What are the advantages of fiber lasers in cutting applications1
As one of the core components of high-end manufacturing equipment, fiber lasers are in line with the background of industrial manufacturing transformation and meet the requirements of difficult and changing multi-dimensional processing applications. The advantages of fiber laser material processing make it popular in the market, and it efficiently solves the pain points of high production cost and low production efficiency, so there is a huge market space.
Take the laser cutting application as an example, compare the processing characteristics of fiber laser cutting machine, CO2 laser cutting machine, and YAG solid laser cutting machine, and explore the application of fiber laser in laser cutting Advantages and development potential.
The advantages of low-cost and high-efficiency fiber laser cutting are highlighted
(1) Operational requirements and maintenance
The CO2 laser needs to be adjusted in the optical path, and the effect of the optical path adjustment will be Affect the cutting quality, so the operator needs to have certain skill requirements, and need to maintain the external optical path; the YAG solid-state laser has obvious thermal lens effect and requires frequent maintenance.
The fiber laser fiber transmission is free of adjustment, maintenance, high stability, and easier to operate.
(2) Cutting speed and effect
The cutting speed of fiber laser is 2-3 times that of CO2 laser of the same power, especially in the cutting of thin metal plate. The cutting speed has obvious advantages in the three types of laser cutting machines. Fiber laser cutting machine has better beam quality, smaller cutting gap, and smoother cutting edge.
(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 and overall cost
Optical conversion rate of fiber laser is more than 30%, the photoelectric conversion rate of the same power CO2 laser cutting machine is about 10-15%, solid laser The photoelectric conversion rate is 3%. The power consumption of fiber laser is only 20-30% of the same power CO2 laser, and the overall cost is lower.
Fiber laser cutting is more precise, the focal point can reach 25um, the heat affected zone is small, the slit is small, and the deformation of the workpiece is small. As a flexible processing method, Dineng laser cutting machine can be combined with an automatic control system to realize automatic tracking, automatic edge finding, and automatic nesting, which greatly improves production efficiency. It is widely used in metal cutting, has better performance, and can be better. Meet the requirements of fine cutting processing.
