The reason why fiber laser cutting machines can quickly establish a foothold in the market and gradually replace traditional cutting processes is due to their unique advantages in various aspects. So what is their excellence? Let's compare the CO2 laser cutting machine with the YAG laser cutting machine!

1、 Fiber laser cutting machine VS Co2 laser cutting machine

1. From the perspective of processing

On the one hand, CO2 laser cutting machines have a wide cutting range and can cut thicker metal plates, as well as high reflective materials such as aluminum plates; For non-metallic materials such as acrylic, wood, PVC, etc., the CO2 laser cutting machine can cut a thickness of up to 60 millimeters. And the CO2 laser cutting machine uses continuous laser, which has a smooth cutting surface and good cutting quality during cutting.

On the other hand, although CO2 laser cutting machines cut relatively fine seams, their speed is very slow when processing thick plates. In terms of sheet metal processing, the cutting speed of the same power fiber laser cutting machine is 2-3 times higher than that of CO2, and the cutting section is smooth. In addition, the beam has a large divergence and is not suitable for large format processing.

2. From a cost perspective

The maintenance cost and processing cost during the use of CO2 laser cutting machines are relatively high. Not only are the front and rear mirrors expensive, but the lifespan of turbine bearings is only 8000 hours, and the replacement cost reaches 80000 yuan per pair. At the same time, CO2 laser cutting machine processing will generate gas consumption, and the photoelectric conversion rate is only 8% -10%. The fiber laser cutting machine has almost no consumables during processing, and its photoelectric conversion rate can reach 30%, which is relatively energy-saving and energy-saving.

3. From a maintenance perspective

The laser structure of CO2 laser cutting machine is complex, inconvenient to maintain, and requires high operating requirements. However, fiber laser cutting machine maintenance is relatively simple, and can withstand harsh working environments. It has a high tolerance for dust, vibration, impact, humidity, and temperature.

2、 Fiber laser cutting machine VS YAG laser cutting machine

1. From the perspective of processing

The purchase cost of YAG laser cutting machine is relatively low, and it can cut high reflective materials, such as non-ferrous metal materials that cannot be cut by fiber laser cutting machines such as aluminum and copper. However, YAG laser cutting machines are almost exclusively used for low-power laser cutting, which can only cut thin sheet materials below 8mm. Compared to fiber laser cutting machines, the cutting efficiency is much slower and lower than that of fiber optics. Fiber laser technology can achieve very high power in very small packages, thus occupying a small area and saving space.

2. From a cost perspective

YAG laser is a type of laser that has been developed for decades, with mature technology, so the price of YAG laser cutting machines is relatively cheap. But with the popularization of fiber lasers, this advantage is becoming increasingly weak. In addition, the power consumption during the processing of YAG laser cutting machines is relatively high

3. From a maintenance perspective

Due to the absence of optical lenses in the resonant cavity of fiber lasers, which have the advantages of no adjustment, maintenance, and high stability, device maintenance and replacement are relatively simple. This is incomparable to traditional YAG lasers.

Overall, the advantages of fiber laser cutting machines are relatively obvious. However, each of the three types of laser cutting machines has its own characteristics, and in practical applications, a reasonable selection should be made based on one's own cutting needs and budget.
