What is the laser for cutting metal? let me tell you

There are many kinds of industrial laser light sources, besides optical fiber, ultraviolet, green light, CO2 and so on. If you ask someone about a laser for cutting metal, it will generally be understood as a fiber laser. For metal cutting, optical fiber is the easiest to be absorbed. Cutting metal has better quality and faster speed.
Optical fiber is used as a laser for cutting metal, and its equipment is called a fiber laser cutting machine. The fiber laser cutting machine outputs high-energy-density laser beams and gathers them on the surface of the workpiece to instantly melt and vaporize the area irradiated by the ultra-fine focus spot on the workpiece. Automatic cutting is realized by moving the spot irradiation position through the CNC mechanical system.
The reason why fiber laser cutting machine is a laser for cutting metal belongs to the processing category of metal laser cutting machine, so it can only cut metal, not non-metal such as cloth, leather, stone, etc. The reason is very simple. The wavelength range of fiber laser cutting machine is not The above materials are within the absorption range, or the absorption is not appropriate, and the ideal cutting effect cannot be achieved. At present, the advantages of applying non-metallic cutting are not very obvious.
CO2 lasers and UV lasers can also be used as lasers for cutting metals, but the absorption of these two light sources by metals is not good enough, the cutting speed is slow, the cutting accuracy is not high, and the cost will be higher, so it is not suitable for industrial use. used.
