What are the differences between fiber laser cutting machine and ULTRAVIOLET laser cutting machine?

Laser cutting machine is an important tool in cutting field, known as the fastest "knife". Its principle is through the high density high energy laser beam irradiation material surface, vaporization to remove part of the material, the formation of cutting. According to the characteristics of wavelength, the laser cutting machine is divided into CO2 laser cutting machine, fiber laser cutting machine, green laser cutting machine and ultraviolet laser cutting machine in industrial applications.

Laser cutting processing is to replace the traditional mechanical knife with invisible beam, with high precision, cutting fast, not limited to cutting pattern restrictions, automatic typesetting save materials, smooth incision, low processing costs, will gradually improve or replace the traditional metal cutting process equipment.

So, what are the differences between fiber laser cutting machine and ULTRAVIOLET laser cutting machine?

Fiber laser cutting machine and uv laser cutting machine difference analysis:

1, the difference between processing materials:

Laser application range is very wide, whether fiber laser or ultraviolet laser, can be applied to metal and non-metallic materials, especially ultraviolet laser application range is more extensive, almost covering all fields from metal to non-metal.

According to the characteristics of the processed material, the absorption of the laser band is not the same, so the selection of laser cutting machine is different; According to the quality requirements of processing, the higher the requirements of laser beam quality and thermal influence, the laser cutting machine will be different; According to the thickness of the processing material requirements, the range of laser can do the threshold range is not the same, the selection of laser cutting machine is also different.

In metal material processing, fiber laser cutting machine and ultraviolet laser cutting machine have certain homogeneity, they can process ultra-thin metal materials below 0.2mm, such as copper, nickel, titanium alloy and so on. The difference is that the fiber laser cutting machine processes ultra-thin metal by scanning the galvanometer. The edge will have serious carbonization, and the edge will be deformed because of the heat effect. The edge of different materials even has burrs. Ultraviolet laser cutting machine processing ultra-thin metal efficiency is lower than fiber, but the processing effect is good, no burr edge, low carbonization degree, edge will not be deformed because of heat effect. This difference lies in the processing principle of fiber laser cutting machine and ultraviolet laser cutting machine, fiber laser cutting machine is vaporized cutting, and ultraviolet laser cutting machine is processed by destroying the molecular bond mode of the material, the thermal effect is less.

Fiber laser cutting machine has higher power and greater thermal impact. It is often used for thick metal material cutting, such as stainless steel cutting and carbon steel cutting. The collimation focusing head is used for cutting, and the processing efficiency is high. The power of ultraviolet laser cutting machine can not achieve higher power at the present stage, only for thin non-metallic materials and ultra-thin metal material cutting, such as PCB, FPC, film materials, etc., the galvanometer scanning mode is layer by layer peel cutting.

2, the difference between processing methods:

Fiber laser cutting machine is 1064nm wavelength infrared fiber laser, using collimation and galvanometer processing.

UV laser cutting machine is the use of 355nm wavelength UV UV laser, also can use collimating focusing head and galvanometer scanning processing.

Collimating focusing head is the common way we see laser cutting metal materials that are one-time molding, and galvanometer scanning is like laser marking processing, layer by layer of peeling material to form cutting. It is obvious that the processing method of collimating focusing head is more efficient, but the demand for power is also higher. The power of the common fiber laser cutting machine on the market can do more than 20KW, and the power of the ULTRAVIOLET laser cutting machine can only do hundreds of watts abroad, and the domestic market can only do dozens of watts at present.
