How to adjust the optical path of fiber laser cutting machine?

The laser cutting machine itself uses a flying optical path system. During long-term work, the optical path will have a slight deviation, which will have a great impact on the cutting effect. Therefore, it is very necessary to check the light path and adjust it regularly. How to adjust the optical path of the fiber laser cutting machine, have you learned these tips?

　　1. Check whether the laser can hit the first mirror, if not, adjust the position of the first mirror.

　　2. Check whether the laser can hit the second and third mirrors. If not, adjust 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 to see if it is at the same position as the spot hit on the upper right corner. If not, adjust the M1, M2, and M3 screws of the second reflector to make it hit The point is at the same position as the point in the upper right corner.

　　4. Paste at least two layers of double-sided tape at the light entrance of the laser lens barrel, move the laser head to the upper right corner of the table and press the TEST button on the control panel to hit a laser spot.

　　5. Move the laser head to the lower left corner, observe whether the dot is at the same position as the upper right corner, and adjust the second reflector.

　　6. Repeat the adjustments mentioned in 4 and 5 above, so that the three laser points hit the same position.

　　7. Check whether the focus is in the center: place a mirror vertically below the focusing lens, and place a transparent plastic sheet close to the lens barrel under the lens barrel (ie, hold it in hand) and press the TEST button to hit the laser to see if the laser spot hits In the center of the focusing lens. Be careful of laser burns when holding the plastic sheet, and do not put your hands within the vertical plane of the lens.

　　 After learning the above seven tips, we can ensure that we adjust the optical path of the fiber laser cutting machine. For us, the adjustment of the optical path of the laser cutting machine is very important, but the adjustment process is also very complicated. Therefore, we should be careful enough when setting up. Only careful setting can ensure that the accuracy of the fiber laser cutting machine is good.
