There are many commonly used consumables for optical fiber laser cutting machine, which need to be replaced from time to time according to the length of use. In order to ensure production efficiency and make the machine work for a long time, the equipment purchaser will generally reserve the consumables, so that they can be replaced at any time to ensure the normal operation of the machine. What are the commonly used consumables? Let's take a look:
1. Reflector lens: In a typical laser system, there may be only one or two transmission optical elements, 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. The reflective lens is used as the tail mirror and refractor in the laser cavity and the beam steering in the beam transmission system;
2. Protective lenses: the laser protective lenses are mainly used to prevent debris splashing and damage the lens. Both sides are coated with high damage threshold antireflection film to reduce reflection;   
3. Nozzle: it can assist the rapid ejection of gas, effectively prevent the upward rebound of impurities such as melting stains, and thus protect 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. At the same time, the aperture size of the nozzle will vary according to the thickness of the cutting material.
