How does a laser engraving machine work?

Laser engraving technology is one of the laser processing technologies. Laser engraving is a marking method that uses high-energy and high-density laser light to irradiate the workpiece locally, causing vaporization or color change of the surface material and eventually permanent marking. Laser engraving can produce different words, symbols, and patterns. Laser engraving works by using a focused beam to mark the surface of the material. As the beam interacts with the surface of the material, it changes the properties and appearance of the material. This focused beam is aimed at only a specified area, allowing laser engravers to create precise, high-quality, high-contrast marks on virtually any surface. The most common laser is the fiber laser, which has a wavelength of about 1um, and the laser light energy is easily absorbed by metals, plastics, and ceramic materials. Therefore, it can process almost all metals and most plastics. It can also be used to engrave harder materials if you can provide higher power.

Features of laser processing

Laser engraver has no direct contact with the surface of the material to be processed, it is not affected by mechanical movement, so the surface of the material will not be deformed. Since it is not affected by the elasticity of the material, it is very suitable for processing soft materials.

Conclusion

Laser engraving process is to use laser as the processing medium, so that the processing material will be vaporized or color change under the irradiation of high temperature laser. In combination with CNC technology, the laser moves in a certain path to achieve the purpose of engraving.
