The main reasons are the laser head optical path, laser power supply, and airflow cutting. When the focus of the laser lens is gentle or dirty, it can affect the laser energy changes on the material surface, resulting in inability to cut. At the same time, if the laser power supply voltage is unstable, it will cause the laser power supply to be unstable and also cause opacity. If the gas supply pressure in the air circuit is insufficient or the nozzle is damaged, it will also cause opacity.

To effectively avoid the problem of decreased processing quality during laser production and processing, the following points should be done as much as possible:
① Choose a suitable laser based on the thickness of the processing board and do not use laser batch processing to limit its cutting ability. If the laser limit cutting thickness is, the laser batch processing thickness should be within.
② Design appropriate cutting patterns for different thicknesses of plates, and in principle, avoid machining patterns with dimensions smaller than 0.8 times the thickness of the plate. When the thickness of the plate is relatively thick compared to the laser cutting ability, the cutting sharp corners can be correspondingly changed to rounded corners or pulse cutting to avoid corner burning.
③ Reasonably arrange the cutting sequence to avoid high-density cutting in the same area in a short period of time.
④ Choose a suitable cutting process to avoid batch processing of sheets at the maximum cutting speed.
⑤ Improve the perforation process to avoid unstable perforation causing dirt on the cutting head lens and nozzle damage.
⑥ Choose a suitable water cooler to ensure that its flow rate and cooling capacity meet the needs of the laser.
⑦ Ensure the purity of cutting gas and the stability of output gas pressure.
Any mechanical equipment has its service life, including CNC spindles, laser cutting machines, laser engraving machines, etc. Therefore, it is recommended to pay more attention to operation and maintenance in daily life, including the configuration of laser industrial chillers, which is beneficial for extending the service life of the equipment and achieving high production efficiency in long-term continuous production and processing.
