Routine Maintenance of The Optics

The optics of a fiber laser cutting machine affect the laser's performance, so it is important to ensure they are free from scratches, dirt, and dust.

The optics are also very thin and fragile, so it is important to follow strict cleaning procedures to maintain them daily.

Note: When the lenses show scratches or non-cleanable dirt, you need to replace the lenses again.

This is why lenses are one of the most fragile parts we need to pay extra attention to in our maintenance routine.

The following steps are described for replacing lenses:

Preparation for maintenance of optical lenses

1.Dress cleanly, preferably with clean medical gloves

2.Ensure that there is no significant dust in the air during disassembly

3.Prepare cotton swabs or lens wipes, alcohol or isopropyl alcohol, and lens storage paper

Precautions when replacing lenses

1.Do not blow into the lens with your mouth after removing it.

2.When removing the lens from the laser head, always hold it gently and be careful not to crush it with too much force.

Steps to follow when replacing the optical lens

1.Remove the laser head with gloves, then carefully remove the lens and 2.place it on the lens storage paper

3.Wipe the area where the optic is fixed with a cotton swab dipped in alcohol or a special cleaning solution for lenses

4.Then gently hold the edge of the lens and wipe it clean with a cotton swab

5.After wiping the lenses, slowly clean the area around the lenses

Then reinstall the lenses in order

Note: How can you tell if the lenses have been cleaned? By holding the cleaned lenses in a lighted position, you can see if there are any stains on the lenses.

Laser beams are difficult to focus

As part of the routine optics maintenance, ensuring that the beam is level with the focusing mirror after each cleaning is also important. If the beam path is shifted, it will be easier to focus, and the cut will improve. The most obvious effect will be slag on the surface of the cut metal or vertical lines on the cut surface.
