What is the Difference Between Fiber Laser Cutting Machine and CO2 Laser Cutting Machine?

Due to its superior performance, the fiber laser cutting machine has gradually conquered the city and has gradually replaced the carbon dioxide laser cutting machine and has become the mainstream equipment for industrial processing. Below we mainly look at the difference between fiber laser cutting machine and carbon dioxide laser cutting machine?

1. Different luminescent media

Carbon dioxide laser cutting machine, gas is the medium that generates the laser beam, and the beam is transmitted through the mirror. Fiber lasers work through diodes and fiber optic cables. Multiple diodes are pumped to generate a laser beam, which is then transmitted to the laser cutting head through a flexible fiber optic cable instead of a mirror.

2. The appearance of fiber laser cutting machine is more compact

Due to the different laser transmission structure, the fiber laser cutting machine with the same power in appearance size is more compact than the carbon dioxide laser cutting machine, thus saving the workshop space.

3. The conversion efficiency of electro-optical fiber laser cutting is higher

With the complete solid-state digital module and single design of the fiber laser, the fiber laser cutting machine has an electro-optical conversion efficiency higher than that of the carbon dioxide laser cutting. The actual general utilization rate of each power supply unit of the carbon dioxide laser cutting machine is about 8% to 10%, while for the fiber laser cutting machine, this value is about 25% to 30%. The overall energy consumption of the fiber laser cutting system is higher than that of carbon dioxide cutting. The system is about 3 to 5 times less, making the energy efficiency greatly improved.

4. The processing effect of fiber laser cutting machine is better

Fiber lasers have short wavelength properties that increase the absorption of the beam by the material being cut, and enable cutting of materials such as brass and copper as well as non-conductive materials. When cutting materials as thick as 6mm, the cutting speed of a 1.5kW fiber laser cutting machine is equivalent to that of a 3kW CO2 laser cutting machine.

5. The maintenance cost of fiber laser cutting machine is lower

The carbon dioxide laser cutting machine uses gas as the luminous medium. Due to the purity of carbon dioxide gas, the resonant cavity will be polluted and needs to be cleaned regularly. The mirror needs to be maintained and calibrated, so the daily maintenance workload is larger. For a multi-kilowatt carbon dioxide laser cutting machine, this item requires at least tens of thousands of yuan per year. In general, fiber laser cutting is more environmentally friendly and convenient in the daily maintenance of equipment.

6. Different cutting materials

Fiber laser cutting machine is more suitable for cutting metal materials, such as: aluminum, carbon steel, stainless steel, iron, copper, etc. The CO2 laser cutting machine is more suitable for cutting non-metallic materials, such as: leather, cloth, plastic, acrylic, wood, etc.
