What accessories do laser cutting machines need?

Many accessories wear out over time, especially those that are frequently used. There are many common accessories for laser cutting machines, which should be replaced in time according to the service life or damage. In order to ensure the normal operation of production, some processing plant manufacturers generally prepare many commonly used accessories to ensure that production will not be interrupted in emergency situations. The following laser will introduce 4 common accessories of laser cutting machine:

1. beam expander

A beam expander is a lens assembly that changes the diameter and divergence angle of a laser beam.

2. Protective lenses

The main function of the protective lens is to prevent debris from splashing and prevent the splash from causing damage to the lens or the operator. Anti-reflective coatings on both sides reduce reflections. The replacement cycle of protective lenses is generally 3 months or according to the actual situation.

3. Reflector

In a laser system, there are generally only one or two transmissive 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 mirrors. Mirrors are used as tail mirrors and catadioptric mirrors to control beam steering in laser cavities and beam delivery systems.

4. Copper nozzle

The copper nozzle can assist the rapid injection of gas, which can effectively prevent debris such as molten stains from bouncing upwards, thereby protecting the focusing lens. At the same time, the size of the gas diffusion area can be controlled, which will affect the cutting quality of the laser cutting machine. At the same time, the aperture size of the nozzle varies according to the thickness of the cutting material. The replacement cycle is generally about two months.
