How to distinguish the quality of 4000W fiber laser cutting machine

As a cutting-edge tool, the 4000W fiber laser cutting machine is increasingly being utilized in various industries. This machine, along with other laser technologies such as laser engraving, marking, and welding machines, represents the forefront of precision cutting. The basic principle of laser cutting is to focus the laser energy into a high-density beam. When this beam is directed at the work surface, it generates enough heat to melt the material. This is achieved by combining it with high-pressure gas that removes the molten metal, resulting in the cutting process. This processing method is different from traditional machining machines.

The laser beam emitted from the laser generator is guided through an optical path system and focused to create a high-power density laser beam. When this beam is irradiated on the workpiece, the material absorbs the laser heat, causing a rapid increase in temperature. When the boiling point is reached, the material vaporizes and forms a hole. Accompanied by a high-pressure air flow, the relative movement of the beam and the workpiece results in the formation of the cut seam. The entire process, including parameters such as cutting speed, laser power, and gas pressure, is controlled by a numerical control system to ensure precision. In addition, an auxiliary gas blows off the slugs in the slit.

To measure the quality of laser cutting, several criteria are taken into consideration. Firstly, the roughness of the cut surface (Rz) is important. The smoother the surface, the higher the quality. The size of the slug hanging down into the notch is also an important factor. The minimum slug will result in a clean cut. The verticality and slope (U) of the trimming are also important. An accurately vertical edge reflects good cutting accuracy. In addition, the size of the fillet (R) on the cut edge is evaluated, the smaller the fillet, the finer the cut. The presence of stripe drag (n) and the flatness of the cut material (F) further contribute to the evaluation of the overall cut quality. These criteria collectively determine the performance and effectiveness of the 4000W fiber laser cutting machine in achieving accurate and high-quality cuts.
