Comparison of fiber laser cutting machine and CO2 laser cutting machine

Posted by sere on February 24th, 2020


Compared with the structure of laser equipment, the co2 laser machine, as the name implies, CO2 gas is the medium that generates laser beams. Compared with CO2 laser cutting machine, fiber laser cutting machine has excellent beam quality, smaller focus spot, making the cutting line more fine, and can achieve better quality processing. There are also cutting bed sizes. In gas laser technology, the reflector must be set within a certain distance, but fiber laser technology has no range limitation. It is even possible to mount a fiber laser next to the plasma cutting head of a plasma cutting bed. Gas cutting technology does not have this option. In addition, when compared with a gas cutting system of the same power, the system appears more compact due to the ability of the fiber to bend.



The most important and significant advantage of comparing fiber cutting technology from electro-optic conversion efficiency is its energy efficiency. Fiber laser cutting system has 3 times higher electro-optical conversion efficiency than CO2 laser cutting. For each power supply unit of the CO2 cutting system, the actual general utilization rate is about 8% to 10%. For fiber laser cutting systems, users can expect higher power efficiency, between 25% and 30%. In other words, the overall energy consumption of the fiber cutting system is about 3 to 5 times less than that of the CO2 cutting system, which makes the energy efficiency increase by about 86%, saves energy and environmental protection, and reduces production costs.
