Comparison between fiber laser cutter and CO2 laser cutter

Comparison between fiber laser cutting machine and CO2 laser cutting machine.

Working principle

Optical fiber laser cutting machine:

Fiber laser cutting machine is a laser cutting machine which uses fiber laser generator as light source.

CO2 laser cutting machine:

Laser cutting machine is a laser beam that is emitted from a laser and is focused on a high power density through the optical system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high pressure gas which is coaxial with the beam will blow away or melt the metal.

comparative analysis

Processing cost:

CO2 laser cutting machine not only produces gas consumption, but also has a photoelectric conversion rate of only 8%-10%. Fiber laser cutting machine does not require any other consumption, and its photoelectric conversion rate can reach 30%, which is more energy saving and electricity saving.

Equipment maintenance cost:

The maintenance cost of the CO2 laser cutting machine is great. Not only the front mirror tail mirror is expensive, but the turbine bearing life is only 8000 hours, and the replacement cost is 80 thousand yuan per pair. However, the optical fiber laser cutting machine has no maintenance, basically no consumables, and can be competent for a bad working environment. It has a high tolerance to dust, shock, impact, humidity and temperature.

Technical aspects:

The CO2 laser cutting machine has complex structure and high maintenance cost. Moreover, the laser beam is highly divergent and not suitable for large format machining. Although the cutting seam is relatively thin, it is very slow when processing thick plate. However, the laser cutting machine is characterized by miniaturization, intensive, high brightness and high conversion. The laser cutting machine with equal power is 2-3 times higher than the CO2, and the cutting section is smooth.

Through the above analysis, do you know the difference between them?
