Laser cutting machines are roughly divided into bed systems, laser optical path systems, and transmission control systems. Laser cutting is a relatively advanced machine for thermal cutting and is also equipped with an automatic environmental protection smoke extraction system. Ensure that there are no fire hazards and harmful exhaust gases generated by cutting during the production process, which will harm workers and the environment. The bed bed system mainly plays a role in stabilizing the machine. The equipment is divided into two designs: non-constant optical path and constant optical path. The non-constant optical path has the advantages of low cost and simple structure, and can be used for cutting products with low precision requirements. The constant optical path design route ensures the optimal distance from the laser tube to the laser head. The structure is relatively complex, which is of great help to cutting accuracy and efficiency. The most accurate laser cutting machine sold on the market in the traditional system is the lead screw drive design. High-quality machines have very strict requirements on the material and precision of accessories.
