Analysis of the four applications of precision processing of fiber laser cutting machine:

Laser precision processing can be divided into four categories of applications: precision cutting, precision welding, precision drilling and surface treatment. Under the current technological development and market environment, the application of laser cutting and welding is more popular, and 3C electronics and new energy batteries are the most widely used fields. Laser cutting processing is used in various manufacturing and processing industries such as sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway accessories, automobiles, food machinery, textile machinery, engineering machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising, metal external processing, kitchenware processing, etc.

1. Laser precision cutting

Compared with high-power fiber laser cutting machines, precision cutting generally uses nanosecond and picosecond lasers according to the processing object, which can focus on ultra-fine space areas, and has extremely high peak power and extremely short laser pulses. During the processing process, it will not affect the surrounding materials in the space range involved, thus achieving "ultra-fine" processing. Laser precision cutting technology has incomparable advantages in production processes that require high precision, such as mobile phone screen cutting, fingerprint recognition sheets, and LED invisible scribing.

2. Laser precision welding

In the field of new energy batteries, with the promotion of new energy vehicles, the demand for power batteries continues to grow. Laser welding, as a standard welding in the field of power batteries, is widely used in the welding of the front ear, the welding of the bottom cover, top cover, and sealing nails in the middle, and the welding of the battery connector and negative electrode sealing in the back. In the 3C field, various modules, middle plate covers, etc. of mobile phones cannot do without laser precision welding technology.

3. Laser precision drilling

What are the applications of laser precision processing of fiber laser cutting machines? Laser drilling is most widely used in the PCB industry. Compared with the traditional PCB drilling process, laser on PCB not only has a fast processing speed, but also can achieve the drilling of small holes, micro holes and invisible holes below 2μm that traditional equipment cannot achieve. On the surface of electronic products, it can also be used for drilling holes in mobile phone speakers, microphones and other glass.

4. Laser surface treatment

Laser surface treatment can be divided into two categories according to whether the substrate composition is changed. Applications that do not change the substrate composition include laser quenching (phase change hardening), laser cleaning, laser shock hardening and laser polarization, while applications that change the substrate composition include laser cladding, laser electroplating, laser alloying and laser vapor deposition.

Fiber laser cutting machine can do both plane cutting and bevel cutting, and the edges are neat and smooth. It is suitable for high-precision cutting of metal plates, etc. At the same time, with the addition of a robotic arm, it can perform three-dimensional cutting instead of the originally imported five-axis laser. Compared with ordinary carbon dioxide laser cutting machines, it saves more space and gas consumption, has a high photoelectric conversion rate, is a new energy-saving and environmentally friendly product, and is also one of the world's leading technology products.
