First of all, the transmission mode of fiber laser cutting machine and CO2 metal laser cutting machine is different. Unlike CO2, fiber laser is not transmitted through mirrors, which makes fiber laser technology have no scope limitation between mirrors. Similarly, compared with the gas cutting system with the same power, the system is more compact due to the bending ability of the optical fiber.
The electro-optical conversion efficiency of the fiber laser cutting machine is far higher than that of the CO2 metal laser cutting machine. Users can use the fiber laser cutting machine to achieve higher power efficiency, about 25% to 30%, which is three to five times the actual utilization rate of the carbon dioxide cutting system of the laser cutting machine brand. The energy efficiency of the fiber laser cutting machine is more than 90% higher than that of the carbon dioxide cutting system.
In terms of maintenance, the high-power CO2 metal laser cutting machine needs regular maintenance, such as the calibration of the mirror and the maintenance of the resonator. The fiber laser cutting machine is maintenance free later.
Due to the short wavelength characteristics of the fiber laser cutting machine, some non-conductive metal materials, as well as brass and copper, are easier to absorb the fiber laser beam. Because the optical fiber laser beam is more concentrated and the light spot is smaller, the cutting speed of the optical fiber laser cutter is faster when cutting thin plates and medium thick plates. When cutting materials up to 6mm thick, the cutting speed of the 1.5KW fiber laser cutting system is equivalent to that of the 3KW CO2 laser cutting system.
