Traditional cutting techniques include flame cutting, plasma cutting, waterjet cutting, wire cutting and punching, etc. Fiber laser cutting machine, as an emerging technique in recent years, is to irradiate a laser beam with high energy density onto the workpiece to be processed. , to melt the part by heating, and then use high-pressure gas to blow off the slag to form a slit. The laser cutting machine has the following advantages.
1. The kerf is narrow, the precision is high, the kerf roughness is good, and there is no need for reprocessing in the subsequent process after cutting.
2. The laser processing system itself is a computer system, which can be easily arranged and modified, and is suitable for personalized processing, especially for some sheet metal parts with complex contours and shapes. The batches are large and the product life cycle is not long. From the perspective of technology, economic cost and time, it is not cost-effective to manufacture molds, and laser cutting is particularly advantageous.
3.Laser processing has high energy density, short action time, small heat-affected zone, small thermal deformation, and small thermal stress. In addition, the laser is non-mechanical contact processing, which has no mechanical stress on the workpiece, and is suitable for precision processing.
4. The high energy density of the laser is enough to melt any metal, especially suitable for processing some materials with high hardness, high brittleness and high melting point that are difficult to process by other techniques.
5. Low processing cost. The one-time investment of equipment is more expensive, but continuous and large-scale processing finally reduces the processing cost of each part.
6. The laser is non-contact processing, with low inertia and fast processing speed. Cooperating with the CAD/CAM software programming of the numerical control system, it is time-saving and convenient, and the overall efficiency is high.
7. The laser has a high degree of automation, can be fully enclosed for processing, has no pollution, and has low noise, which greatly improves the working environment of the operators.
