Currently, in the metal processing market, fibre laser cutting machines have gradually replaced CO2 laser cutting machines and traditional means of processing, becoming the mainstream equipment in sheet metal processing. What is the difference between fibre laser cutting machines and CO2 laser cutting machines, and what are the advantages?
1.Different luminous medium
With CO2 laser cutting machines, the gas is the medium that produces the laser beam and transmits the beam through a reflector. Fibre lasers, on the other hand, work with diodes and fibre optic cables for transmission. Multiple diodes are pumped to produce the laser beam, which is then transmitted to the laser cutting head through a flexible fibre optic cable, rather than transmitting the beam through a reflector.
2.Fibre Laser Cutter Cutting Machine with more Space Saving
Due to the different laser transmission structures, fibre laser cutting machine with the same power is more compact than Co2 laser cutting machine in terms of appearance and size, thus saving plant space.
3.Fiber Laser Cutting Machine Electricity And Light Conversion Efficiency Is Higher
With the fibre laser's complete solid-state digital module and single design, the fibre laser cutting machine has a higher electro-optical conversion efficiency than the CO2 laser cutting machine. The overall energy consumption of fibre laser cutting systems is about 3 to 5 times less than that of the CO2 cutting system, making the energy efficiency increased to more than 86%.
4.Fibre Laser Cutting Machine with Better Processing Results
The short wavelength of the fibre laser improves the absorption of the beam by the material being cut and enables the cutting of materials such as brass and copper as well as non-conductive materials. When cutting materials as thick as 6mm, the 1.5kW fibre laser cutting machine can cut at a speed equivalent to that of a 3kW CO2 laser cutting machine.
5.Lower maintenance costs for fibre laser cutting machines
The CO2 laser cutting machine uses gas as the light-emitting medium. Due to the purity of CO2 gas, the resonant cavity is contaminated and needs to be cleaned regularly, and the reflector needs to be maintained and calibrated, resulting in more routine maintenance work. For a CO2 laser cutting machine of several kilowatts, this requires at least $20,000 per year. Overall, fibre laser cutting is more environmental- friendly and convenient in terms of routine maintenance of equipment.
