The application principle of CW laser cleaning machine is based on photothermal effect and photomechanical effect: a high-energy-density continuous laser beam irradiates the surface of the workpiece, and the surface contaminants (such as rust, oil, coating) absorb energy instantly, causing a rapid increase in temperature, vaporization or direct peeling, while the base material remains intact due to its low absorption rate or fast thermal conductivity, thus achieving high-precision, non-contact “cold cleaning”.
