Introduction To Fiber Laser Cutting Machine

Fiber laser is a new type of fiber laser developed internationally that outputs a high energy density laser beam and gathers it on the surface of the workpiece, causing the area illuminated by the ultra-fine focal spot on the workpiece to instantly melt and vaporize. Automatic cutting is achieved by moving the spot illumination position through a CNC mechanical system. Compared with bulky gas lasers and solid-state lasers, they have obvious advantages and have gradually developed into important candidates in fields such as high-precision laser processing, LiDAR systems, space technology, and laser medicine.
The fiber laser cutting machine can perform both flat cutting and oblique cutting, with neat and smooth edges, suitable for high-precision cutting of metal plates and other materials. Additionally, the mechanical arm can perform three-dimensional cutting instead of the original imported five axis laser. Compared to ordinary carbon dioxide laser cutting machines, they save more space and gas consumption, have a high photoelectric conversion rate, and are energy-saving and environmentally friendly new products. They are also one of the world's leading technological products.
Advantages of fiber laser cutting machines over CO2 laser cutting machines:
1) Excellent beam quality: smaller focusing spot, finer cutting lines, higher work efficiency, and better processing quality;
2) Extremely high cutting speed: twice the same power CO2 laser cutting machine;
3) Extremely stable: Adopting world-class imported fiber lasers, with stable performance and a lifespan of up to 100000 hours for key components;
4) Extremely high electro-optical conversion efficiency: The photoelectric conversion efficiency of the fiber laser cutting machine is about 30%, which is three times higher than that of the CO2 laser cutting machine, energy-saving and environmentally friendly;
5) Extremely low usage cost: The power consumption of the entire machine is only 20-30% of that of similar CO2 laser cutting machines;
6) Extremely low maintenance cost: no laser working gas; Fiber optic transmission without the need for reflective lenses; Can save a lot of maintenance costs;
7) Easy operation and maintenance of the product: optical fiber transmission, no need to adjust the optical path;
8) Super strong flexible light guiding effect: compact size, compact structure, easy to meet flexible processing requirements.
Of course, compared to carbon dioxide laser cutting machines, the cutting range of optical fibers is relatively narrow. Due to the wavelength, it can only cut metal materials and is not easily absorbed by non-metals, thus affecting its cutting range.
Advantages compared to YAG laser cutting machines:
1) Cutting speed: The speed of the fiber laser cutting machine is 4-5 times that of YAG, suitable for large-scale processing and production
2) Usage cost: The usage cost of fiber laser cutting machines is lower than that of YAG solid laser cutting
3) Optoelectronic conversion efficiency: The photoelectric conversion efficiency of fiber laser cutting machine is about 10 times that of YAG
The price of corresponding fiber lasers is relatively high, so the price of fiber laser cutting machines is much higher than that of YAG laser cutting machines, but much lower than that of carbon dioxide laser cutting machines. But its sex ratio is indeed the highest among the three.
