Sheet metal fiber laser cutting machine has many commonly used accessories, some of which are fragile and consumable parts, which are consumable accessories. Generally, laser cutting machine manufacturers will give some accessories to customers when they sell laser cutting machines, but if they are used for a long time, they will be given away. The part is not enough. In order to ensure production efficiency, a lot of accessories are generally prepared to ensure the normal operation of the fiber laser cutting machine in case of emergency.
So, what are the specific accessories?
一. Reflective lens In a typical laser system, there may only be one or two transmissive optical elements, which are usually used as the output mirror of the laser cavity and the focusing lens at the end. On the other hand, in some other laser systems, there may be five or more reflective lenses. Reflective lenses are used as tail mirrors and refracting mirrors for laser cavity and beam steering in beam delivery systems.
二. Beam expander The beam expander is a lens assembly that can change the diameter and divergence of the laser beam.
3. Protective lens The main function of the laser protective lens is to block the splash of debris and prevent the splash from damaging the lens. Both sides are coated with high damage threshold anti-reflection coating to reduce reflection. (The general replacement period of these lenses is about 3 months, depending on the actual processing conditions).
4. The copper nozzle can assist the gas to be ejected quickly, which can effectively prevent the melting stains and other debris from rebounding, thereby protecting the focusing lens. At the same time, it can control the gas diffusion area and size, which will affect the cutting quality of the laser cutting machine. At the same time, the nozzle aperture size will vary according to the thickness of the cut material. The replacement cycle is about two months.
5. Ceramic ring Ceramic ring is an important part of the cutting head of the fiber laser cutting machine; its main function is to transmit the electrical signal collected by the laser head nozzle, which plays an important role in the normal and stable operation of the fiber laser cutting machine. We often encounter equipment shutdown for no reason, laser head hitting the working surface and other failures are actually caused by the unstable or missing electrical signal caused by the poor laser ceramic ring. Therefore, it is very important to choose a high-quality laser ceramic ring for the fiber laser cutting machine. .
