The fiber laser cutting machine uses a high-energy-density laser beam for cutting, it brings smooth and flat cutting surface, no need the secondary processing and grinding. By using a digital control system, the generation and adjustment of cutting trajectories can be automatically completed. Because of the high energy conversion efficiency and low energy consumption, it can not only reduce processing costs, but also achieve environmental protection and energy saving. Compared with traditional cutting methods, fiber laser cutting has outstanding advantages, and has gradually become the main equipment in the metal cutting industry.
