High summer temperatures accelerate cooling water degradation, increase chiller system pressure, and cause lens contamination — all of which reduce laser cutting performance. The most critical summer maintenance tasks are monitoring chiller pressure, replacing cooling water weekly with distilled water, and cleaning optical lenses daily.

Problem
Cause
Impact on Cutting
Reduced cutting power
Elevated cooling water temperature
Incomplete cuts, edge dross
Optical lens damage
Increased dust and contamination
Beam quality loss, focus errors
Chiller system failure
Higher operating pressure in heat
Emergency shutdown, tube damage
Electrical faults
Condensation from temperature changes
Control system errors
5 Essential Summer Maintenance Steps
1. Check Chiller Pressure Before High Temperatures
As ambient temperature rises, the cooling system operates at higher pressure. Before the peak summer season, inspect the chiller pressure gauge and verify it falls within the manufacturer's recommended range.
2. Replace Cooling Water Weekly
Use distilled or deionized water only — tap water contains minerals that form scale buildup
Clean the water tank when replacing water
Recommended schedule: Weekly water replacement during summer months
3. Clean Optical Lenses Daily

Action
Important Notes
1
Remove the lens carefully
Handle by the edges only
2
Wipe gently with lens cleaning tissue
Do not scratch the anti-reflective coating
3
Use approved optical cleaning solvent
Never use acetone or abrasive cleaners
4
Install focusing lens with concave side downward
Incorrect installation damages the lens
4. Prevent Scale Buildup in the Cooling System

Higher temperatures accelerate water degradation and mineral precipitation. Clean the cooling system scale regularly using methods recommended by your machine manufacturer.
5. Clean the Electrical Cabinet
Clean the electrical cabinet monthly
Check that cooling fans are functioning properly
Inspect wiring connections for signs of corrosion
Post-Maintenance Protocol
After completing any maintenance, do not immediately resume production. Run a trial cut on scrap material to verify the machine is operating correctly before processing valuable workpieces.
