ALS maintenance classroom (6) Replace nozzle


ALS maintenance classroom (6) Replace nozzle

 

Precautions: After the nozzle is replaced, it needs to be coaxially calibrated. Coaxiality directly affects the cutting quality. Poor coaxiality will cause one side to be cut well and the other side to be cut badly when cutting the iron plate. That is to say, the laser beam and gas, the laser beam need to be shot from the middle of the nozzle.

 

Preparation tool: transparent tape, new nozzle

 

 

 

Operation steps:

1. Turn off the shutter first, rotate the nozzle clockwise to remove it, and replace the old nozzle

 

 

2. Take out the new nozzle and tighten it anticlockwise

 

 

3. Take a piece of transparent tape and stick it under the nozzle

 

 

4. "Open the shutter" on the remote control panel, and then press "Laser Spot"

 

 
 

 

5. Check whether the light output point is in the center of the nozzle, and the light output point is in the center of the nozzle, which means that the coaxial connection is successful and the cutting can be carried out (if the light output point is not in the center, the position of the lower focus lens needs to be adjusted)
