Laser cutting machine big PK! Optical fiber, CO2, YAG, who do you choose?

The reason why the fiber laser cutting machine can quickly gain a foothold in the market and gradually replace the traditional cutting process is because it has unique advantages in all aspects, so where does it stand out? Let's compare CO2 laser cutting machine and YAG laser cutting machine!

1. Fiber laser cutting machine PK CO2 laser cutting machine

1. From the processing point of view

On the one hand, The CO2 laser cutting machine has a wide cutting range, which can cut thick metal plates, aluminum plates and other highly reflective materials; for non-metallic materials such as acrylic, wood, and PVC, the CO2 laser cutting machine can cut up to 60mm in thickness. The CO2 laser cutting machine adopts continuous laser, the cutting surface is smooth, and the cutting quality is good.

On the other hand, although the cutting seam of the CO2 laser cutting machine is relatively thin, the processing speed of thick plates is very slow. In thin plate processing, the cutting speed of the same power fiber laser cutting machine is 2-3 times higher than that of CO2, and the cutting part is smooth. In addition, the beam has a large divergence, which is not suitable for large format processing.

2. From a cost point of view

The maintenance cost and processing cost of CO2 laser cutting machine are high. Not only are the front and rear mirrors expensive, but the service life of the turbine bearings is only 8,000 hours, and the replacement cost is 80,000 yuan per pair. At the same time, the CO2 laser cutting machine will generate gas consumption, and the photoelectric conversion rate is only 8%-10%. The fiber laser cutting machine has almost no consumables, the photoelectric conversion rate can reach 30%, and the energy saving effect is more economical.

3. From the perspective of maintenance

CO2 laser cutting machine has complex structure, inconvenient maintenance and high operation requirements, while fiber laser cutting machine is simple to maintain and can withstand harsh work Environment, with high tolerance to dust, vibration, shock, humidity, temperature, etc.

2. Fiber laser cutting machine PK YAG laser cutting machine

1. From the processing point of view

YAG laser cutting The purchase cost of the machine is low, and it can cut high-reflective materials, such as aluminum, copper and other non-ferrous metal materials, but the fiber laser cutting machine cannot cut. However, the YAG laser cutting machine can only cut thin plates of 8 mm or less, and the cutting efficiency is much slower than that of the 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 a cost point of view

YAG laser is a kind of mature technology after decades of development, so the price of YAG laser cutting machine is relatively cheap. But with the popularity of fiber lasers, this advantage is getting weaker and weaker. In addition, the power consumption of the YAG laser cutting machine is also very large.

3. From the perspective of maintenance

Because there is no optical lens in the resonator of the fiber laser, it has no adjustment and no adjustment. The advantages of high maintenance and stability, so the maintenance and replacement of the equipment is relatively simple. This is unmatched by traditional YAG lasers.

After two rounds of PK, we found that the advantages of fiber laser cutting machine are obvious. However, these three laser cutting machines have their own characteristics. In practical applications, we should make reasonable choices based on our reduction needs and budget.
