How to Tell When the Mirrors of a Laser Cutter Need to Be Replaced

The condition of the mirrors in a laser cutting machine has a direct impact on the quality of the cut and the machine's lifespan.By observing a drop in the quality of the cuts, or yellowing or scratches on the lenses, and combining this with the information from the strong light inspection and the equipment's alarm signals, it is possible to quickly decide whether the lenses need to be replaced.Regular maintenance and replacement of components is required to keep the system running smoothly, and it is best to replace parts with those made by the manufacturer.

When should I change my lenses?

If the mirror in a laser cutting machine is not changed regularly, it will not only affect the cutting effect, it may even damage the machine.You can use these factors to judge whether or not you need new glasses.

The quality of the cuts has declined dramatically.

If the edge of the cut is rough or you can't cut all the way through the material, don't rush to blame the machine for being old. First check to see if there are any scratches or dirt on the surface of the lens.Sometimes you can clean a lens and it can still be used, but if problems persist after repeated cleanings, then it's time to retire that lens.

The lenses turn yellow or cloudy.

Long-term high-power work can cause the coating on the lenses to age, making the surface look foggy and the transmission rate drop.If you get to this point, it's no use trying to fine-tune the parameters; you have to change the lens.

A few tricks for checking your own lenses.

You don't have to wait for a problem to occur to take action. Regular inspection can save a lot of money in maintenance costs.

Shine a flashlight on it.

After turning off the equipment, shine a flashlight at the mirror at an angle.If you see obvious pits, cracks or scratches, then the lens is worn out.Remember, even a single deep scratch will cause laser scattering!

Be aware of any unusual messages.

Most of the equipment we have now has intelligent detection functions.If your machine frequently reports "insufficient laser power" or "abnormal optical path" on the control panel, don't just click "ignore." Check the state of the lenses first.

What should you pay attention to when changing lenses?

Don't be tempted to buy cheap, unbranded products.

Poor quality lenses can break after just a few uses, or damage the laser head.I recommend using original equipment or a big brand, even though they are more expensive. They last twice as long.

Don't shake your hands when you install them.

The lenses are especially sensitive to fingerprints and dust. When installing them, wear gloves and use tweezers to gently grasp the edges.After installation, wipe the lenses with a professional cleaning cloth.
