Laser cleaning can be a powerful tool for removing unwanted substances from various surfaces. However, when faced with a layer of stain, thick urethane, and another layer of stain on beautiful mahogany wood, unexpected challenges can arise. Typical stain removal parameters may not be effective in such complex scenarios, requiring a methodical approach to find the right solution.
Identifying the Problem
In this particular project, the team encountered a stubborn combination of layers that traditional methods could not easily penetrate. The goal was to break down the surface finish without causing damage to the underlying wood.
Engineering a Solution
Using methodical Engineering principles, the team carefully adjusted the settings of the 300W Pulsed 15mJ fiber laser to find the optimal parameters for this unique challenge. By tweaking the Lens F254, Power 300W, Repeat Frequency 50khz, Pulse Width 50ns, Scan Frequency 20,000 Hz, and Scan Spacing 1000um, they were able to isolate the combination that would effectively remove the stubborn layers.
Overcoming the Challenge
Through systematic testing and analysis, the team was able to determine the precise settings needed to break down the tough stains on the mahogany wood. Once the stain was broken down it could be removed with light scraping to remove the loosely attached pieces.
When faced with unexpected challenges in laser cleaning, it is essential to approach the problem with a methodical and systematic mindset. By understanding the principles behind laser technology and carefully adjusting the parameters, even the toughest stains can be effectively removed.
