At the same time, it also has the advantages of fine kerf, small heat-affected zone, good cutting surface quality, no noise during cutting, good verticality of kerf edge, smooth cutting edge, and easy automatic control of the cutting process. It can cut carbon steel, stainless steel, alloy steel, wood, plastic, rubber, cloth, quartz, ceramic, glass, composite materials, etc. When laser cutting plates, no molds are required, and it can replace some punching processing methods that require complex and large molds, which can greatly shorten the production cycle and reduce costs. Therefore, laser cutting has been widely used in industrial sectors such as automobiles, rolling stock manufacturing, aviation, chemical industry, light industry, electrical appliances and electronics, petroleum and metallurgy. The significant advantages of laser cutting are:
1. High precision: the positioning accuracy is 0.05mm, and the repeat positioning accuracy is 0.02 mm.
2. Narrow slit: the laser beam is focused into a small light spot, so that the focal point reaches a high power density, and the material is quickly heated to the degree of gasification, and evaporates to form holes. As the beam moves linearly relative to the material, the holes are continuously formed into narrow slits. The incision width is generally 0.10-0.20mm.
3. The cutting surface is smooth: the cutting surface has no burrs, and the surface roughness of the incision is generally controlled within Ra12.5.
4. Fast speed: the cutting speed can reach 10m/min, and the positioning speed can reach 70m/min, which is much faster than wire cutting.
5. Good cutting quality: non-contact cutting, the cutting edge is less affected by heat, basically no thermal deformation of the workpiece, completely preventing the collapse of the edge formed during the punching and shearing of the material, and the cutting seam generally does not require secondary processing.
6. No damage to the workpiece: the laser cutting head will not touch the surface of the material, so as not to scratch the workpiece.
7. Not affected by the hardness of the material to be cut: the laser can process steel plates, stainless steel, aluminum alloy plates, hard alloys, etc., no matter what the hardness is, it can be cut without deformation.
8. Not affected by the shape of the workpiece: laser processing has good flexibility, can process any graphics, and can cut pipes and other special-shaped materials.
9. It can cut and process non-metal: such as plastic, wood, PVC, leather, textiles, plexiglass, etc.
10. Saving mold investment: laser processing does not require molds, no mold consumption, no need to repair molds, saves time for mold replacement, thereby saving processing costs and reducing production costs, especially suitable for processing large-scale products.
11. Material saving: Using computer programming, products of different shapes can be cut into the whole board material to maximize the utilization rate of materials.
12. Improve the speed of new product development: After the product drawing is formed, laser processing can be carried out immediately, and the new product can be obtained in the shortest time.
