Fiber Laser Cleaning Machine Cleaning Marble Material
Fiber laser cleaning machines are primarily used for removing rust, paint, oxide layers, and contaminants from metal surfaces. However, they can also be used for cleaning certain non-metallic materials like marble, but with caution due to the risk of thermal damage.
Can a Fiber Laser Clean Marble?
Yes, but under controlled conditions. Marble is a calcium carbonate-based natural stone that is sensitive to heat and high-energy laser beams. If the laser parameters are not optimized, it can cause discoloration, burning, or surface etching.
Key Considerations for Cleaning Marble with a Fiber Laser
Laser Power & Pulse Duration
Use low power (20W–50W) to avoid overheating.
Short pulses (nanosecond lasers) are better than continuous-wave (CW) lasers to minimize heat accumulation.
Wavelength
Most fiber lasers operate at 1064 nm, which is absorbed well by dark contaminants but may also affect the marble if settings are too high.
A green laser (532 nm) could be more precise for delicate cleaning.
Scanning Speed & Spot Size
Higher scanning speeds reduce heat buildup.
A larger spot size distributes energy more evenly, reducing the risk of burning.
Surface Contaminants
Organic stains (mold, algae)
Thin paint or graffiti
Dust and grime layers
Works well for removing:
Not ideal for deep stains or heavy coatings.
