Q: What is the difference between optical fiber laser cutting machine and CO2 laser cutting machine?
A: Now, in the metal processing market, the optical fiber laser cutting machine has gradually replaced the CO2 laser cutting machine and the traditional processing means, becoming the mainstream equipment in sheet metal processing. What are the differences and advantages between optical fiber laser cutting machine and CO2 laser cutting machine?
The details are as follows:
1. Different luminous medium
CO2 laser cutting machine, the gas is the medium that generates laser beam, and transmits the beam through the reflector. Optical fiber laser is transmitted through diodes and optical fiber cables. Multiple diodes are pumped to generate laser beams, which are then transmitted to the laser cutting head through flexible optical fiber cables,
Instead of passing the beam through the mirror.
2. Compact appearance of optical fiber laser cutting machine
Due to different laser transmission structures, the optical fiber laser cutting machine with equal power in external dimensions is more compact than the CO2 laser cutting machine, thus saving workshop space.
3. Higher electro-optical conversion power of optical fiber laser cutting machine
With the complete solid state digital module and single planning of fiber laser, the fiber laser cutting machine has higher electro-optical conversion power than CO2 laser cutting. The utilization rate of each power supply unit of CO2 laser cutting machine is generally about 8% to 10% in practice
The value is about 25% to 30%. The overall power consumption of the fiber laser cutting system is about 3 to 5 times less than that of the carbon dioxide cutting system, making the energy efficiency increase to more than 86%.
4. Better processing effect of optical fiber laser cutting machine
Fiber laser has the characteristics of short wavelength, so as to improve the absorption of cutting materials on the beam, and enable cutting such as brass and copper and non-conductive materials. When cutting data up to 6mm thick, the cutting speed of 1.5kW optical fiber laser cutting machine is equivalent to 3kW carbon dioxide laser
Cutting speed of the cutter.
5. Lower protection cost of optical fiber laser cutter
The CO2 laser cutting machine uses gas as the luminous medium. Due to the purity of CO2 gas, the resonant cavity will be polluted, which requires regular cleaning, and the reflector needs protection and calibration. Therefore, the daily protection and maintenance work is more. For a several kilowatt CO2 laser cutting machine
The project requires at least 20000 dollars per year. In conclusion, fiber laser cutting is more environmentally friendly and convenient for daily protection of equipment.
