As one of the core components of manufacturing equipment, the optical fiber laser machine fits the background of industrial manufacturing transformation and is competent for multi-dimensional processing and application requirements with high difficulty and great changes. The advantages of fiber laser material processing make it popular in the market, solving the pain points of high production cost and low production efficiency, so there is a huge market space.
Taking laser cutting application as an example, the processing characteristics of fiber laser cutting machine, CO2 laser cutting machine and YAG solid laser cutting machine are compared to explore the advantages and development potential of fiber laser in laser cutting application.
Low cost and high efficiency advantages of fiber laser cutting
(1) Operation requirements and maintenance
The CO2 laser needs to adjust the optical path, and the effect of the optical path adjustment will affect the cutting quality, so the operators need to have certain skill requirements and need to maintain the external optical path; YAG solid state laser has obvious thermal lens effect, which requires frequent maintenance.
And fiber laser fiber transmission, no adjustment, no maintenance, high stability, easy operation.

(2) Cutting speed and effect
The cutting speed of the fiber laser is 2-3 times that of the CO2 laser with the same power. Especially in the metal sheet cutting, the cutting speed of the fiber laser cutting machine has obvious advantages among the three types of laser cutting machines. The optical fiber laser cutter has better beam quality, smaller cutting gap and smoother cutting edge.
(3) Material suitability and application industry
Fiber laser is 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 cutter with the same power is about 10-15%, and the photoelectric conversion rate of solid laser is 3%. The power consumption of fiber laser is only 20-30% of that of CO2 laser with the same power, and the comprehensive cost is lower.
