What are the categories of laser precision laser processing?

Speaking of traditional manufacturing, our country is now facing a deep transformation and upgrading with high added value. High-end precision processing is undoubtedly a very important direction, among which is the precision laser processing that we are familiar with. So what are the categories of precision laser processing of lasers?

1.Laser Precision Cutting

Compared with high-power laser cutting, nanosecond precision cutting is usually used for laser precision cutting, and picosecond lasers can focus on ultra-fine spatial areas. At the same time, it has very high peak power and very short laser pulses. During the processing, it will not affect the surrounding materials involved in the spatial range, thereby achieving "ultra-fine" processing.

Such as cutting mobile phone screens, fingerprint recognition sheets, and LED laser precision cutting technology has incomparable advantages in production processes with high precision requirements.

2.Laser precision welding

Laser precision welding can weld metals with high melting points or materials of different thicknesses. Laser welding, as the standard welding standard in the field of power batteries, is widely used in welding at the front end, bottom cover in the middle, top cover, welding sealing nails, rear battery connectors, and negative electrode sealing welding. In the C field, various mobile phone modules, mid-plate covers, etc., are inseparable from laser precision welding technology.

Third, Laser precision punching

Laser precision punching is to reduce the spot diameter to micron level, so as to obtain high laser power density, and almost any material can be laser punched. Its characteristics are high hardness, small hole diameter, fast processing speed and high efficiency for drilling holes in fragile or soft materials.

Fourth, laser surface treatment

The characteristics of laser surface treatment are that it does not require the addition of materials, only changes the organizational structure of the surface layer of the processed material, and the processed parts are less deformed, which is suitable for surface marking and high-precision parts processing.

Laser surface treatment can be divided into two categories according to whether the substrate composition is changed. The application of laser quenching (phase change hardening) does not change the substrate composition, laser cleaning, laser shock hardening and laser polarization, including laser melting, including laser melting, laser electroplating, application of laser alloying and laser vapor deposition.

Industry Status

With the increasingly fierce market competition environment, Chinese equipment manufacturers have entered the market with world-class technical competitiveness and low-cost solutions, which has greatly promoted the marketization process of laser technology.
