Fiber laser cutting machines are a new type of laser cutting machine developed in recent years. They use fiber lasers to output high energy density laser beams and concentrate them on the processed material, achieving the effect of automated cutting. Mainly used in carbon steel, stainless steel, silicon steel and other metal materials below 25mm. So, as a new type of laser cutting technology, what are the advantages and disadvantages of fiber laser cutting machines compared to CO2 laser cutting machines?

advantage

1. Good beam quality: The fiber laser cutting machine has smaller focusing spot, finer cutting lines, higher work efficiency, and better processing quality;

2. Fast cutting speed: Fiber laser cutting machines are twice as powerful as CO2 laser cutting machines of the same power;

3. High stability: Using Wuhan Ruike fiber laser, the performance is stable, and the service life of key components can reach 100000 hours;

4. The photoelectric conversion efficiency of the fiber laser cutting machine is extremely high: the photoelectric conversion efficiency of the fiber laser cutting machine is about 30%, which is three times higher than the CO2 laser cutting machine, energy-saving and environmentally friendly;

5. Low operating cost: The power consumption of the entire machine is only 20-30% of that of similar CO2 laser cutting machines;

6. Low maintenance cost: fiber optic transmission, no need for reflective lenses; Basically maintenance free, which can save a lot of maintenance costs;

7. Easy to operate: Fiber optic transmission, no need to adjust the optical path; After simple training, the machine can be operated and used, which is very convenient.

shortcoming

At present, most of the core and key technologies of fiber lasers are in the hands of one or two manufacturers in Europe, America, and other countries. Therefore, most machines are expensive, with prices of over 1.5 million yuan for most machines and around 500000 yuan for low-power ones. During cutting, due to the fine slitting of the fiber, the gas consumption is huge (especially during nitrogen cutting). Additionally, fiber laser cutting machines are difficult to cut high reflective materials such as aluminum and copper plates, And the speed becomes less pronounced when cutting thick plates above 30mm.

Despite the advantages and disadvantages of fiber laser cutting machines mentioned above, overall, the advantages of fiber laser cutting machines outweigh the disadvantages. Such achievements have only been developed in a few years, and there is still broader development space for the research and development of fiber laser technology. I believe that in the future, fiber laser cutting machines will bring us more technological surprises and processing breakthroughs!
