Reasons for the heating of the nozzle of the laser cutting machine:
1. Is the cooling air (cooling water) of the laser nozzle turned on? whether the requirements are met.
2. The laser focusing optical path may be offset, and part of the laser is irradiated on the nozzle.
3. The diameter of the laser nozzle is partially blocked or polluted.
The nozzle of the laser cutting machine is hot, and the following measures can be taken to solve it:
1. Check whether the cooling air is turned on, and turn it on if it is not turned on.
2. Check whether the focus is correct, if not, adjust it.
3. Check whether the nozzle is blocked, and clean it if it is blocked.
4. Do not work continuously for a long time, and let the equipment cool down regularly.
