Difficulties in aluminum plate cutting

Aluminum plate has always been a difficult problem for us to cut by laser, because aluminum plate is a high-reflective material, its absorption rate to laser is low, and it is difficult to cut aluminum plate by laser. However, because of its wide processing demand, we have to think about how to cut aluminum plate quickly and safely by laser.
 

Laser cutting aluminum plate can be cut by some means to reduce the difficulty before, such as blackening the surface of aluminum plate, which reduces the reflection degree of aluminum plate, and then cutting; At the same time, another reason for the difficulty of aluminum plate cutting is that the parameters of the laser machine are not easy to adjust. Compared with ordinary metal materials, the cutting process is difficult to grasp, and the cut is relatively rough and easy to hang slag.

Key points of aluminum plate cutting

In fact, there are many high-reflective materials like aluminum. Because the laser equipment is really sensitive to the return light, it may run unstable or damage the laser lens during the processing process, and it needs a high-power laser, which greatly shortens the life of the laser. In the process of aluminum plate processing, it is necessary to pay attention to some conditions. The aluminum material is not resistant to high temperature and is prone to burr during cutting. The processing process needs to be patiently adjusted. At the same time, it is easy to burr during cutting because the speed should not be too fast. Too slow cutting speed can cause cracks near the cutting edge, and also affect the cutting quality.

In addition, it is recommended to use nitrogen when laser cutting aluminum plate, because the special color of aluminum material and to ensure the uniform color of the cutting products, nitrogen can effectively prevent oxidation and retain the characteristics of the material itself, so nitrogen is a better choice. The cutting thickness of 2000 to 6-84000 can be cut to less than 126000 to 16. The optical fiber laser cutting machine is more suitable for cutting aluminum plate, and its absorption effect of 1064nm wavelength is better.

Upgrade of laser cutting machine

In modern industrial production, laser cutting is more widely used in sheet metal, plastics, glass, ceramics, semiconductors, textiles, wood, paper and other materials processing, and its application in various heavy industries and light industries is also increasingly popular. Laser cutting accounts for more than 40% of industrial laser processing, and is the most important application technology in the laser processing industry.

In recent years, the laser cutting machine has moved forward in the direction of high power, high precision and large format. With the increase of power, it has also led to the upgrading of laser cutting technology. In this context, major laser equipment manufacturers have followed up the layout and competed to launch new cutting equipment, jointly promoting the upgrading of the laser cutting market.

Aluminum veneer is very common in building materials, and has become one of the fastest growing building materials in China in recent years because of its strong ductility, environmental protection, non-toxic and reusable characteristics. After several years of development, aluminum veneer industry has been used in daily life. House decoration, interior design and building exterior walls are inseparable from aluminum veneer products. As long as you can think of patterns, aluminum veneer can be reflected. With the improvement of people's living standards and the continuous improvement of residents' aesthetic values, the demand for aluminum veneer will only increase. According to the data, the current annual output of aluminum veneer is about 80 million cubic meters, with an annual growth of about 15%. The introduction of the laser cutting machine has greatly improved the production efficiency and made the production enterprises stand out in the highly competitive market.

When processing aluminum veneer with traditional equipment, the plate shears are used first, and then the turret punches are used, which can realize punching and corner cutting on one machine. Now laser cutting is used to improve the cutting speed and efficiency of aluminum veneer by a level, which is 200% higher than the previous production efficiency. The early blanking is the main process of aluminum veneer processing. Because this process cannot be completed, bending, welding and polishing cannot be done later.

The laser cutting machine is very flexible. It can process any pattern, design any pattern, input the program into the system, and then cut according to the pattern. The turret punch can't do it. Engraving machines can also customize patterns, but the speed is too slow, and some materials will be lost, but the laser is not lost. The precision of laser cutting is very high, and the error will not exceed a few millimeters. Its processing accuracy is high, and the precision of the products made will be improved accordingly.

Under the demand of the market, manufacturers continue to penetrate into the aluminum veneer industry, and the competition of enterprises is mainly in product accuracy and production efficiency. As an advanced processing method, laser cutting has outstanding advantages in flexibility, cutting accuracy and efficiency, which naturally meets the production demands of many industries.
