What are the main benefits of fiber laser cutting machines?

All laser cutting processes have their inherent advantages and disadvantages, but it seems that the advantages of fiber laser cutting machines far outweigh any other process. Fiber laser has only begun to gain traction in the past few decades or so, but the benefits it has brought have been quickly realized by metal manufacturers across the country. Fiber laser cutting machines can easily and seamlessly adapt to a wide range of applications between industries.

What are the benefits of a fiber laser cutting machine? 

Fiber lasers offer several key advantages: the light propagating in the fiber is well shielded from environmental interference, fiber lasers tend to be very compact in design, they have a large gain bandwidth, a wide wavelength tuning range, and the ability to produce ultrashort pulses. They operate efficiently at high power and are suitable for many types of cutting procedures. Fiber lasers can cut through thin materials at very high speeds. They also have the ability to cut reflective materials without the risk of reflections damaging the machine, allowing them to cut metals such as copper, brass, and aluminum.

No Heat Damage to Objects

The lasers emitted by fiber laser cutting machines are extremely powerful, which is why it can easily cut thicker materials such as steel. And they are so precise that the beam does not cause any damage to surrounding materials. Many industries can benefit from this. Think about the electronics industry, where the beam needs to work at very small sizes without damaging any components necessary to make these electronic devices work properly. 

Superior Performance

You will also find that fiber lasers offer higher performance than many of their counterparts. Fiber lasers offer a higher level of beam quality, can be highly focused for extremely precise levels of accuracy, and increase power density. This also means that tasks can be completed at faster speeds and with less power consumption. The main reason for fiber laser cutting technology is to reduce the mechanical stress that sheet metal is subjected to when cutting. The laser helps to eliminate impact stresses that can adversely affect sheet metal products during the cutting process. In addition, the heat-affected zone is very small, which means that the rest of the workpiece is hardly exposed to heat, thus preserving the characteristics of the material being processed, which is very important. Also, since laser cutting does not negatively affect sheet metal, it helps to minimize waste - tight cuts allow more parts to be made per square foot of sheet metal.So what advantages does it have when processing materials?You can check the following details：

Cutting advantages

1. High cutting accuracy: The positioning accuracy of the laser cutting machine is 0.05mm, and the repeat positioning accuracy is 0.03 mm.

2. The laser cutting machine has a narrow slit: The laser beam is focused into a very small light spot, so that the focus reaches a very high power density, and the material is quickly heated to the degree of gasification, evaporating to form holes. As the beam and the material move linearly relative to each other, the holes continuously form a very narrow slit, and the slit width is generally 0.10-0.20mm.

3. The cutting surface of the laser cutting machine is smooth: there are no burrs on the cutting surface, and the surface roughness of the cut is generally controlled within Ra6.5.

4. The laser cutting machine is fast: the cutting speed can reach 10m/min and the maximum positioning speed can reach 30m/min, which is much faster than the speed of wire cutting.

5. The cutting quality of the laser cutting machine is good: non-contact cutting, the cutting edge is little affected by heat, there is basically no thermal deformation of the workpiece, and the collapse of the edge formed during the punching and shearing of the material is completely avoided. The slit generally does not require secondary processing.

6. No damage to the workpiece: The laser cutting head will not contact the surface of the material to ensure that the workpiece will not be scratched.

7. Not affected by the shape of the workpiece: Laser processing is flexible and can process any graphics, and can cut pipes and other special-shaped materials.

8. The laser cutting machine can cut and process a variety of materials: such as plastic, wood, PVC leather, textiles, plexiglass, etc.

9. Save mold investment: Laser processing does not require molds, no mold consumption, no need to repair molds, save mold replacement time, thereby saving processing costs and reducing production costs, especially suitable for the processing of large products.

10. Save materials: Using computer programming, products of different shapes can be cut to maximize the utilization of materials.

11. Increase the speed of sample delivery: After the product drawing is formed, laser processing can be carried out immediately, and the physical object of the new product can be obtained in the shortest time.

12. Safety and environmental protection: Laser processing has less waste, low noise, clean, safe, and pollution-free, which greatly improves the working environment.
