What Are the Advantages of Fiber Laser Cutter?

Since fiber laser entered the field of metal cutting as a subversive industry disruptor, it has re-established new rules for laser cutting, refreshed relevant definitions, and changed the development direction of laser cutting technology in the world, becoming the leader of current laser cutting technology and frontrunner. So what are the advantages of fiber laser cutter compared to traditional CO2 laser cutting machine?


1. Laser medium consumption of fiber laser cutter


The fiber laser uses the rare earth element ytterbium as the luminescent medium, which has no consumption for long-term use; the CO2 laser uses high-purity helium, nitrogen, and carbon dioxide as the luminescent medium, and it consumes when it works. Therefore, fiber lasers are less expensive to operate.


2. The power attenuation problem of fiber laser cutter


Since the CO2 laser uses high-purity helium, nitrogen, and carbon dioxide, its resonator will be polluted, and the inside of the resonator will be aging after long-term use. Generally, power attenuation will occur after a few years of use, and this will lead to Cutting power is reduced. For this reason, the CO2 laser resonator needs to be cleaned regularly, which is expensive. Fiber lasers do not have resonator contamination and aging problems, so there is no power attenuation in long-term use.


3. Laser speed comparison of fiber laser cutter


The wavelength of fiber laser is 1.06 μm, and the wavelength of CO2 laser is 10.6 μm. Since the smaller the wavelength, the higher the metal absorptivity, the faster the cutting speed. Therefore, a laser cutter has a significant speed advantage when cutting metal materials.


4. The electro-optical conversion rate of the fiber laser cutter is high


The electro-optical conversion rate of fiber laser is 30%-35%, and the electro-optical conversion rate of CO2 laser is only 10%-12%. Therefore, for the same power laser, the fiber laser saves more power. Taking a 2000W laser as an example, the input power of the fiber laser is 7.5KW, and the input power of the CO2 laser is 20KW.


5. The chiller power consumption of the fiber laser cutter


Due to the high electro-optical conversion rate of the fiber laser, the fiber laser generates less heat, and the chiller used to cool the fiber laser consumes less energy. This is unmatched by CO2 lasers.


Laser cutting is easy to realize the automation of the cutting process control, which greatly shortens the production cycle, reduces the manufacturing cost and improves the product quality. Now it has partially replaced stamping and machining techniques. However, laser cutting technology is not only used as cutting energy for cutting, but also has many other application fields.
