Fiber laser cutting machine is a mechanical CNC laser cutting machine. It uses a fiber laser source to output a high-energy-density laser beam to instantly melt and vaporize the ultra-fine focus area on the workpiece, and move it through the CNC mechanical system for point irradiation. , So as to achieve cutting.
Fiber laser cutting machines are widely used to cut metal materials, such as steel, carbon steel, stainless steel, copper, aluminum, iron and various alloys, whether it is sheet, tube or pipe. It is divided into several types according to function and appearance. For example, fiber laser machines for cutting plates, tubes, and fiber laser machines with exchange platforms, protective covers, high precision, etc.
- High cutting accuracy: the positioning accuracy of the metal laser cutting machine can reach 0.05mm, and the repeated positioning accuracy can reach 0.03mm.
- Slit: The width of the slit is generally 0.10-0.20mm.
- Smooth cutting surface: There is no burr on the cutting surface, and the roughness of the cutting surface is generally controlled within Ra6.5.
- Fast cutting speed: The cutting speed can reach 10m/min, and the maximum positioning speed can reach 30m/min.
- Good cutting quality: non-contact cutting is adopted, the knife edge is less affected by heat, and the workpiece is basically free of thermal deformation to ensure that the workpiece is not scratched. Generally, the slitting does not require secondary processing.
- Good flexibility in laser processing: The fiber laser cutting machine can process any graphics, and can cut pipes and other profiles without being affected by the shape of the workpiece.

Yes, its Auxiliary air used in fiber laser cutter machine.
The auxiliary gas can be reactive or non-reactive. If the gas is reactive, it can change the properties of the metal it cuts in the incision. At the edge of the part, it will react with the metal components during the cutting process, and cause the metal to oxidize, causing the metal to rust in a short time.
When edge quality is not important, a reactive gas can be used. For example, when the low carbon steel material continues to another step of the process within 24 hours. Non-reactive auxiliary gas can be used for cutting workpieces where edge quality is important. (For example: if the next process is laser welding)
We will focus on 4 auxiliary gases: compressed air, nitrogen, oxygen and argon.
Compressed air is the simplest auxiliary gas option and can be connected to existing workshop air installations. Most shop compressors operate between 75-175 psi, so depending on the application, a booster may be required. For example, for a laser cutting machine, 1.5 mm/0.060 inch/16 ga mild steel may cut best in the range of 150-200 psi. Before entering the cutting head, the air needs to be cleaned to remove oil or moisture and prevent contamination of the optical components, so a filter is needed to ensure clean air for fiber laser cutter.
As an auxiliary gas for laser cutter, compressed air widely used in metal laser cutter. It is a mixture of other gases (including nitrogen and oxygen). Due to its oxygen content, compressed air is considered a reactive cutting gas for metal processing. However, its reactivity is not as good as oxygen assist gas. Compressed air can cut aluminum with high quality, and the speed is slightly higher than when cutting nitrogen or oxygen in a thinner material thickness. Depending on the application requirements, compressed air can be used with many other metals.
In most cases, nitrogen is considered to be the best edge quality for auxiliary gas generation. For most purposes, except for some special materials (such as titanium), nitrogen is considered a non-reactive or inert auxiliary gas in fiber laser cutter use. This means that during the cutting process, nitrogen does not react with any component of the metal. This means that there is no major chemical difference at the fiber cutting edge, and the mechanism of material removal is simply the pressure of the gas jet pushing the molten metal out of the cut. Since this is a relatively cold process, nitrogen-assisted gas cutting can provide very high-quality cutting edges for a variety of materials with very thin heat-affected zones. Nitrogen is most suitable for cutting aluminum, mild steel, galvanized steel, and UHSS automotive steel.
This auxiliary gas is usually used for parts that need to be stored for a period of time before use, because oxygen and air cutting will introduce oxides around the cutting edge during long-term storage.
Oxygen is one of the first auxiliary gases used because it is reactive when fiber laser machine cutting. When processing steel, oxygen will burn off the carbon in the steel during in the cut process. The incision generates additional heat, allowing lower-power lasers to cut thicker materials. Although, this same reactivity will also have some negative effects for laser cutter result. If good edge quality is required, the material is usually limited by speed and air pressure. Compared with nitrogen cutting, the flow rate and pressure of oxygen cutting are often lower. This leads to lower gas consumption and lower operating costs. However, in some cases, the fiber laser cutting speed will be slightly slower.
Argon is the rarest and most expensive gas encountered by most processors. Materials that are well cut with nitrogen can also use argon with similar high-quality edges. The main reason for using the more expensive argon is to cut metals that are still chemically reactive in pure nitrogen. Most commonly, argon is used to process titanium. At the temperature that the laser cutter raises the metal to, titanium is chemically reactive even in a pure nitrogen atmosphere. This is the main reason for choosing argon instead of nitrogen in the fiber laser cutting. Although argon is inert and the cutting method is similar to nitrogen, there are two differences that may limit wider use. Argon has a higher specific heat than the other auxiliary gases in this list. This means that although nitrogen is said to cool the cutting while cut material, and oxygen is said to add heat to the cutting, argon removes heat from the cutting even faster than nitrogen.
In the fiber laser cutting machines, CO2 laser cutting machine is possible to cut glass better.

Because we are able to cut according to different ways, when we understand some of the most suitable cutting methods for reference.

Let us save trouble and effort in the cutting process. Meet our market needs and help each of us get the most exquisite gifts.
- Stainless steel：10mm
- Carbon steel：20mm
Fiber laser beam can provide metal-friendly wavelength, metal absorption is more effective, smaller spot size (1 micron wavelength) and excellent beam profile make it ideal for cutting most metals. Most notably, compared with the CO 2 hybrid laser machine, when cutting thin metal sheets with a thickness of 3 mm or less, its linear speed is 2-3 times faster.
In terms of operating cost, compared with CO 2, optical fiber only needs about 1/3 of the operating power. In addition, fiber optics provide shorter downtime and less continuous maintenance can increase productivity.
Therefore, in most metal cutting applications, optical fibers have rapidly replaced traditional CO 2 lasers.
