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, and chemical cleaning often still has residues.
Laser de-esterification can altogether remove esters and mineral oil without damaging the surface of the part. The following introduces the cleaning application of laser cleaning machines in precision instruments.
Laser cleaning can also be used to remove oil and ester in the processing of mechanical parts. Shock waves accomplish the removal of pollutants. The thin layer of oxide on the surface of the parts explosively vaporizes to form shock waves, which lead to the removal of dirt instead of mechanical interaction.
Laser cleaning technology mainly uses the characteristics of high laser energy, high repetition frequency, and high power to hit a high-energy-density beam on a small area on the surface of the object to be cleaned. The difference in laser absorption capacity between the substrate material and the attachment is used to make the thing. The extensions or coatings that “hide dirt” on the surface “evaporate” or peel off instantly.
Laser cleaning does not require the use of any chemicals, and the cleaned solid waste is easier to store and recycle.
The “soft and invisible” light will not cause “secondary damage” such as mechanical effects on the equipment surface and high cleanliness. At the same time, laser cleaning has high efficiency, less time, and low use cost. Although the initial investment of a laser cleaning system is relatively high, the cleaning system can be used stably for a long time with low operating prices. More importantly, it can be easily automated.
The above is the precise de-ester cleaning application of laser cleaning machines in precision instruments. With the rapid development of lasers and people’s continuous in-depth research on laser cleaning mechanisms, surface quality monitoring and characterization methods are becoming more complete and more comprehensive in the field of industrial application. Laser cleaning The surface quality of the material has been improved, and the cleaning accuracy and efficiency have gradually increased.
