As one of the core equipment of high-end manufacturing equipment, fiber laser conforms to the environmental background of industrial manufacturing transformation, and meets the requirements of multi-dimensional processing applications with great difficulty and variety. The advantages of fiber laser material processing are very popular in the market, which effectively solves the pain point of high production cost and low production efficiency, and has a huge market space.
Through the application example of laser cutting, the fiber laser cutting equipment, CO2 laser cutting equipment and YAG solid laser cutting equipment are compared and analyzed, and the advantages and development prospects of fiber laser cutting equipment in laser cutting application are discussed.
The advantages of low-cost and high-efficiency fiber laser cutting are prominent.
1、 Operation requirements and maintenance
The 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 maintain the external optical path; YAG solid-state laser thermal mirror has obvious effect and needs frequent maintenance.
Moreover, the fiber laser is transmitted by optical fiber, which is free of adjustment, maintenance, high stability and easier to operate.
2、 Cutting speed and effect
The cutting speed of the fiber laser is 2 ~ 3 times 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 laser cutting machines. The optical fiber laser cutting machine has good beam quality, small cutting gap and flat cutting edge.
3、 Material suitability and application industry
Fiber laser is more in line with the processing requirements of sheet metal manufacturing, 3C home appliances, new energy and other industries.
4、 Energy consumption 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 laser is about 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.
Fiber laser cutting is more precise, the focus can reach 25um, the heat affected zone is small, the cutting seam is small, and the workpiece deformation is small. Dineng laser cutting machine is a flexible processing method. Combined with the automatic control system, the system realizes automatic tracking, automatic edge searching and automatic nesting, greatly improving the production efficiency. It is widely used in metal cutting, with better performance, and can better meet the requirements of fine cutting processing.
