1. The laser generator is different: carbon dioxide laser is a gas molecular laser, carbon dioxide as a medium, through the mirror in the transmission of light beams. The fiber laser cutting machine is through the diode and fiber optics cable transmission work, a number of diode pump laser beam, and then through the flexible fiber optic cable transmission to the laser cutting head. Carbon dioxide laser technology in the mirror to act in a certain distance, and the laser cutting machine will not be subject to such restrictions.
2. Conversion rate: Fiber laser is the current advanced laser technology, and the solid-state laser generator it uses is more efficient than traditional carbon dioxide lasers. The photoelectric conversion rate of carbon dioxide laser cutting machine is only 8% -10%, while the optical fiber laser cutter can be as high as 30%. That is to say, the overall energy consumption of fiber laser cutting machine is 3-5 times lower than that of carbon dioxide laser cutting machines, which improves energy efficiency by at least 86%, which is very power-saving.
3. Cutting ability: fiber laser has a short wavelength characteristics, thereby improving the absorption of the cutting material on the beam, more suitable for conduction in the soft fiber, compared with the carbon dioxide laser with specular reflection conduction to be flexible, easier to maintain. A 3KW fiber laser cutting machine is equivalent to a 4-5KW carbon dioxide laser cutter in cutting capacity and speed, greatly reducing operating costs.
4. Maintenance cost: carbon dioxide laser structure is relatively complex, The later maintenance cost is relatively high, the carbon dioxide gas laser system should be cleaned and maintained regularly, the reflector should be regularly cleaned and calibrated, and the resonant cavity should also be maintained regularly due to the purity of the CO2 gas. In addition, the turbine that delivers the laser gas is also subject to regular maintenance and renovation, which is very expensive and complicated to maintain in the later stage. The fiber laser cutting machine is more convenient and environmentally friendly in the later maintenance.
With the development of fiber laser cutting machines and their various advantages gradually replace the market of carbon dioxide laser cutting machine, at present, carbon dioxide is mainly cutting non-metallic materials, such as cloth, leather, acrylic, plastic and so on. With the development of fiber laser high power, it is gradually occupying the processing market of thick plates.
