Kiss cutting with a CO2 laser marking machine is a popular technique for producing logos on clothing and shoes, particularly for OEM factories associated with sports brands. However, issues like unstable cutting effects or incomplete engraving are common. This guide outlines solutions to troubleshoot and optimize kiss cutting processes.
Common Kiss Cutting Problems and Solutions
Problem 1: Small Graphics Do Not Close Properly
- Cause: This issue often arises when vector graphics are not properly closed or when software parameters are incorrectly set.
- Solution:
- Check Vector Graphics: Ensure that the vector graphic paths are completely closed in your design software before exporting them to the laser machine.
- Adjust Software Settings: Fine-tune parameters such as light-on delay, light-off delay, jump delay, and laser frequency. Continuously test and adjust these settings until you achieve the best results.
Problem 2: Incomplete Cutting Across a Full Graphics Version
- Cause: This problem may occur due to laser instability, smoke interference, or improper leveling of the work platform.
- Solution:
- Laser Light Instability: Check the motherboard and ensure that the water cooling system is functioning correctly. If the laser output is inconsistent, it can lead to incomplete cuts.
- Smoke Blocking the Beam: Excessive smoke can interfere with the laser beam, leading to inconsistent cutting. Improve ventilation by increasing the effectiveness of the smoke extraction system.
- Platform or Mirror Leveling: Use a level meter to ensure that the work platform and mirrors are properly aligned. Misalignment can cause uneven cutting.
Additional Troubleshooting Points
If the above solutions don’t resolve the issue, consider the following additional factors:
- Focal Length Adjustment:
- Issue: Even if the mirror is set to the correct working distance, the laser focal length may not be aligned with the material surface.
- Solution: Adjust the focal length according to the manufacturer’s reference values to ensure precise focus on the material.
2. Optical Path Misalignment:
- Issue: If the optical path is misaligned, the laser beam might not strike the material correctly.
- Solution: Realign the optical path to ensure the laser beam is accurately directed at the material.
3. Dirty or Damaged Optical Lenses:
- Issue: Dust or damage on the optical system’s lenses can degrade laser performance.
- Solution: Clean the lenses carefully and check for any coating deterioration. Replace lenses if necessary to restore optimal laser performance.
Conclusion
By systematically troubleshooting and addressing each of these factors, you can significantly improve the stability and precision of kiss cutting with a CO2 laser marking machine. Ensuring proper machine maintenance, correct software settings, and optimal alignment will help achieve consistent, high-quality results in mass production environments.
