What are the common accessories of laser cutting machine?


Many parts of the laser cutting machine will be lost during long-term operation, especially some common parts. If it cannot be replaced in time, it will not only affect the normal operation of the equipment, delay the work cycle, and even damage the laser cutting machine to a certain extent. In order to ensure the normal operation of production, factories and enterprises generally prepare many commonly used accessories to prepare for emergency and ensure uninterrupted production.

Commonly used accessories of laser equipment are generally as follows:


laser beam expander lensand

The beam expander is a lens assembly that can change the diameter and divergence angle of the laser beam. For laser processing, only by adjusting the beam expander to make the laser beam a collimated (parallel) beam, can the focusing lens be used to obtain a small high-power density spot; in laser ranging, only the beam expander can be used to maximize To improve the accuracy of the laser to the limit, the ideal long-distance measurement effect can be obtained; the beam diameter can be changed by the beam expander for different optical instruments; the use of the beam expander with the spatial filter can make the asymmetric beam distribution Become a symmetrical distribution, and make the light energy distribution more uniform.



Protective lens

Laser protective lens is one of the necessary accessories during the use of laser welding equipment. The main function of the protective lens is to block debris from splashing and prevent the splash from damaging the lens or the operator. The high-damage anti-reflection coating on both sides can also reduce reflection. The general replacement period of the protective lens is 3 months or depends on the actual situation.

Reflective lens

In a laser system, there are generally only one or two transmissive optical elements, which are usually used as the output mirror of the laser cavity and the focusing lens at the end. In some other laser systems, there may be five or more reflective lenses. Reflective lenses are used as tail mirrors and refracting mirrors to control beam steering in laser cavity and beam delivery systems.

Copper mouth

The copper nozzle can assist the rapid ejection of gas, which can effectively prevent the melting stains and other debris from rebounding, thereby protecting the focusing lens. At the same time, the copper nozzle can also 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 according to the thickness of the cut material. The replacement cycle is generally about two months.



The components and quality of laser equipment are directly related to the application efficiency of the entire laser system. Only the laser accessories manufacturers who choose the brand can achieve high integration and high application efficiency in the accessories, and the technical quality can be effectively guaranteed.CARMAN HAAS Laser Technology (Suzhou) Co., Ltd is a national high-tech enterprise integrating research and development, production, inspection, application testing and sales of laser optical components and optical systems.
