The CO2 CO2 laser cutting machine focuses the CO2 laser beam on the material surface with a focusing mirror to melt the material. At the same time, the compressed gas coaxial with the laser beam is used to blow away the melted material and make the laser beam move relative to the material along a certain trajectory, thus forming a certain shape of slit.
CO2 laser cutting machine has the following advantages:
1. High precision: positioning accuracy is 0.05mm, and repeated positioning accuracy is 0.02mm.
2. Narrow kerf: the laser beam is focused into a small light spot, so that the focal point reaches a high power density. The material is quickly heated to the extent of gasification, and then evaporates to form holes.
3. The cutting surface is smooth: the cutting surface is free of 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 maximum positioning speed can reach 70m/min, which is much faster than the wire cutting speed.
5. Good cutting quality: no contact cutting, little thermal influence on the cutting edge, basically no thermal deformation of the workpiece, completely avoiding the collapse of the edge formed during material punching and shearing, and generally no secondary processing is required for the cutting seam.
6. No damage to the workpiece: the laser cutting head will not contact the material surface to ensure that the workpiece will not be scratched.
7. It is not affected by the hardness of the material to be cut: the laser can process steel plate, stainless steel, aluminum alloy plate, hard alloy, etc. No matter what the hardness, it can perform deformation free cutting.
8. It is not affected by the shape of the workpiece: laser processing is flexible, and can process arbitrary graphics, and can cut pipes and other profiled materials.
9. It can cut and process non-metal materials, such as plastic, wood, PVC, leather, textile and plexiglass.
10. Save mold investment: laser processing does not require mold, no mold consumption, no mold repair, save mold replacement time, thus saving processing costs, reducing production costs, especially suitable for processing large products.
