How to adjust the focusing of fiber laser cutting machine

As we know,if you want to have a better cutting effect,we need to adjust the focusing before cutting.So this article is about how to adjust the focusing of fiber laser cutting machine.

1. Testing cut, observe cutting section to judge if the focus point is too big or small. Slag (too big), Grain (to small).
2. Turn on the focal point control panel before cutting head to do manual focal point adjust.
3. When focal point data is 0, turn the focusing wheel to the left, then do cutting test.
4. When the focal point data is too small, there is slag at the rough bottom of the surface of the cutting sample (the focus is too small to cut through).
5. When the focal point data is +5 or bigger, turn the focusing wheel to the right, then do cutting test.
6. Cutting surface has obvious pattern on when the focal point data is too large.
7. After cutting test, observe the cutting surface and adjust the focusing wheel till the right data.
8. When the focal point is at the right place, the surface of the sample is smooth and without hanging slag.
9. Finish the testing.
10. Focusing adjust for carbon steel ( the same as manual laser cutting head focusing)
12. Focusing adjusting for stainless steel (the same as manual laser cutting head focusing)
