A laser cleaning machine is a device that uses a laser beam to remove contaminants from the surface of materials. It works by irradiating the surface to be cleaned with a laser of a specific wavelength, causing the contaminants to vibrate, vaporize, or decompose rapidly, thereby achieving a cleaning effect. Compared to traditional cleaning methods, laser cleaning machines offer non-contact, non-abrasive, and environmentally friendly features, making them suitable for surface treatment needs in various fields.
