The laser cutting machine has a narrow slit, small deformation of the workpiece, and the laser beam is focused into a small light spot, which makes the focal point reach a high power density. At this time, the heat input by the light beam far exceeds the part of the material that is reflected, transmitted or diffused, and the material is quickly heated to the degree of vaporization, and the holes are formed by evaporation. With the relatively linear movement of the light beam and the material, the hole continuously forms a narrow slit. The cutting edge is affected by heat little, and there is almost no deformation of the workpiece.
Most organic and inorganic materials can be laser cut . In the non-metal processing industry where industrial processing systems take a large part, many non-metal materials, regardless of their hardness, can be cut without deformation. Of course, for materials with high reflectivity, such as plexiglass, crystal, acrylic, etc., it is not difficult to cut with a laser cutter .
The laser cutting machine has no burrs, wrinkles, and high precision, which is superior to plasma cutting. For many electromechanical manufacturing industries, since modern laser cutting machines controlled by microcomputer programs can easily cut workpieces of different shapes and sizes, it is often preferred over die cutting and stamping processes; although its processing speed is slower than die stamping, but It has no mold consumption, no need to repair the mold, and saves mold replacement time, which saves processing costs and reduces production costs, so it is more cost-effective in general.
On the other hand, from the perspective of how to adapt the mold to the size and shape of the workpiece design, the laser cutting machine can also take advantage of its accuracy and good reproducibility. As a priority manufacturing method for laminated molds, since advanced mold making is not required, and the operating cost of the laser cutting machine is not expensive, it can also significantly reduce the mold manufacturing costs.
