In order to meet the needs of export and domestic upgrading in the automobile manufacturing industry, mass production and high-quality production have become an inevitable trend. The original processing technology of automobile body parts can no longer fully meet today's product quality and production needs. Laser cutting machines have The characteristics of accessories with high precision and complex shapes are irreplaceable.

Now truck manufacturers have been equipped with laser cutting machines, which are used for the processing of sheet metal parts with complex shapes and high precision requirements in automobiles. The main advantages of laser cutting machines have been widely used in the automobile manufacturing industry, and play an irreplaceable role in other CNC cutting equipment. Its main advantages are as follows:
1. Applicable to a variety of material accessories
Automotive materials include low-carbon and low-alloy steel, high-strength steel, atmospheric corrosion-resistant steel, ferritic stainless steel, austenitic stainless steel and aluminum alloy, etc. All laser cutting equipment can process it, 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 accessories.
3. Narrow slit width
Small slits are beneficial to reduce the spacing of accessories, improve material utilization, and produce less cutting slag during cutting.

4. High utilization rate of materials
When cutting accessories, you can cut different accessories of the same thickness and material, making full use of the leftovers of the raw materials.
5. Low cut roughness value
Laser cutting equipment, when cutting accessories of the same material, has a lower cutting roughness value than other equipment. In the automobile manufacturing industry, the cross-section roughness of workpieces processed by different CNC cutting equipment is significantly different, and the cross-section roughness value of laser cutting is low.
6. Small heat affected zone
During the laser cutting process, the edge of the material to be cut will generate a heat-affected zone due to heat. However, compared with other processing methods, laser cutting has lower energy concentration and heat input. Compared with fine plasma cutting and flame cutting, the heat-affected zone is relatively small and the heat input is small. It is suitable for ferritic stainless steel that is easy to grow grains and easy to quench. High-strength steel with a hard tendency is of great significance and is conducive to improving the quality of welds.
7. Low-cost laser cutting for small batch production
In mass production, the process of die blanking is selected for processing, mass production, the cost of making molds is evenly distributed to each part, and its production cost is low. However, if it is a small batch production, the die blanking process is adopted, not only the die production cycle is long, and the timeliness of parts processing cannot be met, but the die manufacturing cost is evenly distributed to each part, and the processing cost is relatively high.

With the changes in the automobile manufacturing industry and the integration of the global economy, various automobile manufacturing enterprises have transformed from the original single, large-scale national railway car production to small-scale, multi-variety export vehicles. This transformation has also brought revolutionary changes to the manufacture of auto parts. The frequency of use of the original sheet metal processing equipment such as shearing machines and punching machines is getting lower and lower. Instead, laser cutting equipment plays an irreplaceable role because of its advantages of processing high-precision, small-size, complex-shaped accessories, and being able to process a variety of materials.
