In order to meet the upgrading needs of export and domestic in the automobile manufacturing industry, the production of small batches and varieties of vehicles has become the norm. The original processing technology of general automobile body parts can no longer fully meet the current product quality and production needs. The fiber laser cutting machine has the characteristics of high-precision processing, faster cutting speed, easy integration, which plays an irreplaceable role.
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. Fiber laser cutting equipment can process it.
2. High-precision processing
Fiber laser cutting equipment has higher processing precision 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 laser cutting produce less slag during processing.
4. High utilization rate of materials
When cutting accessories, you can cut different accessories with the same thickness and material, and make full use of the leftovers of the raw materials.
5. Low cut roughness value
When cutting accessories of the same material, fiber laser cutting equipment 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 lower.
6. Small heat affected zone
During 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 plasma cutting and flame cutting, the heat-affected zone is relatively small and the heat input is small. It is suitable for cutting ferritic stainless steel that is easy to grow grains and easy to quench and high-strength steel with a hard tendency, and it is conducive to improving the quality of welds.
7. Low-cost for small batch production
In mass production, the process of mold blanking is selected for processing, and the cost of making molds is evenly distributed to each part in mass production is low. However, if using die blanking process in a small batch production, not only the mold production cycle is long which can’t meet the timeliness of parts processing, but also the processing cost is higher when mold cost is evenly distributed to each part.
Therefore, CNC cutting is generally used for processing. Due to the weak perforation ability of plasma cutting, the low cutting precision and the poor forming quality of the hole, another drilling process needs to be added, and a drilling mold needs to be made. Not only the processing time is longer, but the cost is also higher. So it’s not suitable for automobile manufacturing.
Fiber 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 needs to be comprehensively considered according to the size, shape, cost and accuracy requirements of the accessories. When the size of the accessories is small and the shape size and positioning size of the holes are required to be high, it is more economical to use the laser cutting method. With the changes in the automobile manufacturing industry and the global economic integration, various automobile manufacturing enterprises have transformed from the original single, large-scale production to small-scale, multi-variety exports. This transformation has also brought revolutionary changes to the manufacture of auto parts. The original sheet metal processing equipment such as shearing machines and punches are used less and less. CNC fine plasma cutting machines and CNC flame cutting have been replaced by CNC flexible equipment such as fiber laser cutting machine.
Newlaz is devoted to retrofitting Bystronic and Trumpf CO2 laser cutting machine to fiber laser cutting and has help more than one hundred customers all around world upgrade their machine. If you’re interested, welcome to consult. Also you can click the laser retrofit to get more info.
