Daily Maintenance and Color Stability Assurance for Laser Marking Machines

The manual explains in detail how to perform routine maintenance on a laser marking machine, and how to ensure the stability of the mark color. It covers cleaning and maintenance, parameter calibration, environmental control, and other key topics, helping users prolong the life of the equipment and improve marking performance.

Three steps to daily maintenance.

Clean the lenses and the optical path.

The mirrors and optical path of a laser marking machine are like its "eyes." If they are contaminated with dust or grease, the marking effect will be greatly reduced.I suggest that people wipe the surface of the lenses with alcohol and a special cloth once a week. The motion should be light, and you shouldn't press too hard.Also, check that the beam has not shifted, and if the light is not evenly distributed, contact the manufacturer to adjust the machine.

Checking the cooling system.

The equipment produces a large amount of heat when it is working for a long time. If the cooling fans and ventilation ports become clogged, the precision of the marking will be affected, and in severe cases, parts may be damaged.Clean the fan's filter once a month, using a soft brush to sweep away accumulated dust.In the hot summer, you can use a small fan to help cool the equipment and prevent the machine from being "heatstruck.

Lubrication of moving parts.

Metal parts like rails and ball screws are prone to rust and wear.Once a quarter, apply a thin layer of special lubricating oil to the rails.If he hears a squeaking sound from the equipment, it means that the lubrication is insufficient and he must deal with it immediately.

The technique of color stabilization.

Materials and parameters.

The absorption rate of different materials varies greatly, with different materials requiring different levels of power.Before engraving, you must first test the machine on the corner of the material to be engraved in order to adjust the power and speed settings.Some experienced workers record the "golden parameters" of different materials, so that the next time they can just use them directly, doubling efficiency.

Control of humidity.

Moist air causes the laser's energy to weaken, and during the rainy season in the south the color of the markings tends to fade.A hygrometer is placed in the workshop to keep the humidity between 40 % and 60 %.If the humidity is too high, you can use an air conditioner to dehumidify the air or place a desiccant near your equipment.

Replace worn parts on a regular basis.

Although the laser and the galvanometer have long lifespans, the focusing lens and ceramic ring should be replaced regularly according to the manufacturer's instructions.Don't try to save a few dollars by using worn-out components, because this can result in inconsistent color and slow down production.

What do you do if the colors aren't even?

First, he checks the lens for dirt, then he confirms that the surface is flat.If neither of these are the problem, it could be that the laser is not stable.Try resetting the power parameters, or reduce the marking speed by 10-15 %.If you really can't solve the problem, you can contact the manufacturer's technical support department. Sometimes it's better to get a professional to walk you through the solution over the phone than to struggle with the problem yourself for hours.
