1. After processing with a laser cutting machine for a period of time, the nozzle is very hot
1. The aperture of the 3mm nozzle should be in the following thin plates φ 1mm, in this way, the cutting gap will be finer, and if it is larger, it will be thicker, and the position of the cutting angle will not be too smooth.
2. 3mm or above, cut thick plates below, select φ The 1mm nozzle aperture is unstable. If the power is high, the cutting time will be longer because it requires heat dissipation time. If the aperture is too small, although heat dissipation is fast, it is still unstable. At this point, select φ 1.5mm, when the heat dissipation area is large, the airflow will slow down, so cutting will be more stable.
If the above plate is selected for cutting, a larger diameter nozzle should be selected. Therefore, there are certain principles for selecting the nozzle of laser cutting machines.

What is the reason for the nozzle heating of the laser cutting machine?
It should be that the cooling system has not achieved effective cooling effect. Suggest checking whether the cooling capacity of the chiller meets the cooling needs of the laser cutting machine
Then replace the large cooling capacity chiller, hoping it will be helpful to you.
Does the nozzle of the laser cutting machine affect the cutting quality?
Influential nozzles and nozzles with poor quality have an impact, and the cutting flatness is very obvious
