser cutting machine has greatly improved the accuracy and speed. Its slit is small and is not restricted by the shape. It is a non-contact cutting method. The cutting end is smooth without burrs and few deformations. .
With the technological innovation in recent years, the fiber laser cutting machine has made great progress in the field of high power, and has made a major breakthrough in the cutting of the metal thick plate field.
