Laser cutting in china is the laser beam emitted from a laser that is focused into a high power density laser beam via an optical path system. The laser beam is irradiated onto the surface of the workpiece to bring the workpiece to a melting point or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the beam moves relative to the workpiece, the material is finally slit, thereby achieving the purpose of cutting. 02:31 Laser cutting in china has many advantages: 1. High precision: positioning accuracy 0.05mm, repeat positioning accuracy 0.02mm. 2. Narrow slit: The laser beam is focused into a small spot, so that the focal point reaches a very high power density. The material is heated to a degree of vaporization and evaporates to form a hole. As the beam moves relatively linearly with the material, the holes are continuously formed into slits of narrow width. The width of the slit is generally 0.10-0.20 ram.

The cutting surface is smooth: the cutting surface has no burrs, and the surface roughness of the cutting surface is generally controlled in Ral2.5; A. 4. Fast speed: cutting speed can reach 10m/min, and the maximum positioning speed can reach 70m/m/n, which is much faster than wire cutting. 5. Good cutting quality: no contact cutting, the edge is less affected by heat, there is basically no thermal deformation of the workpiece, completely avoiding the collapse formed when the material is punched and sheared, and the slit generally does not require secondary processing. 6. Does not damage the workpiece: the laser cutting head will not contact the surface of the material to ensure that the workpiece is not scratched. 7. Not affected by the shape of the workpiece: laser processing is flexible, can process any graphics, and can cut pipes and other profiles. 8. Saving mold investment: laser processing does not require mold, no mold consumption, no need to repair the mold, saving time to replace the mold, thereby saving processing costs and reducing production costs, especially suitable for processing large products. 9. Material saving: Computer programming can be used to cut the entire board material in different shapes to maximize the utilization of materials. 10. Shorten the manufacturing cycle of new products: new products are trial-produced, the quantity is small, the structure is uncertain, and it will be changed at any time. The mold can not be produced at all. The laser cutting machine greatly shortens the manufacturing cycle of new products and reduces the investment of molds. Laser cutting technology in china can not only cut metal materials such as steel plates, stainless steel, aluminum alloy plates, hard alloys, but also non-metallic materials such as plastics, wood, PVC, leather, textiles and plexiglass.
