Five Daily Checks for Laser Marking Machine Operators

If you are a beginner, pay attention! Here is a list of the five most important daily checks to perform on your laser marking machine, including aligning the beam path, cleaning the lenses, and checking the parameters. These tips will help you quickly master the basics of maintenance, avoiding small oversights that can lead to equipment failure or processing errors.

1. Do not skimp on the optical system.

Before turning on the machine in the morning, you should first feel the temperature of the laser head housing. If it is still hot from the previous evening's overtime, it is best to wait until it has cooled completely before starting work.Open the protective cover and check to see if there is any mist on the optical lens. Especially in the south during the rainy season, the lens will fog up just like a pair of glasses. If you don't wipe it off in time, it will affect the results of the marking.

The lenses should be kept clean.

Don't just wipe the lenses with the corner of your shirt! Instead, use a professional dust-free cloth and a drop of pure alcohol, and wipe the lenses from the center outwards in a spiral motion.If you encounter a stubborn stain, don't rub too hard. Just change to a new cotton ball.Remember to check the surface under a light when you are done. If you see a rainbow pattern, you have to start over.

Parameters must be realistic.

Newcomers are most likely to be lazy and just use yesterday's parameters, but a difference in material thickness of 0.5 mm or a change in environmental temperature will affect the results.Every day, first use the leftover material to practice the standard shapes, focusing on whether the lines are continuous and whether the depth is even. Don't wait until the finished product has been scrapped to regret it.

A small trick for adjusting the focal length.

When adjusting focus, don't just look at the scale. Put a sheet of A4 paper in the engraving position, and raise and lower the work table slowly.When the red light forms the smallest dot on the paper, you have achieved the best focus. This method is much more intuitive than simply looking at the numbers.

3) Keep a close eye on the cooling system.

Before leaving work, he feels the temperature of the water entering and exiting the chiller. If the difference is less than 3 degrees, it's time to be on guard.Remember to refill the water tank to the mark every day, and don't wait until the warning light comes on.The dust filter on the heat dissipation fan should be cleaned at least twice a week. A blocked fan is like running with a mask on.

Listen to the sound of the water.

When you turn it on, put your ear close to the pump. If it's working properly, it should make a steady humming noise.If you hear a rattling like pebbles rolling, it's probably air bubbles in the pipe.The valve must be opened quickly. If the water flows continuously without air bubbles, the test is passed.

4.

Wipe down the guide rails and screws every day, and don't forget to apply a little oil, but don't use butter! Just a thin layer of special white grease will do.The X and Y axes are run through their full range of motion, and the machine is listened to for any unusual noises. Sometimes a tiny piece of metal stuck in a track can cause the machine to lose its precision.

The belt test.

Press the middle of the belt with your thumb. It should sink in about 5mm.If it's too tight, the motor will heat up quickly; if it's too loose, the motor will skip teeth.The feel is like pressing fresh bread.

5. Don't count on luck.

If your screen has a scratch, replace it immediately. Don't think you can still make do with it.Emergency stop button: Tested by pressing each one individually every day before work. This life-saving device is no laughing matter.When the laser warning light dims, replace it immediately.

Don't forget to check the grounding.

If the red light comes on, it means there's a short circuit.Grounding screws should be tightened once a month, especially in areas where heavy equipment is causing vibrations. A loose ground is more dangerous than no ground at all.
