Common Failures and Solutions for Laser Marking Machines

The course covered the techniques of laser engraving, the adjustment of parameters, and precision control, and also offered practical solutions to common problems such as power outages, misalignment, and overheating.From daily maintenance to emergency troubleshooting, it covers the full range of core issues in equipment usage, helping operators quickly pinpoint the cause of the problem and get production running again.

This is the core of the laser marking process.

How to choose suitable parameters.

Different materials have different requirements for laser power and speed.For example, metal requires high power and low speed, while the opposite is true for plastic.I would recommend that everyone first use a small piece of material to do a small-scale test, to find the most clear combination of parameters. Don't be in a rush to start printing.

How to deal with unstable marking precision.

If the edges of the markings are blurry or uneven, check first to see if the lens has any dust or scratches.He wipes the workpiece with a cotton swab dipped in alcohol, and checks to see if the workpiece is firmly clamped in place. Sometimes the culprit is vibration.

Common laser marking machine failures and how to deal with them.

Suddenly losing power or having no reaction when turning on the computer.

If the machine suddenly stops working, don't panic. Check to see if the power cord has come loose.If the plug is fine, try holding down the power button for 10 seconds to force a reboot.Most of the time, it's just like when your phone freezes and restarting fixes 80 % of the problems.

The pattern on the label is off-center.

If the patterns run off, it may be because the software parameters have been altered or the drive belt is loose.First, restore the default settings in the control software. If that doesn't work, open the side cover and use a tension meter to check the belt tension. Adjust it so that you can press down about 3 mm.

Laser head overheated.

In the summer, this problem is especially easy to trigger.First, turn off the machine to give it a "breather," and then check to see if the cooling fan has been clogged with dust.When cleaning the air vents with a small brush, remember to wear anti-static gloves and don't let metal particles fall into the circuitry.
