Laser cleaning machines adopts a laser beam to irradiate the surface of an object, and through the physical or chemical interaction between the laser and the contaminants,so that to realize dust removal, coatings and other contaminants from the surface of metals, ceramics and other materials. Laser cleaning machines ensure that the cleaning process is efficient and precise, while avoiding damage to the substrate. Compared with traditional cleaning methods, laser cleaning does not require the use of any chemical reagents without producing waste water, exhaust and other pollutants, in line with the high demand for environmental protection in modern industry. Laser cleaning machine is widely used in aerospace, automobile manufacturing, electronic appliances, cultural relics protection and other industries.
