Laser has high brightness, high directivity, high monochromaticity and high coherence, which are incomparable to ordinary lighting sources. After focusing, the laser beam can produce thousands or even tens of thousands of degrees of high temperature at the focus, making it possible to process almost all materials.
Laser marking is to use laser beam to engrave permanent marks on the surface of various substances. The effect of marking is to expose deep substances by evaporation of surface substances, or "carve" traces by chemical and physical changes of surface substances caused by light energy, showing the graphics and characters to be etched.
Laser marking features:.
1. It can process a variety of metal and non-metallic materials, especially for high hardness, high melting point and brittle materials.
2. It belongs to non-contact processing, does not damage the product, has no tool wear, and has good marking quality.
3. The laser beam is thin, the processing material consumption is small, and the processing heat affected zone is small.
4. High processing efficiency, computer control, easy to achieve automation.
