Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving machines, in particular to a three-dimensional laser engraving machine. Background Art

[0002] Laser engraving is to focus the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material eventually forms a slit, thereby achieving the purpose of cutting. The laser engraving machine can improve the efficiency of engraving, make the surface of the engraved area smooth and round, quickly reduce the temperature of the engraved non-metallic material, and reduce the deformation and internal stress of the engraved object; it can be widely used in the field of fine engraving of various non-metallic materials.
