During the use of the laser cutting head of the fiber laser cutting machine, you notice black spots appearing on the lens. The solution for this case is to not affect the cutting quality of the machine. Please read the article shared by Vietweld.

<1> Black spots appearing on the laser cutting head

Firstly, the black spots on the protective lenses are primarily accumulations of debris on the lens, hence highlighting the importance of regularly inspecting and cleaning the protective lens. If not detected timely, lenses with black spots can affect the light transmission of the protective mirror, impacting the focal length, causing the laser beam to not focus well on the surface of the material, affecting the cutting; more seriously, it can cause the protective mirror layer to thin out and get punctured, then lose its protective effect, leading to damage to the laser head.

Solution:

Generally, black spots on the protective lens are difficult to remove because they have adhered to and invaded the protective lens. At this point, the protective mirror is no longer usable and must be replaced with a new one.

If you want to slow down the appearance of black spots on the protective mirror, you should start with the device itself. The most important thing is to reduce spatter. Simply put, these are issues related to cutting quality of the workpiece, requiring checks on focal point, power, side force, combined with the workpiece machining quality adjustments.

[1] Create a small and uniform bead

Possible causes: 1. Focusing position too low 2. Feed rate too high

Solution: 1. Raise the focusing position 2. Reduce the feed rate

[2] Both sides produce uneven long beads, surface of the large sheet discolored

Possible causes: 1. Focusing position too high 2. Feed rate too low 3. Low auxiliary air pressure 4. Material is hot

Solution: 1. Lower the focusing position 2. Increase the feed rate 3. Increase air pressure 4. Cool the material

[3] Only uneven long beads produced on one side of the cutting edge

Possible causes: 1. Focusing position too high 2. Feed rate too low 3. Low auxiliary air pressure 4. Misalignment of the nozzle

Solution: 1. Lower the focusing position 2. Increase the feed rate 3. Increase air pressure 4. Center the nozzle

[4] Waste ejected from above

Possible cause: 1. Feed rate too high 2. High auxiliary air pressure 3. Power too high

Solution: Press the pause button immediately to prevent spatter from hitting the focusing mirror. Increase power and reduce speed and feed pressure
