As one of the core components of high-end manufacturing equipment, fiber laser machine meets the environmental background of industrial manufacturing transformation and is competent for the application requirements of multi-dimensional processing with high difficulty and great changes. The advantages of fiber laser material processing make it popular in the market, and effectively solve the pain points of high production cost and low production efficiency. Therefore, there is a huge market space.
Taking the application of laser cutting as an example, the processing characteristics of fiber laser cutting machine, CO2 laser cutting machine and YAG solid-state laser cutting machine are compared, and the advantages and development potential of fiber laser in laser cutting application are explored.
Low cost and high efficiency fiber laser cutting advantages highlight
(1) Operation requirements and maintenance
CO2 laser needs to adjust the optical path, and the effect of optical path adjustment will affect the cutting quality, so the operator needs to have certain skill requirements and need to maintain the external optical path; YAG solid-state laser has obvious thermal lens effect and needs frequent maintenance.
And fiber laser fiber transmission, free of adjustment, maintenance, high stability, easier operation.

(2) Cutting speed and effect
The cutting speed of fiber laser is 2-3 times that of CO2 laser with the same power, especially in metal sheet cutting. The cutting speed of fiber laser cutting machine has obvious advantages in three types of laser cutting machines. Optical fiber laser cutting machine has better beam quality, smaller cutting gap and smoother cutting edge.
(3) Material applicability and application industry
Fiber lasers are more in line with the processing requirements of sheet metal manufacturing, 3C home appliance industry and new energy industry.
(4) Energy consumption degree and comprehensive cost
The photoelectric conversion rate of fiber laser is more than 30%, the photoelectric conversion rate of CO2 laser cutting machine with the same power is about 10-15%, and the photoelectric conversion rate of solid-state laser is 3%. The power consumption of fiber lasers is only 20-30% of that of CO2 lasers with the same power, and the comprehensive cost is lower.
