Fiber laser cutting machine is a new type of laser cutting machine developed in recent years. It uses a fiber laser to output a laser beam with high energy density and concentrate it on the processed material to achieve the effect of automatic cutting. It is mainly used for carbon steel, stainless steel, silicon steel and other metal materials below 25mm. So, as a new laser cutting technology, what are the advantages and disadvantages of fiber laser cutting machine compared with CO2 laser cutting machine?

What are the advantages and disadvantages of optical fiber laser cutting machine?

advantage

1. Good beam quality: optical fiber laser cutting machine has smaller focus, thinner cutting line, higher working efficiency and better processing quality;

2. Fast cutting speed: the optical fiber laser cutting machine is twice as fast as the CO2 laser cutting machine with the same power;

3. High stability: Chuyu Optoelectronic laser has stable performance, and the service life of key components can reach 100000 hours;

4. The electro-optic conversion efficiency is very high: the electro-optic conversion efficiency of the optical fiber laser cutting machine is about 30%, three times that of the CO2 laser cutting machine, which is energy saving and environmental protection;

5. Low operation cost: the energy consumption of the whole machine is only 20-30% of that of the same CO2 laser cutting machine;

6. Low maintenance cost: optical fiber transmission, no reflector; Basically maintenance free, which can save a lot of maintenance costs;

7. Simple operation: optical fiber transmission, no need to adjust the optical path; Simple training can be carried out after operating the machine, which is very convenient.

shortcoming

At present, most of the core technologies and key technologies of fiber lasers are in the hands of one or two manufacturers in Europe and the United States, so most of the machines are expensive. Most machines cost more than 1.5 million yuan, while low-power machines cost about 500000 yuan. Because the optical fiber slit is very thin, and the gas consumption is large (especially when nitrogen cutting), in addition, the optical fiber laser cutter is difficult to cut aluminum, copper and other high reflectivity materials, and the speed is not obvious. Cut plates with a thickness of more than 30mm.

Even though the fiber laser cutting machine has the above disadvantages, the advantages of the fiber laser cutting machine can make up for the disadvantages. Otherwise, such achievements would not have been achieved in a few years. The research and development of fiber laser technology still has broad development space. We believe that in the future, the optical fiber laser cutting machine will bring us more technical surprises and processing breakthroughs!
