The laser cutting machine itself uses a flying optical path system. During long-term operation, slight deviations in the optical path can have a significant impact on the cutting effect. Therefore, regular inspection and adjustment of the optical path is necessary.

So how to adjust the optical path of a laser cutting machine? What are the skills? Large image laser answers for you:

How to adjust the optical path of a laser cutting machine

1. Check whether the laser can hit the first reflective lens, and if not, adjust the position of the first lens.

2. Check whether the laser can hit the second and third mirrors, if not, the M1, M2, and M3 screws behind the upper mirror.

3. Move the laser head to the upper left corner and hit a laser spot. Observe whether the spot is in the same position as the spot hit at the upper right corner. If not, adjust the M1, M2, and M3 screws of the second mirror to make the spot hit at the same position as the spot hit at the upper right corner.

4. Apply at least two layers of double-sided adhesive tape to the light inlet of the laser lens barrel, move the laser head to the top right corner of the table, press the TEST key on the control panel, and hit a laser spot.

5. Move the laser head to the lower left corner, observe if the dot is in the same position as the upper right corner, and adjust the second reflective lens.

6. The repeated adjustments described in 4 and 5 above make it possible to hit the three laser points at the same position.

7. Check whether the focus is in the center: Place a mirror vertically below the focus lens, and place a transparent plastic sheet (i.e., hold it) under the lens barrel. Press the TEST key to hit the laser to see if the laser spot is in the center of the focus lens. When holding plastic lenses, be careful of laser burns, and do not place your hands within the vertical plane of the lens.

The above seven tips can ensure that we adjust the optical path of the laser cutting machine. For us, adjusting the optical path of the laser cutting machine is very important, but its adjustment process is also very complex. Therefore, we should be careful when setting up, and only careful setting can ensure the accuracy of the fiber laser cutting equipment is the best.
