Why choose fiber laser cutting machine? You will understand after reading these points.

At present, in the metal processing market, fiber laser cutting machine has gradually replaced CO2 laser cutting machine and traditional processing means, become the mainstream equipment in sheet metal processing. Fiber laser cutting machine compared with CO2 laser cutting machine, what are the differences, and what are the advantages?

CO2 laser cutting machine, the gas is the medium to produce the laser beam, through the mirror transmission of the beam. Fiber lasers are pumped by diodes and fiber optic cables. The beam is then sent through a flexible fiber optic cable to the laser cutting head, rather than through a mirror. The maintenance cost is large, the front mirror and tail mirror are expensive, the life of turbine bearings is short, and the replacement cost is large.

 

Because of the different laser transmission structure, the fiber laser cutting machine with the same power in the appearance and size is more compact than the CO2 laser cutting machine, thus saving the workshop space. Fiber laser cutting machine maintenance-free, basically no consumables, and can be competent for harsh working environment, dust, shock, impact, humidity, temperature has a high tolerance.

With fiber laser complete solid state digital module, single design, fiber laser cutting machine has higher electro-optical conversion efficiency than carbon dioxide laser cutting. Each power unit of CO2 laser cutting machine, the actual general utilization rate is about 8% to 10%, and fiber laser cutting machine, this value is about 25% to 30%, fiber laser cutting system overall consumption of energy than carbon dioxide cutting system about 3 to 5 times, making the energy efficiency improved to more than 86%.

CO2 laser has complex structure, high maintenance cost, and large beam divergence during processing, so it is not suitable for large-scale processing. Although the cutting seam is relatively thin, it is very slow when machining thick plate. Fiber laser cutting machine laser features in miniaturization, intensification, high brightness and high conversion rate, in thin plate processing, the same power fiber laser cutting machine than CO2 cutting speed 2-3 times higher, cutting section smooth.

 

Fiber laser has the characteristics of short wavelength, which improves the absorption of the cutting material to the beam, and makes it possible to cut such as brass and copper as well as non-conductive materials. The cutting speed of 1.5kW fiber laser cutting machine is equivalent to that of 3kW carbon dioxide laser cutting machine when cutting thick material to 6mm.

CO2 laser cutting machine uses gas as luminescent medium. Due to the purity of CO2 gas, the resonant cavity will be polluted, which needs to be cleaned regularly. The mirror needs to be maintained and calibrated, so the workload of daily maintenance is larger. For a number of kilowatt CO2 laser cutting machine, this will cost at least $20,000 per year. In general, fiber laser cutting is more environmentally friendly and convenient in the daily maintenance of equipment.
