Description

[0002] Laser cutting is a technology that laser beam focuses through a focusing lens to concentrate energy at the focal point and produce high-density energy, and after reaching the material surface, a light spot is formed, the material absorbs heat at the light spot and rapidly melts to form a molten material or even vaporizes, the molten material flows out from the cut under the dual action of gravity and the dynamics of auxiliary airflow, thereby realizing material removal, and with the movement of the laser beam, non-contact, high-speed and high-precision cutting is realized.

After the impurities such as oil stains, dust, and oxide layers on the surface of the material are cleaned, the laser beam can accurately act on the pure surface of the material. The cleaned surface of the material will not produce additional impurities during the laser cutting process, avoiding chemical reactions between the impurities and the material to change the microstructure and chemical composition of the cutting surface, so that the quality of the cutting surface meets the high-quality industrial standards.

[0026] 2. By arranging the polishing mechanism, the surface of the material to be laser cut can be polished.

During the cleaning process, especially when cleaning materials that are prone to dust, spraying water can inhibit the generation of dust. When the surface of the material is polished and cleaned, if water is not sprayed, the stone powder generated by polishing will diffuse in the air, which not only harms the health of the operator, but also pollutes the surrounding working environment. Spraying water can reduce the diffusion of dust in the air, maintain the air quality of the working place, and also meet the environmental protection requirements. BRIEF DESCRIPTION OF DRAWINGS
