The cleaning technology of laser cleaning machine refers to the process of using high-energy laser beam to irradiate the workpiece surface, so that the dirt, rust or coating on the surface can evaporate or peel off instantaneously, so as to achieve cleaning and purification.

The mechanism of laser cleaning is mainly based on the absorption of laser energy by pollutants on the surface of the object, or vaporization, or instantaneous thermal expansion to overcome the adsorption force of particles on the surface, so that the laser cleaning can adapt to the cleaning of various surface pollutants, with minimal environmental pollution and no damage to the substrate.
