In order to effectively clean the lens of a laser cutting machine to remove oil and water stains, follow these steps:
1.Inspect the Inside of the Cutting Head
- Use a piece of photographic paper to check the inside of the cutting head and ensure there are no oils, water, or other contaminants.
- Place the cutting head on the workbench and remove the copper nozzle to check for any abnormalities.
2.Adjust the Light Path
- The time to adjust the light path typically ranges from 30 to 50 milliseconds. Ensure the time is set accurately.
- After making the adjustments, check the light spot for any black spots. If you find black spots, check the bottom of the cutting head for any issues.
3.Check Components
- Inspect the area around the focus point for any problems. If necessary, remove the air tube and seal its end to prevent dust from entering.
- Remove the protective lens and check both sides for any contamination. Seal the bottom during inspection to prevent dust from entering.
4.Cleaning Process
- Prepare cleaning supplies such as alcohol, lint-free cloth, and cotton swabs.
- Carefully clean all areas that need cleaning.
- Use a small cross-head screwdriver to remove the cover plate and check for any dust inside. If no issues are found, reattach the cover plate.
5.Replace the Lens
- Replace the old lens with a new one. Ensure both the new lens and the installation area are thoroughly cleaned before installation.
6.Final Inspection
- Reinsert the air tube.
- Use a piece of photographic paper to check for any remaining black spots. If no black spots are found, the cleaning process is complete.
7.Test
- Perform a cutting test to ensure the cutting quality has been restored to its best level.
- Check the cutting edge for any burrs. If the cutting edge is smooth and burr-free, the laser cutting machine is working properly.
Summary:
When encountering cutting issues, systematically check and analyze the machine to identify the root cause. Following these steps will ensure the laser cutting machine is restored to its optimal operating condition, improving performance and extending its lifespan.
