Many accessories may experience wear and tear during long-term operation, especially those commonly used. There are many common accessories for laser cutting machines, which should be replaced in a timely manner based on their service life or damage. Some processing plants and manufacturers usually prepare many commonly used accessories to ensure normal production operation, ensuring uninterrupted production in case of unexpected needs. Below, Laser will introduce to you the four common accessories of laser cutting machines:

1. Beam expanding lens

A beam expander is a lens component that can change the diameter and divergence angle of a laser beam.

2. Protective lenses

The main function of protecting the lens is to block debris splashing and prevent splashing from damaging the lens or operator. Plating high damage antireflection film on both sides can reduce reflection. The general replacement cycle for protective lenses is 3 months or depending on the actual situation.

3. Reflector lens

In a laser system, there are usually only one to two transmissive optical elements 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 refractive mirrors to control beam steering in laser cavities and beam transmission systems.

4. Copper nozzle

The copper nozzle can assist in rapid gas spraying, effectively preventing impurities such as molten stains from rebounding upwards, thereby protecting the focusing lens. At the same time, it can control the size of the gas diffusion area, which will affect the cutting quality of the laser cutting machine. At the same time, the aperture size of the nozzle will vary depending on the thickness of the cutting material. The replacement cycle is generally about two months.

The commonly used accessories for the four laser cutting machines mentioned above are also available in the market, but their prices and quality vary. To ensure the cutting quality of the laser cutting machine, it is recommended that everyone purchase original accessories from the original factory.
