Key problems brought about by traditional cleaning methods include negative environmental impact and wear on the substrate. Abrasive systems generate large amounts of waste, damaged fragile surfaces, and the use of chemical solvents produces potentially harmful vapors and liquid waste.

The laser cleaning machine came as a result of the need for a nonhazardous, nonabrasive cleaning method which could be used as a substitute for chemical, manual, and abrasive blasting methods.

Laser cleaning is a process that uses laser technology to remove contaminants such as grease, rust, oxides, etc. from metal and other surfaces. It allows selective removal of contaminants with minimal impact on the substrate.

Here are typical industrial application cases of laser cleaning machines.
