The common processing materials of fiber laser cutting machine are stainless steel, carbon steel, aluminum, copper and other materials. Fiber laser cutting technology is developed with the development of the sheet metal processing industry, which plays an important role in promoting the progress of social production.
Optical fiber laser cutting machine has a lot of common parts, some of them are vulnerable consumable, belong to the consumption parts, laser cutting machine manufacturer in commonly sell laser cutting machine will give part of accessories to a customer, but if use for a long time, give part is not enough, in order to guarantee the production efficiency, usually prepare a lot of accessories, ensure the normal operation of the optical fiber laser cutting machine, for a rainy day.So, what exactly are the accessories?
In a typical laser system, there may be only one or two transmission optical elements, usually used as the output mirror of the laser chamber and the focusing lens at the end.On the other hand, in some other laser systems, there may be five or more reflective lenses.The reflective lens is used as tail mirror and folding mirror in laser cavity and beam direction in beam transmission system.
Beam extender is a lens assembly which can change the diameter and divergence Angle of laser beam.
3. Protective lens the main function of laser protective lens is to block debris splash and prevent spatter damage lens. The two sides are coated with anti-reflection film with high damage threshold to reduce reflection.(the replacement time of these lenses is generally about 3 months, depending on the actual processing).
4. The copper nozzle can assist the rapid ejection of gas, which can effectively prevent the debris such as melting stains from bouncing up, so as to protect the focusing mirror.At the same time, it can control the gas diffusion area and size, which will affect the cutting quality of laser cutting machine.At the same time, the diameter of the nozzle varies according to the thickness of the cutting material.The replacement period is about two months.
Ceramic ring ceramic ring is an important part of cutting head of optical fiber laser cutting machine;Its main function is to transmit the electric signal collected by the laser head nozzle.We often encounter equipment unexcused shutdown, laser head impact on the working face and other faults is actually caused by poor laser ceramic ring electrical signal instability or loss of the result of the optical fiber laser cutting machine to choose a high quality laser ceramic ring is very important
