Laser Cutting Machine Cutting Head Nozzle

The laser cutting head is an important part of the laser cutting machine. Its main function is to focus the laser beam and guide it to the workpiece for cutting.
Nozzle
The selection of the nozzle form and nozzle size has a great influence on the cutting quality. There are three main types of nozzles: parallel, convergent and cone. As shown in the overview diagram. However, some foreign institutions have applied the knowledge of gas dynamics to study the convergent-divergent nozzle. This type of nozzle has good cutting characteristics when used for cutting. However, due to the complex inner cavity of the nozzle, the processing process and fine type are limited, making it impossible to put it into industrial production.
