In the process of metal laser cutting machine, auxiliary gas and nozzle play the role of cleaning and controlling cutting speed. The uneven pressure and temperature in the air flow will cause the change of the density of the air flow field, which will dry the focusing of the beam energy, cause refocusing or beam divergence, and affect the metal cutting accuracy.
The position of air nozzle (also known as nozzle) in laser cutting machine is undoubtedly very important, because the use of air nozzle will have a great impact on the laser beam.
The gas nozzle of metal laser cutting machine (also known as nozzle) is a consumable, because sparks will inevitably splash on the gas nozzle and burn the bottom light hole during long-term use. It generally needs to be replaced once every three months. The laser has an anti-collision function for the laser cutting head to prevent the cutting head from hurting the gas nozzle due to misoperation.
Some sheet metal factory operators are very careful and operate in a standard way. They haven't hit the laser head for 8 months. They clean up the impurities on the laser head in time after work every day. They adjust the light path every day before starting processing. They haven't replaced the air nozzle for 8 months, and the air nozzle is still fresh when it is removed. Therefore, it is recommended to maintain the cutting head every day, which is beneficial to prolong the service life of the air nozzle consumables of the metal laser cutting machine.
