The fiber laser cutting machine has been able to gain a fast foothold in the market and replace the traditional cutting technology step by step, because its unique advantages in all aspects, so where is he excellent? We know that the CO2 laser cutting machine and the YAG laser cutting machine are compared.
Contrast reference table for fiber laser, YAG laser and optical fiber laser

Co2 laser cutting machine VS optical fiber laser cutting machine
1. The point of view of processing
On the one hand, CO2 laser cutting machine has wide cutting range, capable of cutting thick metal plates and high reflective materials such as aluminum plates. For non-metallic materials, such as acrylic, wood and PVC, CO2 laser cutting machine can cut 60 mm thick. And the CO2 laser cutting machine is a continuous laser. The cutting surface is smooth and the cutting quality is good.
On the other hand, the CO2 laser cutting machine is very slow, although the cutting seam is fine. The cutting speed of the same power fiber laser cutting machine is 2-3 times higher than that of the CO2, and the cutting section is smooth. In addition, the beam has a large divergence, which is not suitable for the processing of large scale.
2. The cost point of view
The maintenance cost of CO2 laser cutting machine is higher than that of the front end mirror. The cost of the front end mirror is only 8000 hours, and the replacement cost is 80 thousand yuan per pair. At the same time, the CO2 laser cutting machine will produce gas consumption, and the photoelectric conversion rate is only 8%-10%. The optical fiber laser cutting machine is basically processed without consumable material, and its photoelectric conversion rate can reach 30%, and the energy saving and electricity saving is compared.
3. The point of view of maintenance
The CO2 laser cutting machine has complex structure, inconvenient maintenance and high operation requirements, while the fiber laser cutting machine is relatively simple to maintain, and is capable of working in harsh working environments. It has high tolerance to dust, shock, impact, humidity and temperature.

YAG laser cutting machine VS optical fiber laser cutting machine
1. from the point of view of processing
YAG laser cutting machine purchase cost is low, can cut high reflective material, such as aluminum, copper and other optical fiber laser cutting machine can not cut the non-ferrous metal material. But the YAG laser cutting machine almost cuts the small power laser cutting. It can only cut thin plate material less than 8 millimeters. Compared with fiber laser cutting machine, the cutting efficiency is much slower than optical fiber, and the efficiency is relatively low. Optical fiber laser technology can achieve very high power in very small package, so it occupies less space and saves space.
2. from the cost point of view
YAG laser is a kind of laser which has developed for several decades, and the technology is mature, so the price of YAG laser cutting machine is also relatively cheap. But with the popularity of fiber lasers, this advantage is becoming weaker and weaker. In addition, the power consumption of the YAG laser cutting machine is larger.
3. from the point of view of maintenance
Because of the non optical lens in the resonator of the fiber laser, it has the advantages of free adjustment, maintenance free and high stability, so the device maintenance and replacement is relatively simple. This is incomparable to the traditional YAG laser.
When two rounds of PK came down, we found that the advantages of the optical fiber laser cutting machine were more obvious. But the three kinds of laser cutting machines have their own characteristics. In practical applications, they should be chosen according to their own cutting needs and budgets.
