Laser engraving processing is based on CNC technology and laser is the processing medium. The processing material instantly melts and vaporizes and physically changes under laser irradiation to achieve the purpose of processing. Features of laser processing: There is no contact with the material surface, it is not affected by mechanical movement, the surface will not deform, and generally does not need to be fixed. It is not affected by the elasticity and flexibility of the material and is convenient for processing soft materials. The processing precision is high, the speed is fast, and the application fields are wide.
