Laser engraving refers to laser engraving processing. Laser engraving processing is based on the use of numerical control technology, and laser is the processing medium. The physical denaturation of instantaneous melting and vaporization of the processing material under the irradiation of laser engraving can enable laser engraving to achieve the purpose of processing. Laser engraving is the use of laser technology to engrave text on objects. The words engraved by this technology have no nicks, the surface of the object is still smooth, and the writing will not wear out.
 
Principle: The high-intensity focused laser beam emitted by the laser is used at the focal point, so that the material can be exposed to the deep layer through the evaporation of the surface material, or the chemical and physical changes of the surface material can be traced by light energy, or part of the material can be burned by light energy. , and "carved" traces.
