Laser cutting is the best cutting method among all kinds of cutting techniques that people have mastered at present. Compared with traditional cutting, laser cutting has the advantages of small thermal deformation, high cutting precision, small noise, no pollution, easy to realize automatic cutting, and the processing cost is 50% less than that of mechanical processing. Fiber laser cutting machine is the most advanced fiber laser output high energy density laser beam, and focus on the workpiece surface, is the workpiece by ultra-fine focus spot irradiation area instantaneous melting and gasification, through the CNC mechanical system moving spot irradiation position and automatic cutting. It is a set of the most advanced fiber laser technology, CNC technology, precision machinery technology in one of the high-tech equipment.
