Method 1: Cleaning the lens of a metal laser cutting machine can be done by following these steps. First, take a lens cleaning paper and fold it into several folds. Next, dampen the folded paper with a small amount of analytical pure acetone. Make sure not to touch the lens with your fingers and gently wipe the surface of the lens using the soaked paper. Repeat this process several times until the lens surface is clean and free from any dirt or marks. Afterward, dry the lens and roll a lens paper with a few drops of acetone into a rod shape. Use this rod-shaped paper to scrub the lens surface and remove any stubborn dirt or stains. It is important to properly seal and store the acetone to prevent it from absorbing excessive moisture and getting deteriorated or polluted. Lastly, it is advisable not to mix the used acetone solution with the original bottle and use the principle of pouring only as much as required, discarding any excess.
Another way to clean the mirror lens on a metal laser cutting machine is to remove the lens first. Once it's removed, place a paper on the mirror surface so that the surface is facing up. Next, put a few drops of acetone onto the paper and gently pull it over the mirror surface. Repeat this process several times until the mirror surface is completely dirt-free. Finally, put the lens back into the holder and you're good to go. This method is effective in ensuring that the mirror surface is spotless and enhances the performance of the metal laser cutting machine.
