Nowadays, the wide application of laser cutting technology has made the laser cutting machine really “hot”. Basically, in many processing factories, we can see the laser cutting machine, which has good processing performance for both organic and inorganic materials. Especially in the metal processing industry, many metal materials, regardless of their hardness, can be cut without deformation. Of course, for high-reflectivity materials, such as gold, silver, copper and aluminum alloys, they are also good heat transfer conductors, so laser cutting is very difficult, or even impossible.
For the traditional plasma cutting machine, laser cutting without burr, wrinkle and high precision is superior to plasma cutting. For many mechanical and electrical manufacturing industries, because the modern laser cutting system controlled by computer program can easily cut workpieces of different shapes and sizes, it is often preferred over punching and molding processes. Although its processing speed is still slower than that of die punching, it has no mold consumption, no need to repair the mold, and it also saves time to replace the mold, thus saving processing costs and reducing production costs, so it is more cost-effective in general.
Secondly, from the perspective of how to adapt the mold to the design size and shape changes of the workpiece, laser cutting can also play its advantages of accuracy and reproducibility. As the preferred manufacturing method of laminated mold, the laser cutting operation cost is not expensive because it does not require senior mold makers, so it can significantly reduce the mold manufacturing cost. The additional benefit of laser cutting mold is that the mold trimming will produce a shallow hardening layer (heat affected zone) to improve the wear resistance of the mold during operation.
Analysis of advantages of laser cutting
1. The laser beam of the laser cutting machine is focused to form a very small action point with extremely strong energy, and its heat energy is kept in a very small area, so the cutting seam is small, the heat affected area of the adjacent trimming is small, and there is no other local deformation.
2. The workpiece processed by the laser cutting machine does not have any applied force and does not need to be cut in contact, so the workpiece processed has no mechanical deformation, and there is no tool wear during cutting, and there is no tool conversion problem. It is not necessary to consider the hardness of the workpiece, that is, the laser cutting ability is not affected by the hardness of the material to be cut, and any hardness material can be cut.
3. The laser beam of the laser cutting machine has strong controllability, high adaptability and flexibility, so it is convenient to combine with the automation equipment and easy to realize the automation of the cutting process. Because there is no restriction on the cutting workpiece, the laser beam has unlimited profiling cutting ability, and it can be combined with the computer to layout the whole sheet and save materials.
Therefore, the fact that the laser cutting process is so “hot” is justified. However, selecting a suitable laser cutting opportunity can make things more efficient with less effort.
