Daily Maintenance Checklist for Fiber Laser Cutting Machines: Keep Your Machine Running at Peak Performance

Maintenance

Fiber laser cutting machines are precision tools that require regular maintenance to deliver consistent, high-quality results. Daily care not only extends the life of the machine but also minimizes downtime, reduces repair costs, and improves cutting efficiency.

To help you maintain your equipment in top shape, here’s a daily maintenance checklist every operator should follow before and after each shift.

✅ Pre-Operation Checklist (Start of Shift)

1. Power Supply & Air Pressure Check

• ✅ Ensure stable voltage supply and air pressure is within the required range.

• ✅ Check for proper operation of the air compressor and filters.

2. Clean the Lens & Nozzles

• ✅ Inspect protective lens for dust, smoke stains, or scratches.

• ✅ Use lens-grade cleaning wipes and solutions to clean the lens.

• ✅ Check the cutting nozzle for debris or burn marks and clean or replace as needed.

3. Check Laser Head Alignment

• ✅ Visually inspect the laser head for misalignment or mechanical damage.

• ✅ Confirm proper focus and zero-point calibration.

4. Inspect Gas Lines

• ✅ Check oxygen/nitrogen gas levels and pressure.

• ✅ Look for leaks or blockages in gas hoses and connections.

5. Machine Bed & Slag Removal

• ✅ Clear the work area and cutting bed of metal scraps and slag.

• ✅ Inspect and clean the support grid if needed.

✅ During Operation Checklist

6. Monitor Cutting Quality

• ✅ Look for signs of burrs, poor edge quality, or inconsistent cuts.

• ✅ Adjust speed, power, or gas settings as needed.

7. Check Cooling System

• ✅ Ensure chiller is functioning properly and coolant levels are sufficient.

• ✅ Verify water temperature is within recommended limits.

8. Listen for Abnormal Noises

• ✅ Be alert for unusual vibrations or noises indicating mechanical issues.

✅ Post-Operation Checklist (End of Shift)

9. Clean Machine Surfaces

• ✅ Wipe down the machine exterior, control panel, and working area.

• ✅ Remove dust, oil, and residues from the surfaces.

10. Lubricate Moving Parts

• ✅ Apply recommended lubricants to guide rails, linear bearings, and drive systems.

• ✅ Follow manufacturer instructions for lubrication frequency and product type.

11. Backup and Log Data

• ✅ Save cutting parameters, maintenance logs, and error reports.

• ✅ Report any irregularities or malfunctions to the maintenance team.

12. Shutdown Procedure

• ✅ Follow proper shutdown sequence.

• ✅ Power off the laser source, cooling system, and main control panel.

🔧 Pro Tips

• Keep a daily logbook or digital checklist to track maintenance routines.

• Always wear PPE (gloves, eye protection) during cleaning and inspection.

• Schedule weekly and monthly maintenance for deeper inspections and part replacements.
