As one of the core components of high-end manufacturing equipment, fiber laser is in line with the background of industrial manufacturing transformation, and is capable of handling multi-dimensional processing application requirements with high difficulty and large changes. The advantages of fiber laser material processing make it highly favored in the market, efficiently solving pain points such as high production costs and low production efficiency, thus there is a huge market space.

Taking laser cutting applications as an example, this paper compares the processing characteristics of fiber laser cutting machines, CO2 laser cutting machines, and YAG solid laser cutting machines, and explores the advantages and development potential of fiber laser in laser cutting applications.

The advantages of low-cost and high-efficiency fiber laser cutting are highlighted

(1) Operation requirements and maintenance

CO2 laser requires optical path adjustment, and the effect of optical path adjustment will affect cutting quality. Therefore, operators need to have skill requirements and maintain the external optical path; The thermal lens effect of YAG solid-state laser is obvious and requires regular maintenance.

Fiber laser fiber transmission is adjustable, maintenance free, highly stable, and easier to operate.

(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 a significant advantage in the three types of laser cutting machines. The fiber laser cutting machine has good beam quality, smaller cutting gaps, and smoother cutting edges.

(3) Material Applicability 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 level and comprehensive cost

The photoelectric conversion rate of fiber laser is over 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 3%. The power consumption of fiber laser is only 20-30% of that of CO2 laser with the same power, and the overall cost is lower.

Fiber laser cutting is more precise, with a focus of up to 25um, a small heat affected zone, small cutting seams, and minimal workpiece deformation. As a flexible processing method, the Dineng laser cutting machine can be combined with an automation control system to achieve automatic tracking, automatic edge finding, and automatic nesting, greatly improving production efficiency. It is widely used in metal cutting and performs better, meeting the requirements of fine cutting processing.
