Seven Steps to Laser Marker Maintenance

Daily maintenance of a laser marking system has a direct impact on the system's performance and stability.The seven-step program includes optical cleaning and cooling system inspection, and helps users reduce downtime, improve marking accuracy, and extend the equipment's useful life.Mastering these techniques will keep your laser equipment running at peak efficiency for the long term.

Clean optical elements.

The lenses and mirrors of the machine are particularly susceptible to dust and oil.If the laser markings become blurry or have spots, it is likely that the optical components are dirty.

Operating Suggestions.

First use a professional air blower to remove surface dust. Then dip a lint-free cotton swab in 99 % pure alcohol and gently wipe in one direction.Remember to wait for the alcohol to evaporate completely before turning the computer on, otherwise you may leave water stains.

Cooling system check.

Lasers generate a lot of heat when they are working. If the cooling water fails, the equipment could overheat and shut down in minutes.

Points to watch for in the daily monitoring of the patient.

Check the water level in the water tank every week. If it is low, check for leaks.Change the water or coolant every three months, and never use tap water, because mineral deposits can clog the pipes.

Maintenance of the guide rails and drive parts.

If a device is making unusual noises or has problems moving, there is an 80 % chance that this is due to lack of lubrication in the guide rails.

The lubrication of operating procedures.

First, wipe off the old oil and metal shavings from the tracks with non-woven cloth, then apply a thin layer of white lubricant.Don't spread it on too thick, or it will attract dust.This should be done at least once a month, and especially if there is a lot of dust in the workshop.

Laser power testing.

If you feel the laser is not striking with enough force, it may be that the laser power has declined.

Self-examination tips.

The power output is measured with the power meter built into the device, and compared to the data for a new machine.If the reading drops more than 15 %, it is recommended that the manufacturer be contacted to recalibrate the device.In general, when engraving, it is best not to run at full power for a long time, because it damages the laser tube.

Back up the software parameters.

Have you ever felt desperate after losing a system's parameters following a crash?

Backup plan.

Every week, he saves the parameters and coordinate calibration data onto a USB flash drive, and makes a copy on his local computer and on his cloud storage.Before updating your software, remember to make a backup.

Grounding and wiring checks.

If your equipment is occasionally leaking electricity, or restarting unexpectedly, the problem could well be poor grounding.

Key points for safety inspections.

A multimeter is used to measure the resistance to ground, which must be less than 4 ohms to pass inspection.Check the power cord for any damage, especially at the connectors, which are the most likely to be damaged.Circuit breakers in distribution boxes should be tightened every six months.

Testing of the entire machine.

After completing all the maintenance, the machine must be tested in full.

Testing methods.

First, they would set the machine to run at a slow speed, and listen for any unusual noises. They would also check to see if the edges of the marked samples were smooth.Finally, it is operated for two hours continuously to ensure that the temperature readings are within the normal range.Deal with problems when they are discovered, and don't let minor faults become major ones.
