technology is its energy efficiency. With fiber laser complete solid state digital module, single design, fiber laser cutting system has higher electro-optical conversion efficiency than carbon dioxide laser cutting. The actual general utilization rate for each power unit of a CO2 cutting system is about 8 to 10 percent. For laser cutting systems, users can expect higher power efficiency, in the range of 25 to 30 percent. In other words, fiber cutting systems as a whole consume about three to five times less energy than carbon dioxide cutting systems, resulting in an energy efficiency improvement of more than 86 percent. Laser cutting machine is sheet metal parts processing can greatly improve the labor productivity of advanced equipment, with high precision processing parts, short processing cycle, processing without the traditional stamping die replacement, you can process arbitrary complex parts and other advantages, so as to be used by more and more switching equipment manufacturing enterprises. Laser cutting machine is now the result of technological development, now the continuous development of laser technology is mature, it has been used in many industries, fiber laser cutting machine is widely used in all walks of life, because its high efficiency, high precision characteristics can meet the increasingly progressive processing requirements of all walks of life. Fiber laser is a new laser device developed in recent years. It is also one of the hot technologies in photoelectric information field at home and abroad. Because of the advantages of optical mode and service life, fiber laser has become the representative of a new generation of solid lasers, which has been widely studied and developed rapidly at home and abroad, and has broad prospects for development. Laser cutting machine is a wonderful work in the development of laser technology, the rapid development of fiber laser technology has also driven the development of fiber laser cutting machine. Fiber laser cutting machines are faster and cost 20 to 30 percent less than traditional equipment. Fiber lasers also reduce the use of lenses, greatly reducing production and maintenance costs.
