The precision machinery industry often needs to remove the esters and mineral oils used for lubrication and corrosion resistance on the parts, usually by chemical methods, but chemical cleaning often still has residues. Laser cleaning machine can completely remove esters and mineral oil without damaging the surface of parts. The following describes the cleaning application of laser cleaning machine in precision instruments.
Laser cleaning machine can also be used for the removal of oil esters in the processing of mechanical parts. The removal of pollutants is completed by shock waves. The explosive vaporization of the oxide layer on the surface of the parts forms a shock wave, resulting in the removal of dirt, rather than mechanical interaction.
The laser cleaning technology mainly uses the characteristics of high energy, high repetition rate and high power of laser to hit the beam with high energy density on the small area of the surface of the object to be cleaned, and makes use of the difference between the base material and the attachment's laser absorption ability to make the attachment or coating on the surface of the object "hide dirt" instantly "evaporate" or peel off.
The laser cleaning machine does not need to use any chemical agent, and the solid waste after cleaning is easier to store and recycle. The "soft and invisible" light will not cause mechanical effects and other "secondary damage" to the equipment surface, and the cleanliness is high. At the same time, the laser cleaning system has high efficiency, less time and low use cost. Although the one-time investment in the purchase of the laser cleaning system is relatively high, the cleaning system can be used stably for a long time with low operation cost. More importantly, it can easily realize automatic operation.
The above is the application of laser cleaning machine in precise de-ester cleaning of precision instruments. In the field of industrial applications, with the rapid development of lasers and the continuous deepening of research on laser cleaning machines, the surface quality monitoring and characterization methods are becoming more complete and comprehensive, the surface quality of laser cleaning materials is improved, and the cleaning accuracy and efficiency are also gradually increasing.
