We believe that everyone has heard of the laser gas cutting machine. Many people believe that the fiber laser cutting machine, Co2 laser cutting machine and YAG laser cutting machine are different. Then, Tianchen Laser Xiaobian will talk about the differences between the three, so that when you choose a laser cutting machine, you can also choose the best one for yourself.
1、 Optical fiber laser cutting machine and Co2 laser cutting machine
1. Processing angle: CO2 laser cutting machine has a wide cutting range and can cut thick metal plates, aluminum plates and other highly reflective materials; For non-metallic materials such as acrylic, wood and PVC, the cutting thickness of CO2 laser cutting machine can reach 60mm. And CO2 laser cutting machine adopts continuous laser, so the cutting surface is smooth and the cutting quality is good. On the other hand, although the CO2 laser cutting machine has a relatively thin cutting seam, it is very slow in processing thick plates. In thin plate processing, the cutting speed of the same power fiber laser cutter is 2-3 times higher than that of CO2, and the cutting section is smooth. In addition, the beam divergence is large, which is not suitable for large format processing.
2. The maintenance cost and processing cost of CO2 laser cutting machine in use are high. Not only is the front mirror and tail mirror expensive, but the life of turbine bearing is only 8000 hours, and the replacement cost reaches 80000 yuan per pair. At the same time, CO2 laser cutting machine will produce gas consumption during processing, and the photoelectric conversion rate is only 8% – 10%. The optical fiber laser cutting machine basically has no consumables during processing, and its photoelectric conversion rate can reach 30%, which is relatively energy-saving.
3. Maintenance angle The laser of CO2 laser cutting machine has complex structure, inconvenient maintenance and high operation requirements, while the optical fiber laser cutting machine is relatively simple to maintain, and can be competent for harsh working environment, and has a high tolerance for dust, shock, impact, humidity and temperature.
2、 Optical fiber laser cutting machine PK YAG laser cutting machine
1. The purchase cost of YAG laser cutting machine for processing angle is low, and it can cut highly reflective materials, such as aluminum, copper and other non-ferrous materials. However, YAG laser cutting machine is almost a uniform low-power laser cutting machine, which can only cut sheet materials below 8mm. Compared with fiber laser cutting machine, the cutting efficiency is much slower and lower than that of fiber laser cutting machine. Fiber laser technology can achieve very high power in a very small package, so it occupies a small area and saves space.
2. From the perspective of cost, YAG laser is a laser that has been developed for decades, and the technology is mature, so the price of YAG laser cutting machine is relatively cheap. However, with the popularization of fiber lasers, this advantage is becoming weaker and weaker. In addition, YAG laser cutting machine consumes more power during processing.
3. Maintenance angle Since there is no optical lens in the resonant cavity of the fiber laser, it has the advantages of no adjustment, no maintenance and high stability, so component maintenance and replacement are relatively simple. This is incomparable to the traditional YAG laser. By comparison, the advantages of fiber laser cutting machine are obvious. However, the three types of laser cutting machines actually have their own characteristics, and should be selected reasonably according to their own cutting needs and budget in practical application.
