The main advantages of laser cutting technology in automobile manufacturing The laser cutting machine has been widely used in the automobile manufacturing industry and plays an irreplaceable role with other CNC cutting equipment. Its main advantages are as follows:
1. Applicable to a variety of material accessories
Automobile materials include low-carbon low-alloy steel, high-strength steel, atmospheric corrosion-resistant steel, ferritic stainless steel, austenitic stainless steel and aluminum alloy, etc. Laser cutting equipment can be processed, and its processing range can cover almost all materials in the car. Pieces.
2. High machining accuracy
Laser cutting equipment has higher processing accuracy than other cutting equipment and can meet the processing requirements of high-precision parts.
3. Narrow slit width
The small slit is beneficial to reduce the spacing of accessories, improve material utilization, and produce less cutting slag during cutting.
4. High material utilization
When cutting parts, it can cut different parts of the same thickness and material, making full use of the leftover material of the raw materials.
5. Low cutting roughness value
Laser cutting equipment, when cutting parts of the same material, compared to other equipment, the cutting roughness value is lower. In the automobile manufacturing industry, there are obvious differences in the section roughness of workpieces processed by different CNC cutting equipment, and the laser cutting section roughness value is low.
6. Small heat affected zone
During the laser cutting process, the edge of the material being cut will produce a heat-affected zone due to heat. However, laser cutting has lower energy concentration and heat input than other processing methods. Compared with fine plasma cutting and flame cutting, the heat affected zone is relatively small, and the heat input is small. The hard tendency of high-strength steel is of great significance and is beneficial to improving the quality of the weld.
7. Low cost of laser cutting for small batch production
In mass production, the process of mold blanking is selected for processing, mass production, the cost of making molds is equally spread to each part, and the production cost is lower. However, if it is small batch production and the processing technology of die punching is adopted, not only the production cycle of the die is longer, and the timeliness of parts processing cannot be satisfied, but the mold production cost is evenly distributed to each part, and the processing cost is relatively high.
Therefore, CNC cutting is generally used for processing. When using CNC fine plasma cutting, because the piercing ability of plasma cutting is weak, the cutting precision is low, and the quality of the hole formation is poor, an additional drilling process is needed, and a drilling mold needs to be made. Not only the processing time is longer, but the cost is also relatively high. Laser cutting can ensure that parts are formed at one time, which is beneficial to improve the timeliness of parts processing, and is suitable for small batch production. How to choose the cutting process requires comprehensive consideration based on the size, shape, cost and accuracy of the accessories. When the size of the accessories is small, and the requirements for the shape and size of the hole and the positioning size are high, the laser cutting method is more economical.
