Laser marking technology, an integral part of laser processing techniques, finds widespread application across various industries. Given the high cost of laser marking machines and their frequent usage, regular maintenance is crucial to prevent damage that could impact the quality and speed of marking, as well as the machine’s longevity. This article outlines simple maintenance practices for both operational and non-operational states of laser marking machines, specifically focusing on maintaining products from leading manufacturers like Han’s Laser.

Maintenance During Operation

1.Proper Startup and Shutdown

Always follow the specified startup and shutdown procedures for your model. Abruptly turning off the machine can cause significant damage.

For example，startup procedure for Han’s Laser flying laser marking machine

• Check if the emergency stop switch is released; turn the emergency stop switch clockwise to release it.
• Connect the machine to an external power supply.
• Close the air switch.
• Turn the key switch clockwise to the “ON” position indicated by “LOCK.”
• Press the “POWER” button to power up the control box.
• Turn the selector switch clockwise to the “ON” position indicated by “LASER.”
• Wait for the touch screen to display the marking software interface. Import the required marking files from the software to start marking. If using the probe trigger method, select “Lower Machine 10 Trigger Marking” in the marking dialog box.

2.Electrical Safety

During operation, the machine’s circuit is under high voltage. Non-professionals should not attempt any repairs while the machine is on to avoid the risk of electrocution.

3.Avoid Overloading

Do not place items on the laser marking machine as this can obstruct proper heat dissipation and affect performance.

4.Emergency Shutdown

In the event of a malfunction, use the emergency stop switch to cut power immediately to prevent accidents.

5.Signal Interference

Never connect any signal cables to the machine while it is powered on.

6.Water Cooling Systems

If your machine uses a water cooling system, ensure the water circulation is appropriate before starting the machine. Improper water flow can damage the laser.

Maintenance When Not in Operation

1.Power Off

When the machine is not in use, disconnect the power to both the laser marker and the computer. Cover the lens to prevent dust accumulation on optical components.

2.Voltage Stability

Before using the machine, check that the power supply voltage is stable and within normal parameters. Operating the machine under unstable voltage conditions can lead to damage.

3.Water Tank Maintenance

For water-cooled models, it’s advisable to clean the water tank and change the water regularly, such as weekly or monthly. Repeated use of the same water can degrade its quality, affecting the laser tube’s lifespan. Use distilled water and keep the temperature below 35°C (95°F).

4.Cleaning Optics

Dust in the air can settle on the focusing lens, reducing the laser power and marking quality. In severe cases, it can cause the optical lenses to overheat and shatter. Operators should clean the lenses weekly to ensure they are free of dirt and stains.

5.Handling the Laser Source

The laser source is the heart of the marking machine. Handle it with care to avoid any damage due to improper movement.

Conclusion

Regular maintenance of your laser marking machine is essential to ensure its efficient operation and extend its service life. By following these straightforward guidelines, you can minimize downtime and maintain the high quality of your marking processes. Whether during active use or periods of inactivity, proper care of your machine is a critical component of operational success in any high-tech environment.
