What is a fiber laser cutting machine and what does it do?
Fiber laser cutting machine is a laser cutting machine that uses fiber laser generator as light source.
Fiber laser is a new type of fiber laser developed in the world. It outputs a high-energy-density laser beam and concentrates it on the surface of the workpiece, causing the area on the workpiece illuminated by the ultra-fine focus spot to instantly melt and vaporize. The spot is moved through a CNC mechanical system. Automatic cutting can be realized according to the irradiation position, with fast speed and high precision.
Compared with bulky gas lasers and solid lasers, it has obvious advantages and has gradually developed into an important candidate in high-precision laser processing, lidar systems, space technology, laser medicine, and other fields.
The fiber laser cutting machine can be used for both plane cutting and bevel cutting, with neat and smooth edges. It is suitable for high-precision cutting such as metal plates. At the same time, with the addition of a robotic arm, it can perform three-dimensional cutting to replace the original imported five-dimensional cutting machine—axis laser. Compared with ordinary carbon dioxide laser cutting machines, it saves space and gas consumption and has a high photoelectric conversion rate. It is a new product that is energy-saving and environmentally friendly and is also one of the world's leading technological products.
Advantages of fiber laser cutting machine over CO2 laser cutting machine:
1) Excellent beam quality: smaller focused spots, finer cutting lines, higher work efficiency, and better processing quality.
2) Extremely high cutting speed: 2 times that of CO2 laser cutting machines with the same power.
3) Extremely high stability: Using the world's top imported fiber lasers, the performance is stable and the service life of key components can reach 100, 000 hours.
4) Extremely high electro-optical conversion efficiency: The photoelectric conversion efficiency of fiber laser cutting machines reaches about 30%, which is 3 times higher than that of CO2 laser cutting machines. It is energy-saving and environmentally friendly.
5) Extremely low cost of use: The power consumption of the whole machine is only 20-30% of similar CO2 laser cutting machines.
6) Meager maintenance costs: no laser working gas; optical fiber transmission, no need for reflective lenses; can save a lot of maintenance costs.
7) The product is easy to operate and maintain: optical fiber transmission, no need to adjust the optical path.
8) Super flexible light guide effect: small size, compact structure, easy to meet flexible processing requirements.
Of course, compared with carbon dioxide laser cutting machines, the cutting range of optical fibers is relatively narrow. Because of the wavelength, it can only cut metal materials, and non-metals are not easily absorbed by it, thus affecting its cutting range.
Advantages compared with YAG laser cutting machine:
1) Cutting speed: The speed of the fiber laser cutting machine is 4-5 times that of YAG, which is suitable for mass processing and production.
2) Cost of use: The cost of use of a fiber laser cutting machine is less than that of YAG solid laser cutting.
3) Photoelectric conversion efficiency: The photoelectric conversion efficiency of fiber laser cutting machines is about 10 times that of YAG.
The price of the corresponding fiber laser is relatively high. Hence, the price of the fiber laser cutting machine is much higher than that of the YAG laser cutting machine, but much lower than that of the carbon dioxide laser cutting machine. But its price/performance ratio is indeed the highest among the three.
