In the field of laser cleaning technology, both CO2 laser cleaning machines and fiber laser cleaning machines are widely used. However, when it comes to preserving the integrity of the substrate, which one is less damaging? In this article, we will discuss the cleaning effect, roughness of the substrate surface after cleaning, and cleaning efficiency of both CO2 and fiber laser cleaning machines.
Cleaning Effect
Both CO2 and fiber laser cleaning machines have excellent cleaning effects. They are capable of removing various contaminants such as rust, paint, grease, and oxides from different types of substrates. The high-energy laser beams emitted by these machines efficiently break down the molecular bonds of the contaminants, allowing them to be easily removed from the surface.
Roughness of Substrate Surface after Cleaning
When it comes to maintaining the surface quality of the substrate, fiber laser cleaning machines have an advantage. The laser beam in a fiber laser cleaning machine has a shorter wavelength, which leads to higher precision and a smaller heat-affected zone. As a result, the surface roughness of the substrate after cleaning is significantly reduced. In comparison, CO2 laser cleaning machines may cause slight roughness on the substrate surface due to the longer wavelength of the laser beam.
Cleaning Efficiency
In terms of cleaning efficiency, both CO2 and fiber laser cleaning machines are highly efficient. They are capable of removing contaminants quickly and effectively. However, fiber laser cleaning machines have a slight advantage in terms of speed, as they can achieve higher scanning speeds due to the smaller spot size of the laser beam. This enables faster cleaning over larger areas.
In conclusion, both CO2 and fiber laser cleaning machines provide excellent cleaning effects. However, if preserving the smoothness of the substrate surface is of utmost importance, fiber laser cleaning machines are more suitable, as they minimize the roughness of the cleaned surface.Additionally, fiber laser cleaning machines offer slightly faster cleaning due to their smaller spot size. Ultimately, the selection between the two types of machines should be based on the specific requirements and priorities of the cleaning application.
