Lasers are widely used in fine processing, mainly in the following aspects:

1. Laser cutting

Laser cutting can achieve micron-level cutting accuracy, which is difficult to achieve with traditional mechanical cutting methods. The high-power density laser beam can quickly and accurately penetrate the material, while the high-speed airflow coaxial with the beam blows away the molten material to achieve high-precision cutting. This technology is particularly important in the manufacture of high-precision parts such as microelectronic devices and optical fiber communication devices.

2. Laser marking/engraving

Laser marking/engraving technology can mark and engrave on the surface of materials such as metals and plastics with high precision. The laser beam generates local high temperature on the surface of the material, causing physical or chemical changes on the surface of the material, leaving permanent and clear marks or patterns. This technology is widely used in the fields of precision instrument identification, anti-counterfeiting labels, etc., and is of great significance for increasing product added value and anti-counterfeiting traceability.

3. Laser welding

Laser welding also performs well in the field of fine processing. It can achieve fast and precise welding with high weld quality and small deformation. When welding microelectronic components, precision mechanical parts, etc., laser welding can ensure the precise docking and firm connection of the welding parts, meeting the high-precision processing requirements.

4. Laser drilling

Laser drilling technology can realize the processing of tiny holes, and the hole diameter can be as small as micron level. This technology has important applications in microelectronics, biomedicine, aerospace and other fields. For example, in the field of microelectronics, laser drilling technology is used to manufacture tiny through holes in integrated circuits; in the field of biomedicine, laser drilling technology is used to manufacture tiny holes and channels in medical devices.

5. Laser surface treatment

Laser surface treatment technology can change the physical and chemical properties of the material surface and improve the wear resistance, corrosion resistance and other properties of the material. This technology is particularly important in the manufacture of high-performance mechanical parts. Through laser surface treatment, a dense oxide film or alloy layer can be formed on the surface of the part, thereby improving the service life and performance stability of the part.

6. Laser 3D printing

Laser 3D printing technology is an additive manufacturing technology that uses a laser beam to melt and solidify powdered materials layer by layer to construct a three-dimensional solid model. This technology has great potential in the field of fine processing and can produce parts with complex shapes and high precision. Through laser 3D printing technology, rapid design and manufacturing of parts can be achieved, product development cycle can be shortened, and production efficiency can be improved.

In summary, the application of laser in fine processing covers cutting, marking/engraving, welding, drilling, surface treatment and 3D printing. These technologies play an increasingly important role in the manufacturing industry with their advantages of high precision, high efficiency and high reliability.
