Regular maintenance of a laser cutting machine is essential to ensure precision, efficiency, and longevity. Below is a comprehensive checklist for routine maintenance:

1. Daily Maintenance

• Check Optical Path:

  • Inspect lenses and mirrors for contamination or damage. Clean with lens paper and alcohol if needed.

  • Ensure proper alignment of the laser beam.

• Cooling System:

  • Check coolant levels and quality (if water-cooled).

  • Ensure the chiller is functioning correctly.

• Gas Supply:

  • Verify pressure levels of assist gases (O₂, N₂, compressed air).

  • Check for leaks in gas lines.

• Machine Exterior & Worktable:

  • Clean debris, dust, and metal slag from the cutting area.

  • Lubricate guide rails and bearings if necessary.

• Nozzle & Consumables:

  • Inspect the nozzle for wear or clogging. Replace if damaged.

  • Check focus lens condition.

2. Weekly Maintenance

• Motion System:

  • Clean and lubricate linear guides, ball screws, and racks.

  • Check belt tension and alignment.

• Ventilation & Dust Extraction:

  • Clean filters and ducts to prevent blockages.

• Electrical Components:

  • Inspect wiring, connectors, and grounding for wear or looseness.

• Laser Source (CO₂/Fiber):

  • Monitor laser power stability (for CO₂ lasers, check gas purity and tube condition).

3. Monthly Maintenance

• Full Optical Path Inspection:

  • Realign mirrors and lenses if needed.

  • Replace damaged optics.

• Cooling System Deep Clean:

  • Flush and replace coolant (if water-cooled).

  • Clean radiator fins and check pump performance.

• Mechanical Components:

  • Tighten screws, nuts, and belts.

  • Inspect servo motors and drives.

• Software & Calibration:

  • Update firmware if necessary.

  • Recalibrate cutting parameters (focus, power, speed).

4. Quarterly/Annual Maintenance

• Laser Source Maintenance (CO₂):

  • Check gas pressure and refill if needed.

  • Test resonator performance.

• Fiber Laser Check:

  • Inspect fiber cables for damage.

  • Clean collimating and focusing lenses.

• Comprehensive System Check:

  • Test safety interlocks, emergency stops, and sensors.

  • Replace worn-out mechanical parts (belts, bearings).

Additional Tips:

✔ Keep a maintenance log to track servicing schedules.
✔ Use high-quality consumables (lenses, nozzles, gases) to avoid premature wear.
✔ Train operators on basic troubleshooting to minimize downtime.

By following this maintenance schedule, you can prevent unexpected breakdowns, maintain cutting quality, and extend the machine’s lifespan.
