In the process of producing the nozzle of the laser cutting machine, different models will be represented by different English letters. Where d represents the general horizontal distance and s represents the oblique distance.
Laser nozzles are divided into single and double layers. Single-layer laser nozzle is used for melting cutting, that is, nitrogen as auxiliary gas, cutting stainless steel and aluminum plate with single-layer laser nozzle. Double-layer laser nozzles are generally used for oxidation cutting, that is, using oxygen as an auxiliary gas to cut carbon steel with double-layer laser nozzles.
