The Impact of Laser Maintenance on Marking Quality

The book also explains the critical impact of daily maintenance of laser equipment on the quality of the mark, and shares practical tips on how to improve the clarity of the mark.They know how to use standards to avoid problems such as blurred markings and broken lines, which can extend the life of their equipment and ensure stable production.

The reasons for maintaining the mark have a direct impact on the outcome.

All of our laser equipment users have encountered this situation: the marks were clear just a few days ago, but suddenly the lines have become faint and the patterns blurry.In most cases, these problems are related to inadequate maintenance.For example, dust on the lens will weaken the laser's power, and a lack of lubrication on the guide track can cause the marking to be interrupted.

This is a problem that arises from not cleaning properly.

Last month, an old client who makes metal nameplates complained that the letters were turning yellow. It turned out that a layer of oil had condensed on the focusing lens.After the ink has dried, the paper can be peeled off and the print is complete.I suggest that you spend five minutes every day before you shut down your computer cleaning the optical drive and the ventilation ports with a cotton swab," he says. "Don't underestimate the effect of these little bits of dust.

The most critical component is the replacement cycle.

The laser tubes and mirrors are like the "heart" and "fingers" of the equipment, and any damage to them will have a direct impact on precision.According to our ten years of experience in maintenance, you need to check for power decay after a CO2 laser has worked 2000 hours. Don't wait until it has completely stopped working before you change it.If the mirror motor makes an unusual sound, it's probably because the bearings are worn.

The cooling system--easy to overlook.

In summer, it's usually the water cooling system that causes trouble. One customer who did leather engraving had impurities in the cooling water clog the pipes, causing the laser head to overheat. The resulting marks were burned and blurred around the edges.Remember to change the distilled water every three months, and add algae control tablets to the tank. The temperature should be 22 ° C ± 3 ° C.

The golden rule of parameter calibration.

Don't blindly follow the initial settings given by the manufacturer.I'll teach you a little trick: First, put a cross mark on the film, then check the lines. If the vertical line isn't crooked and the horizontal line isn't broken, the focus is correct.If the material starts to discolor, you should reduce the power to 70 % and try again. This is often more effective than just blasting away at 100 %.

The importance of maintenance records.

The workshop director, Old Wang, has a good habit: after each maintenance he puts a note on the machine, which reads: "Replace filter on July 15.This kind of record which can be seen by all can help operators to develop the awareness of maintenance, which is more effective than ten sets of rules.I suggest that everyone set up a reminder on their cell phone and prepare a replacement part two weeks before the expiration date of the important component.
