The working principle of laser cutting machine is to use the focused high power density laser beam to irradiate the workpiece, so that the irradiated material can melt, vaporize, ablate or reach the ignition point rapidly. At the same time, the molten material can be blown out by the high-speed airflow coaxial with the beam, so that the workpiece can be cut off. Laser cutting is one of the hot cutting methods. Compared with other thermal cutting methods, the advantages of laser cutting can be summarized as follows: good cutting quality: due to the small laser spot, high energy density and fast cutting speed, laser cutting can obtain better cutting quality.
① The laser cutting cuts are thin and narrow, both sides of the cutting seam are parallel and perpendicular to the surface, and the dimension accuracy of the cutting parts can reach ± 0.02mm.
② The cutting surface is clean and beautiful, and the surface roughness is only tens of microns. Even laser cutting can be used as the last process, without machining, and parts can be used directly.
③ After laser cutting, the width of the heat affected zone is very small, and the performance of the material near the cutting seam is almost unaffected. Moreover, the deformation of the workpiece is small, the cutting accuracy is high, the geometry of the cutting seam is good, and the cross section of the cutting seam presents a regular rectangle.
Advantages of 3mm fiber laser cutting machine: 1. High cutting accuracy: positioning accuracy of laser cutting machine is ± 0.02mm, repetitive positioning accuracy is ± 0.02mm. 2. The cutting surface of laser cutting machine is smooth: there is no burr on the cutting surface, and the roughness of the cutting surface is generally controlled within ra6.5. 3. The speed of laser cutting machine is fast: the cutting speed can reach 10m / min, the maximum positioning speed can reach 30m / min, which is much faster than that of wire cutting. 4. Laser cutting machine has good cutting quality: non-contact cutting, little thermal impact on the cutting edge, basically no thermal deformation of the workpiece, which can avoid the edge collapse caused by material punching and cutting, and generally no secondary processing is required for cutting seam. 5. No damage to the workpiece: the laser cutting head will not contact with the material surface, to ensure that the workpiece is not scratched. 6. Not affected by the shape of the workpiece: laser processing flexible, can process any graphics, can cut pipes and other profiles. 7. Laser cutting machine can cut many kinds of materials, such as stainless steel, carbon steel, aluminum plate and so on. 8. Saving mold investment: laser processing does not need mold, no mold consumption, no need to repair mold, saving time to replace mold, thus saving processing costs, reducing production costs, especially suitable for large product processing. And one-time molding! 9, saving materials: using computer programming, you can cut different shapes of products, maximize the utilization of materials. 10. Improve the sample delivery speed: after the product drawing is formed, the laser processing can be carried out immediately, and the new product can be obtained in the shortest time. 11. Safety and environmental protection: laser processing waste less, low noise, clean, safe, pollution-free, greatly improved the working environment.
