1. It has higher electro-optical conversion efficiency, which is more than 30%. The low-power laser machine has no need of a chiller. The air cooling will greatly save power consumption during operation, save costs, and achieve the highest manufacturing efficiency, 2. It only requires electrical energy during operation without additional gas, which has the lowest operation and maintenance costs, 3. It adopts semiconductor modular and redundant design. There is no optical lens in the resonant cavity, no start-up time, and it has the advantages of no adjustment, maintenance, and high stability. It reduces the cost of accessories and maintenance time, 4. The fiber laser wavelength is 1.064 microns, which makes the laser beam with high quality and high power density. It is very conducive to the absorption of metal materials, 5. The optical transmission of the whole machine is through optical fiber, no complicated light guide system such as reflecting mirror is needed, the optical path is simple, the structure is stable, and the external optical path is maintenance-free., 6. The cutting head contains a protective lens, which makes the consumption of expensive consumables such as focusing lenses extremely small, 7. The light is exported through the optical fiber, which makes the design of the mechanical system very simple, and it is very easy to integrate with the robot or multi-dimensional workbench, 8. After the laser is added with the optical shutter, it can be multi-machine, split through the optical fiber, divided into multiple channels and work simultaneously, easy to expand the function, easy and simple to upgrade.
With the CNC control system, the fiber laser cutter is equipped with a laser generator to dope the pump material into the optical fiber, and the laser of a specific wavelength emitted by the semiconductor laser is coupled to make the optical fiber generate laser light. Then, the machine converges the laser beam into a small diameter spot to form a beam of high energy density and extremely bright light, which acts on the metal to be cut, which causes the temperature of the metal at the laser irradiation point to be sharp it rises and reaches the vaporization temperature instantaneously, causing evaporation and forming holes. And the machine uses this as the starting point, according to the shape requirements of the part to be cut, the laser beam and the part are moved relative to each other according to a certain trajectory to form a slit. At the same time, the auxiliary gas blowing device is used to remove the slag.
