As a tool, laser manufacturing is gradually discovering new functions. Laser cleaning is a process that has emerged in recent years. It can clean aerospace parts faster, more efficiently, and more accurately, without generating chemical contaminants, making it more environmentally friendly and safe.
There are various traditional cleaning methods, but these are either inefficient or generate a lot of wastewater and dust, which do not meet today's national requirements for environmental protection and green production. Laser cleaning, on the other hand, has the characteristics of no grinding, non-contact, and no thermal effect, and is easy to support dust absorption and purification equipment. It is suitable for cleaning objects of various materials in aerospace, and is considered to be the only reliable and more effective solution.
Laser cleaning is a cleaning solution that uses a high-frequency short-pulse laser as the working medium. A specific wavelength of high-energy beam of light is absorbed by the rust layer, paint layer, and pollution layer, forming a rapidly expanding plasma (highly ionized unstable gas), and generating a shock wave. The shock wave causes the contaminants to break into pieces and be removed.
The beam of light emitted by the laser cleaning machine sweeps the attachments on the surface of the workpiece, just like the broom sweeping the floor, it can be cleaned easily, with high efficiency, and can also control the surface roughness of the substrate without damaging the surface of the substrate, thereby enhancing the comprehensive performance of the substrate surface. Therefore, laser cleaning is considered a black technology.
The scope of laser cleaning is also very wide. At present, Shengtong intelligent laser cleaning machine has been applied in automobile manufacturing, rail transit, aerospace, industrial molds and other fields, including metal steel plates, railway rails, bogies, automobile manufacturing, molds, etc., all of which can be found in direct application scenarios.
