Daily cleaning
Optical lens cleaning: Use a dust-free cloth dipped in isopropanol to wipe the focusing lens and reflector every week to avoid fingerprints and dust, which can reduce laser power.
Chamber dust removal: Clean the interior of the equipment with compressed air every month to prevent dust accumulation from affecting heat dissipation.
Water cooling machine maintenance: Regularly replace the cooling water (deionized water), check the water pump flow and temperature sensor to avoid overheating of the laser.
Life management of key components
Laser tube replacement: The lifespan of CO ₂ laser tubes is about 8000-10000 hours, and the lifespan of fiber lasers is>100000 hours. It is necessary to record the usage time and prepare spare parts in advance.
Maintenance of galvanometer motor: Check the lubrication of the galvanometer motor bearings every quarter to avoid lagging and misalignment of markings.
Field lens calibration: Use a laser interferometer to calibrate the field lens focal length annually to ensure marking accuracy.
Common fault handling
Laser power reduction: Check for lens contamination, laser tube aging, or power failure, and gradually troubleshoot.
Blurred marking: Adjust defocus, frequency, or speed parameters, or replace auxiliary gases (such as nitrogen instead of air).
Mirror shaking: Check the signal line connection of the drive board or replace the mirror motor.
