How to adjust the light path of laser cutting machine?

Laser cutting machines emit high-energy laser beams to cut or etch specific designs on materials such as steel, plastic or wood. It is often used in industrial manufacturing applications and the beam will burn, evaporate or melt away excess product, leaving an excellent finished design or edge. The general steps of adjusting the optical path of laser cutting machine are as follows.


The following knowledge points are listed below:

  • Step1 of adjusting the optical path of laser cutting machine

  • Step2 of adjusting the optical path of laser cutting machine

  • Step3 of adjusting the optical path of laser cutting machine

  • Step4 of adjusting the optical path of laser cutting machine

  • Step5 of adjusting the optical path of laser cutting machine

  • Step6 of adjusting the optical path of laser cutting machine


1. Step1 of adjusting the optical path of laser cutting machine

Adjust the optical path of the laser cutting machine between the laser tube spot and the first reflector. Place the dimmer in front of the first lens, press the test switch by hand (press it immediately, you can see the laser point on the dimmer), and see if this point is in the center of the first lens. If you cannot hit the lens or are too far away from the center, you need to adjust the position or height of the first frame (or laser tube) to meet the above criteria.


2. Step2 of adjusting the optical path of laser cutting machine

Adjust the light path of the laser cutting machine between the first reflector and the second reflector. First, move the second lens of the front dimmer of the laser cutting machine , move the beam X axis to the upper left corner, press the test button where it is located by hand, and then move the beam X axis to the lower left corner, and press the test button. See if the two points (top left and bottom left) coincide. If the light spots overlap and the light spots are located in the lens, the light path between the first and second mirrors is correct; if not, it is necessary to adjust the first lens seat line after the screws enter to the upper left corner of the light spots so that two Light spots overlap. Then adjust the position of the second frame so that the light spot hits the center of the lens.



3. Step3 of adjusting the optical path of laser cutting machine

Adjustment of the optical path of the laser cutting machine between the second reflector and the third reflector (laser head). First move the laser head to the leftmost X axis, and the dimming paper hole in the left laser head, press the test button to reach a point, then move the laser head to the far right of the X axis, and then press the test lightly Button. See if the two light spots are coincident. If the light spots coincide and are at the center of the laser head hole, is the light path correct? If there is no overlap, you need to adjust the screws behind the second frame to the above standard. Then adjust the position of the second lens frame in the front-back direction and the height of the laser tube so that the light beam hits the center of the laser head hole.


4. Step4 of adjusting the optical path of laser cutting machine

Adjust the light path of the laser cutting machine between the third reflective lens and the focusing lens. Install the dimmer on the bottom of the laser head and click the test button to see if the light spot is outside the center of the laser head. If yes, the light path is correct; if not, you need to adjust the three screws on the laser head to make the light spot come from the center of the laser head exit.


5. Step5 of adjusting the optical path of laser cutting machine

After the light path of the laser cutting machine detection is completed, the dimmer is a hole pasted on the left laser head, and the laser head is moved to the upper left, lower left, upper right, lower right, upper left, lower right, lower left, lower right, and lower right. Click the test buttons respectively to check whether the light spots overlap and are located in the center of the left hole. If they overlap, adjust the light path of the laser cutting machine correctly. If they do not overlap, adjust the light path again in steps 3 to 5 until the above conditions are met.



6. Step6 of adjusting the optical path of laser cutting machine

The light path of the laser cutting machine between the lens that adjusts the light path and the angle of adjustment (the angle between the correct path and the lens should be 45 degrees) requires certain basic knowledge, such as: the principle of light reflection, the first time the debugger must follow the instructions If necessary, consult a technician. In addition, the laser has a certain burning ability and invisible light, so the dimming path must pay attention to safety.
