1、 The lifespan of the nozzle has expired
The service life of the laser cutting machine nozzle is limited, usually around 500 hours. If it exceeds the service life, both cutting quality and economic benefits will be affected, and a new nozzle needs to be replaced.
2、 Damaged nozzle
The laser cutting machine nozzle is prone to damage, such as nozzle deformation, wear, burning holes, etc. If not replaced in a timely manner, it will affect the cutting quality and even cause the nozzle to completely fail.
3、 Change gas type
When cutting different materials, it may be necessary to replace different types of gases, and different gases have specific requirements for the material and shape of the nozzle. If the nozzle is not replaced, it will cause poor gas flow and affect the cutting quality.
4、 Decreased cutting quality
If it is found that the cutting quality of the laser cutting machine has decreased, it may be due to the accumulation of dust, oil stains or blockage inside the nozzle, and the nozzle needs to be replaced at this time.
5、 Slow cutting speed
The wear and blockage of the nozzle can also cause the cutting speed of the laser cutting machine to slow down, and it is necessary to replace the nozzle to restore normal cutting speed.
In short, the timing of replacing the laser cutting machine nozzle should be determined according to the actual situation. When encountering the above situations, it should be replaced in a timely manner to ensure the normal operation and cutting quality of the laser cutting machine.
