The Principle of Fiber laser VS. CO2 laser
Fiber laser cutting machine is a laser cutting machine which using fiber laser generator as a light source.it is a new development of cutting technology
It can generate a new type of fiber laser which have a high-energy density laser beam And the laser beam gather on the surface of the workpiece, so that the area on the workpiece irradiated by the ultra-fine focus spot instantly melts and vaporizes.while controlled by cnc system to move the position fast and achieve automatic cutting
CO2 laser, The laser power is sourced from the laser tube to generate light, then it is refracted by several mirrors to transmit light to the laser head. focuses light into a point by the focusing lens which fixed on the laser head,The point with high temperature sublimate materials into gas instantly
Nowadays,CO2 laser is used in non-metal laser marking field commonly. While,Fiber laser has a wide range of applications, including laser fber communication, industrial shipbuilding, automobile manufacturing, sheet metal processing, laser engraving, medical equipment and so on.
Why Fiber laser is much more useful than CO2 laser, Which technology is right for your application?
The fiber consumes much less electricity,For each power unit of carbon dioxide cutting system, the actual general utilization rate is about 8% to 10%. As for the fiber laser cutting system,The power consumption of the whole machine is only 20-30% of the same type CO2 laser cutting machine.the overall energy consumption of the fiber cutting system is about 3 to 5 times less than that of the carbon dioxide cutting system, which makes the energy efficiency increased to more than 80%.
Extremely high cutting speed
Fiber laser cutting speed is almost double than CO2 laser ,because the beam is more readily absorbed and not reflected. For example, cutting aluminum and thinner, using ABR as an assist gas can produce speeds 3x higher than CO2. When cutting materials of thickness to 6mm, the cutting speed of 1. 5kw fiber laser cutting system is equivalent to that of 3KW carbon dioxide laser cutting system,
Low maintenance cost
CO2 laser sources CO2 gas as luminous medium,Due to the purity problem of CO2 gas, the cavity will be polluted and need to be cleaned regularly. Reflected mirror needs maintenance and calibration . It costs at least $20,000 a year for kilowatt level CO2 laser.In addition, many CO2 cuts require high-speed axial-flow turbines to deliver laser gas, and turbines require maintenance and renovation. Overall,compared to CO2 laser,fiber laser is more friendly and environmentally
Although CO2 laser have very strong cutting ability, fiber laser is more fast, more widely range of work materials and lower use cost.
