In long-term operation, many accessories will be lost, especially those commonly used. Laser cutting machines have many commonly used accessories that should be replaced in a timely manner based on their lifespan or damage. In order to ensure the normal operation of production, some processing plants usually prepare many commonly used accessories to ensure uninterrupted production in case of emergencies. The following laser introduces the four common accessories of laser cutting machines:

1. Beam expanding lens

An expansion mirror 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 prevent debris from splashing and prevent damage to the lens or operator by splashing. Coated with high damage anti reflective film on both sides can reduce reflection. The replacement cycle for protective lenses is generally 3 months or determined based on actual situations.

3. Reflector lens

In a laser system, there are usually only one to two transmission optical elements, which are usually used as the output mirror of the laser cavity and the focusing mirror at the end. On the other hand, in some other laser systems, there may be five or more mirrors. The reflector serves as the tail mirror and refractor, used to control the beam direction in the laser cavity and beam transmission system.

4. Copper nozzle

Copper nozzle can help gas spray quickly, effectively preventing impurities such as molten stains from rebounding, thus protecting the focusing lens. At the same time, it can control the size of the gas diffusion area, thereby affecting the cutting quality of the laser cutting machine. Meanwhile, the aperture of the nozzle may vary depending on the thickness of the cutting material. The replacement cycle is generally around two months.

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