Optical fiber cutting machine is also known as optical fiber laser cutting machine. Through optical fiber transmission, the degree of flexibility has been improved unprecedentedly, with fewer failure points, convenient maintenance and extremely fast speed. Therefore, the optical fiber cutting machine has great advantages when cutting thin plates within 4mm,; However, due to the influence of solid laser wavelength, its quality is poor when cutting thick plates. The wavelength of the fiber laser laser cutting machine is 1.06um, which is not easy to be absorbed by nonmetals, so it cannot cut nonmetallic materials. The photoelectric conversion rate of fiber laser is more than 25%, and the advantages of fiber laser in electricity consumption, supporting cooling system, etc. are quite obvious.
Comparison between optical fiber laser cutting machine and Co2 laser cutting machine:
1. Equipment maintenance cost, CO2 laser cutting machine maintenance cost is huge, not only the front mirror and tail mirror are expensive, but also the life of turbine bearing is only 8000 hours, and the replacement cost reaches 80000 yuan per pair. However, the optical fiber laser cutting machine is maintenance free, basically has no consumables, and is capable of working in harsh environments with high tolerance to dust, shock, impact, humidity and temperature.
2. Compared with the processing cost, CO2 laser cutting machine not only generates gas consumption, but also has a photoelectric conversion rate of only 8% - 10%. The optical fiber laser cutting machine does not need any other consumption when processing, and its photoelectric conversion rate can reach 30%, which is relatively energy-saving.
3 In terms of technology, CO2 laser cutting machine has complex laser structure, high maintenance cost, and large beam divergence in processing, which is not suitable for large format processing. Although the cutting seam is relatively thin, it is very slow in processing thick plates. However, the laser characteristics of the fiber laser cutting machine are characterized by miniaturization, intensification, high brightness and high conversion rate. In thin plate processing, the cutting speed of the fiber laser cutting machine with the same power is 2-3 times higher than that of CO2, and the cutting section is smooth.
Comparison between optical fiber laser cutting machine and YAG laser cutting machine:
1. Scope of work: the optical fiber laser cutting machine not only includes the cutting speed and area of the YAG cutting machine, but also improves the cutting quality;
2. The optical fiber laser cutting machine can achieve the effect of high power with low power, reduce the cost of cutting, and achieve high efficiency with low energy consumption.
3. Realized the significance of operation and maintenance
4. The main advantages of optical fiber cutting machine lie in its transmission medium and light source; The optical fiber laser uses diode as the light source and optical fiber as the transmission medium to transmit lossless optical energy to the laser cutting head.
It is said that the reason why the optical fiber laser cutting machine can quickly gain a foothold in the market and gradually replace the traditional cutting process is precisely because of its various advantages in technology, which provides the necessary technology for the realization of product finishing.
