Use only approved optical cleaning solutions and lint-free wipes, handling lenses by their edges. Replace protective windows as soon as they show signs of pitting or cloudiness.
• Check Nozzle Alignment and Condition: The nozzle must be perfectly centered with the laser beam for optimal cutting. Regularly inspect the nozzle for wear, deformation, or buildup. A worn Single Nozzle or Double Nozzle will scatter the assist gas and lead to poor cuts.
• Inspect and Replace Ceramic Rings: The laser cutting machine ceramic ring is vital for stable height sensing and electrical insulation. Inspect it for cracks, chips, or carbon buildup. Replace it promptly if damaged to prevent head crashes and ensure consistent cutting height.
• Maintain Cooling System: Ensure the chiller operates effectively, maintaining the correct water temperature and flow. Regularly check water filters and replace them to prevent contaminants from circulating through the laser source and cutting head.
• Lubricate Moving Parts: Keep guide rails, bearings, and gear racks clean and properly lubricated according to the manufacturer's recommendations. This prevents premature wear, ensures smooth motion, and maintains cutting accuracy.
• Clean Dust Filters: Regular cleaning or replacement of air and dust filters (for both the machine and exhaust system) is essential to maintain a clean operating environment and prevent particles from damaging sensitive components.
