The laser nozzle is one of the most important parts of a fiber laser cutting machine. It is installed at the at the front end of the laser cutting head, which helps to control the auxiliary gas and protect the focus lens. Laser power and high-pressure airflow are emitted through the nozzle, which is related to the cutting quality.
Single layer nozzles used in laser equipment are mainly used for cutting stainless steel and aluminium plates with gas nitrogen. Double layer nozzles are mainly used for cutting carbon steel with gas oxygen. Nozzles are commonly made of two materials which are copper and brass.
