Laser Marking Machines: Maintaining the Sense of Touch

Sharing the core technology for maintenance of laser engraving machines, the key to solving the problem of Braille embossing weakening over time.Through daily cleaning, recalibration, and environmental control, the company helps users extend the life of their devices, ensuring that the Braille markings remain clear and stable, and improving the user experience.

Why does the sense of touch of Braille gradually fade?

Many users have discovered that after using a laser engraver for a while, the raised bumps of the Braille are not as noticeable as they were when the machine was first purchased.In fact, this is related to the daily habits of the user, the temperature and humidity of the environment, and the cleanliness of the lenses.For instance, dust buildup can affect the precision of the laser beam's focus, and improper parameter settings can result in uneven depths of the grooves.

You can't slack off on daily cleaning and inspection.

The lens and the rail are two key areas.

The lenses in a laser marking machine are like human eyes, and if they get dusty, they can't "see" as clearly.It is suggested that you use a lint-free cotton swab dipped in rubbing alcohol to gently clean the surface once a week. Don't use ordinary paper towels, which can leave bits of lint behind.The best way to prevent this is to apply special lubricant to the rails once a month.

Don't neglect to keep the vents clear.

If the ventilation holes are blocked, the machine can easily overheat and stop working.If you brush the vents with a soft brush or blow them out with an air hose, especially before use in the summer, you can feel the temperature of the body with your hand, and if it feels hot, you should stop work immediately and have it checked out.

The parameters have to be adjusted "according to the material.

Different materials require different arrangements.

The speed and power required to engrave plastics and metals are definitely different.I suggest testing small samples of material before you make a final decision. With braille, which requires a clear sense of touch, the laser power should be set about 10 % higher than for ordinary engraving. But don't be greedy; if you burn the material too much, it will impair the sense of touch.

Adjust the focus regularly.

Every two months, use the calibration plate to check the laser focus, especially if you are often changing molds.A deviation of one millimeter in focus could result in a depth of cut of 0.2 millimeters, which would be disastrous for Braille.

The control of the environment is more important than you can imagine.

Humidity should be kept at 40 % to 60 %.

If the air is too dry, static electricity will make the dust cling.Northern users should consider adding a humidifier, and southern friends should remember to turn on the dehumidifier regularly, especially during the rainy season.

The ground is also shaking.

Place equipment on a flat cement floor. If it is on a suspended wooden floor, it would be best to put a shock absorber pad underneath.When large machines were operating nearby, we would try to avoid using them at the same time, because the vibrations could affect the accuracy of the carvings.

When you encounter a problem, don't panic.

If you find that the depth of embossing suddenly becomes shallower, first check the following three points: 1) Is the lens clean? 2) Is the material damp? 3) Is the focus position correct?Most minor problems you can fix yourself. If you really can't, call up the after-sales service. Don't just take the laser head apart on your own.

With proper care, Braille inscriptions made with laser markers can last three years or more.Remember, equipment is like a car. It's more cost-effective to do regular maintenance than to wait until something breaks.
