Monthly maintenance schedule for laser engraving machines: What should be checked each month?

A monthly maintenance schedule for the laser marking machine includes such key items as cleaning the lenses, checking the cooling system, and lubricating the rails. This helps users extend the life of the equipment, ensure that the marking is precise and stable, and avoid unexpected downtime caused by overlooking details.

Why can't one get away with a little less than a full month's maintenance?

A laser marking machine is like an old friend. The more you use it, the more it will get "testy.The monthly system checks can detect small problems before they become big ones, such as dust on the lenses or a shortage of cooling water.These seemingly minor problems can, if left unattended, lead to equipment failure and production delays.

The five monthly check-ups.

Cleaning of optical surfaces.

First, use a cotton swab dipped in alcohol to gently clean the lens and the mirror, and then blow away the remaining fibers with a blower.Don't rub too hard! The coating on the lens surface is very delicate. After you're done, take a look at the light spot. If it's not round, it's probably because you didn't install the lens properly.

Cooling system check.

First he touches the water tank. If it feels warm he stops the machine.If the water level is below the lowest mark, then distilled water is added.Water pipes and joints are susceptible to leaks as they age. Check for water stains at the joints, and take the opportunity to remove and clean the dust filter on the radiator fan.

Lubrication of the guide rails and the transmission components.

After cleaning the X / Y axes with a dust-free cloth, apply a thin layer of white lubricant.The screw shafts require special lubricant. After applying a few drops of oil, the worktable is pushed manually back and forth several times. If the movement is smooth and free of any sticking, the machine passes.Rusty screws should be replaced with stainless steel ones.

The software and calibration parameters.

Open the control software and first check the version number. If the manufacturer has released an update, don't hesitate to upgrade.The key is to check the speed and power parameters of the laser, and to test the standard graphic on a stainless steel plate. If the edges are fuzzy, the parameters are off.Don't forget to save a copy of the current configuration file!

The power and the line.

Follow the power cord and replace any that are damaged.Open the electrical control box and smell for any burnt smells, and tighten all the terminal screws with a screwdriver.Air switches are the most likely to accumulate dust. You must clean the contact points with a brush, and the contact is good only when you hear a crisp "click" sound.

Don't miss these details.

• Use a vacuum cleaner to clean the inside of the machine, especially the hidden corners around the laser head, to remove dust and metal particles.

• Test the reaction speed of the emergency stop button.

• The level on the worktable must be recalibrated; if it is more than 0.5 ° off, the shot will be inaccurate.

• Inventory of expendable parts should be checked in advance. Don't wait until mirrors or laser tubes break before ordering replacements.

If the machine is maintained according to the schedule, there is no problem in keeping it running for five or six years.If you discover a noise you can't fix or a power drop of more than 20 %, don't try to soldier on--contact the manufacturer's after-sales service.
