Laser nozzle:
The nozzle can assist the gas to be ejected quickly, which can effectively prevent the debris from bucking up and rebound, thus protecting the focusing mirror. At the same time, it can control the gas diffusion area and size, which will affect the cutting quality of fiber laser cutting machine. What’s more, the aperture size of the nozzle will vary depending on the thickness of the cutting material. The replacement period is about two months.
Laser lens:
The laser protection lens mainly acts on the fiber laser cutting machine to block debris splash during the fiber laser cutting machine working, and to prevent spatter from damaging the lens, and to coat the two sides with a high damage threshold anti-reflection film to reduce reflection. Generally speaking, The replacement period of these lenses is about 3 months, depending on the actual processing conditions.
