The difference between fiber cutting laser and CO2 laser cutting machine


Laser cutting has gradually become the mainstream way of industrial processing. Different lasers are used, and the processing results are not the same. CO2 lasers and fiber lasers use laser cutting machines that use different processes because of the different physical characteristics of the lasers. Let's take a look at the differences between them.

 

The CO2 laser cutting machine is mainly used for glass cutting on non-metal such as wood, acrylic sheet, and PP plexiglass. Therefore, the CO2 laser cutting machine is also called a non-metal laser cutting machine. The fiber laser cutting machine is mainly used in the metal industry such as copper and silver, so it is also called metal laser cutting machine.

 

From the perspective of processing

 

1. On the one hand, CO2 laser cutting machine has a wide cutting range, which can cut thick metal sheets and high reflective materials such as aluminum sheets. For non-metallic materials such as acrylic, wood materials, PVC and other materials, CO2 laser cutting machine can cut up to 60 thickness. Millimeter. And the CO2 laser cutting machine uses a continuous laser, which has a smooth cutting surface and good cutting quality.

 

On the other hand, although the CO2 laser cutting machine has a relatively small cutting seam, it is very slow in processing thick plates. In the processing of thin plates, the same power fiber laser cutting machine has a cutting speed of 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 the perspective of cost

 

The maintenance cost of the maintenance cost of the CO2 laser cutting machine is high, and not only the front mirror tail mirror is expensive, but also the life of the turbine bearing is only 8000 hours. At the same time, CO2 laser cutting machine will produce gas consumption when processing, and the photoelectric conversion rate is only 8%-10%. Fiber laser cutting machine has almost no consumables when processing, and its photoelectric conversion rate can reach 30%, which is more energy-saving and energy-saving.

 

3. From a maintenance perspective

 

The laser structure of CO2 laser cutting machine is complex, it is inconvenient to maintain and has high operation requirements. The fiber laser cutting machine is simple to maintain and can be used in harsh working environment. It has high tolerance to dust, shock, shock, humidity and temperature. degree.
