As a modern precision processing method, laser marking machine technology has unique advantages over corrosion, pneumatic processing, etc.
1. Using laser as an additive means, there is no processing force between the workpiece and the workpiece. It has the advantages of no contact, no cutting force, and small thermal impact, ensuring the original accuracy of the workpiece. At the same time, the adaptability of the material is wide, and it can make very fine marks on the surface of a variety of materials with very good durability.
2. The space and time control of laser is very good. The laser marking machine has a large degree of freedom for the material, shape, size and processing environment of the processing object. It is especially used for automatic addition and special surface processing, and the addition mode is flexible, which can not only meet the needs of laboratory type single design, but also meet the requirements of industrial mass production.
3. The laser marking is fine, and the lines can reach the millimeter and micrometer levels. It is very difficult to forge and change the marks made by laser marking technology, which is important for product security.
4. The combination of laser processing system and computer numerical control technology can form an efficient automatic processing equipment, which can print all kinds of characters, symbols and patterns. It is easy to use the software optical fiber laser marking machine to design the marking pattern, change the marking content, and adapt to the requirements of modern production with high efficiency and fast pace.
5. Laser processing has no pollution source, and it is a clean and pollution-free processing technology with high environmental protection.
Laser marking is a kind of laser processing. In the current domestic market, the laser marking machine may be the most widely used laser equipment in the market. Laser marking is to use laser to carve permanent marks on the surface of various substances. The effect of marking is to expose deep substances through the evaporation of surface substances, or "carve" traces through the chemical and physical changes of surface substances caused by light energy, Or it can burn part of the material through light energy to show the required etched graphics and characters. At present, there are three basic methods for laser marking: mask marking, dot matrix marking, and linear scanning marking.
(1) Laser: It generates high-energy pulsed laser beam or continuous laser beam.
(2) Optical system: it includes focusing lens group, optical fiber, galvanometer scanner, acousto-optic deflection modulator, which is used to guide and focus the laser beam on the marked workpiece processing surface to generate point and line forms.
