Concentricity Detection

The coaxiality of the nozzle exit hole and the laser beam is one of the important factors affecting the quality of cutting. If the nozzle and the laser are not coaxial, it will affect the inconsistency of the cutting surface. In severe cases, the laser will cause the nozzle to heat up and burn.

Preparation

Dimming steps

1. If the focus of the laser head is not set to 0 on the operating software, change the laser burst power to 100%

2. Replacement of 1.5mm diameter nozzle

3. Attach to the nozzle plane with scotch tape

4. Click the laser shot button and release it immediately

5. Remove the tape and check the imprint, be careful not to turn the direction, there is a circle with the size of the aperture on the imprint, observe if the light spot is in the exact center of the nozzle circle

6. If the light spot is not in the center of the nozzle circle, you need to adjust the position of the light spot by rotating the left and right screws with the Allen wrench until the light spot moves to the center of the circle

7. Adjust it according to the corresponding position of the light spot and the circle

8. After repeated testing and adjustment, the coaxiality adjustment operation is completed until the light spot moves to the center of the circle.
