The principle of laser cutting
Laser cutting uses a focusing lens to focus the laser beam on the surface of the material to melt the material. At the same time, the material is melted by the compressed gas coaxial with the laser beam, and the laser beam and the material are moved relative to each other along a certain path to form a laser beam. A certain shape of slit.
Laser cutting applications
Machine tools, construction machinery, electrical switch manufacturing, elevator manufacturing, food machinery, textile machinery, locomotive manufacturing, agriculture and forestry machinery, food machinery, special vehicles, petroleum machinery manufacturing, aerospace, environmental protection equipment, household appliance manufacturing, large electric machine silicon steel sheets, etc. Machinery manufacturing and processing industry.
The significant advantages of laser cutting
1. High precision: positioning accuracy 0.05mm, repeatable positioning accuracy 0.02 mm
2. Narrow kerf: The laser beam is focused to a very small spot so that the focal point reaches a very high power density. The material is quickly heated to a gasification level and evaporates to form a hole. With the relatively linear movement of the light beam and the material, the holes are continuously formed into narrow slits. The incision width is generally 0.10 to 0.20 mm.
3. Smooth cutting surface: No burr on the cutting surface, the incision surface roughness is generally controlled within Ra12.5.
4. Fast speed: cutting speed up to 10m/min, maximum positioning speed up to 70m/min, much faster than wire cutting.
5. The cutting quality is good: no contact cutting, the heat affected by the cutting edge is very small, there is basically no heat deformation of the workpiece, and the collapsed edge formed when the material is punched and cut is completely avoided, and the secondary slit machining is not generally required.
6. Does not damage the workpiece: The laser cutting head does not come in contact with the surface of the material, ensuring that it does not scratch the workpiece.
7. Not affected by the hardness of the material being cut: The laser can process steel plates, stainless steel, aluminum alloy plates, hard alloys, etc. No matter what kind of hardness, it can be cut without distortion.
8. Not affected by the shape of the workpiece: The laser processing is flexible and can process arbitrary patterns, and can cut pipes and other profiles.
9. Non-metallic cutting can be processed: such as plastics, wood, PVC, leather, textiles, plexiglass and so on.
10. Saving mold investment: Laser processing does not require mold, no mold consumption, no need to repair the mold, saving the time to replace the mold, thus saving processing costs, reducing production costs, especially for large-scale product processing.
11. Save material: Using computer programming, you can use different types of products to complete the entire board material set, maximize the utilization of the material.
12. Improve the speed of new product development: After the product drawing is formed, laser processing can be carried out immediately to get the new product in the shortest time.
