Laser cleaning technology refers to the use of high-energy laser beams to irradiate the surface of the workpiece, so that the dirt, rust or coating on the surface of the workpiece evaporates or peels off instantly, and effectively removes the attachments or surface coatings on the cleaned surface. Objects are processed at high speed, enabling the cleaning process. It is very easy to install and operate. It can be used without chemical reagents, media, dust-free and water-free cleaning, and has the advantages of automatic focus, surface cleaning with cranks, and high surface cleanliness. Laser cleaning machines can remove surface oil, dirt, rust, coatings, paints, etc.
