Five Ways to Reduce Laser Marking Machine Noise

If the laser marking machine is making too much noise, here are five practical solutions to help you reduce the noise quickly and improve the work environment.

Why does your laser marking machine sound like a construction site?

When they hear the clattering noise of a laser marking machine, many people think that the machine is about to break down.In most cases, it is just a few minor problems that are causing trouble.Don't rush to call a repairman. First try these quick-fix solutions.

Inspecting the installation environment.

Is the ground solid?

Vibrations in the machine will amplify the noise, and a tiled floor is especially prone to resonance.Check with a level to see if the four feet of the equipment are level, and if necessary place rubber vibration pads underneath. These are much more effective than placing iron sheets underneath.

Don't pile up other objects around it.

Leave at least a 30-cm space between the wall and the object. Metal materials and boxes of accessories placed next to the wall are most likely to resonate with sound waves. Clearing away clutter within a 1-meter radius can reduce noise by 20 %.

The main focus is on maintaining the parts of the machine.

A little "moisturizer" for the tracks.

When the tracks run dry, they make a loud, grating sound.Use a dust-free cloth to apply a thin layer of lubricant to the X / Y axis guide tracks. Remember to move the sliders as you apply the lubricant, and don't just smear it on in one big lump like butter on a slice of bread.

Listen to the fans and you will hear what they are saying.

When dust accumulates on the cooling fan, it can't turn smoothly, and it makes a loud whirring sound.After the power is cut off, use compressed air to blow in the opposite direction of the exhaust (be careful not to spin the blades too quickly). Clean at least twice a year.

A simple, effective way to reduce noise.

A soundproof room.

Three sides of the equipment are surrounded by 5 mm thick acrylic, with the operating side left open, while an inner layer of sound-absorbing cotton is also attached.Don't be fooled by the low cost of the material, however. Tests have shown that this approach can reduce high-frequency noise by more than 40 % without adversely affecting heat dissipation.

The carpet has a miraculous effect.

Underneath the equipment, they laid a 2-cm-thick industrial anti-slip mat. Don't look down on this simple trick: It is particularly effective in absorbing low-frequency vibrations.Choose a design with a rubber sole. It will not only be non-skid but will also not collect dust.

The settings that are often overlooked.

Bigger isn't always better.

Many people think that the higher the power, the more efficient the laser, but in fact any energy beyond what is needed for the material will just make the galvanometer motor work harder.Under the condition that it does not affect the marking effect, if you lower the output by 10 to 15 %, the equipment will run much more quietly.

A balance of speed and quietness.

The scan speed was raised from 800 mm / s to 1200 mm / s, while the jump delay was shortened by 30 %, "says Chen.This way, efficiency is maintained and the "clack" sound produced when the mirror is suddenly stopped and then started again is avoided.

Replaceable parts should be replaced.

The old bearings should retire.

If the machine has been used for two years or more, it is a good idea to check the main spindle bearing.If there is a steady hissing sound, then the bearings need to be replaced.

There are rules for the tightness of the belt.

If the belt is too tight, it will squeak, but if it's too loose, it will slip.Press your finger into the middle of the belt. The ideal amount of give is 5-8 mm.When adjusting the machine, remember to first loosen the screws that hold the motor in place.
