Abstract
The laser cutting machine is an important tool in the cutting field and is known as the fastest “knife”. The principle is to shine a high-energy, high-density laser beam on the material surface.
This vaporizes and removes part of the material to form a cut. According to wavelength, industrial laser cutting machines include CO2, fiber, green, and ultraviolet types.
Laser cutting processing is to replace the traditional mechanical knife with an invisible beam. It offers high precision and fast cutting. It is not limited to cutting patterns. It supports automatic typesetting and saves materials. It delivers smooth cuts and low processing costs.
It will be gradually improved or replaced. Traditional metal cutting process equipment.
Different between fiber laser cutter and UV laser cutter
So, what are the differences between fiber laser cutting machine and ultraviolet laser cutting machine?
Analysis of the difference between fiber laser cutting machine and ultraviolet laser cutting machine:
1. The difference of processing materials:
The application range of laser is very wide. Whether you use a fiber laser or an ultraviolet laser, you can apply it to metal and non-metal materials. In particular, ultraviolet lasers have a wider range of uses. They cover almost all fields, from metal to non-metal.
According to the material being processed, laser absorption varies by waveband.
So, the selected laser cutting machine may differ.
According to the required cutting quality, the choice may also differ.
Higher requirements need better beam quality and less thermal impact.
According to the material thickness, the laser’s achievable range also changes.
So, the selected laser cutting machine may differ again.
In the processing of metal materials, the fiber laser cutting machine and the ultraviolet laser cutting machine have a certain degree of homogeneity, and both can process ultra-thin metal materials below 0.2mm, such as copper, nickel, and titanium alloys. The difference is that the fiber laser cutting machine uses galvanometer scanning to cut ultra-thin metal.
The edges may become severely carbonized. Heat may also deform the edges. Different materials may even produce burrs on the edges.
The efficiency of ultra-thin metal processing by an ultraviolet laser cutting machine is lower than with optical fiber. However, the processing effect is good. The edge is free of burrs. The level of carbonization is low. The edge will not deform due to heat.
This difference lies in the processing principle of the fiber laser cutting machine and the ultraviolet laser cutting machine. The fiber laser cutting machine is vaporized cutting, and the ultraviolet laser cutting machine is processed by breaking the molecular bond mode of the material, and the thermal effect is smaller.
Fiber laser cutting machine has higher power and greater thermal influence. It is often used for cutting thicker metal materials, such as stainless steel cutting, carbon steel cutting, etc. It uses collimated focusing head cutting, which has high processing efficiency.
The power of the UV laser cutting machine cannot achieve higher power at this stage. It can only be used for the cutting of thin non-metallic materials and ultra-thin metal materials.
2. The difference in processing methods:
The fiber laser cutting machine uses an infrared fiber laser with a 1064 nm wavelength.
The beam is processed by collimation and a galvanometer.
The ultraviolet laser cutting machine uses a 355nm wavelength UV ultraviolet laser, and it can also use collimated focusing head and galvanometer scanning processing methods.
The common collimating focusing head is the one-time forming method of laser cutting metal materials that we have seen, and the scanning of the galvanometer is like the processing method of laser marking, and the material is peeled off layer by layer to form a cut.
Obviously, the efficiency of the collimating focusing head processing method is higher, but the power requirements are also higher. The power of most common fiber laser cutting machines on the market can exceed 20 kW.
Ultraviolet laser cutting machines abroad are often only a few hundred watts.
In the current domestic market, they are often only tens of watts.
