The nozzle often used for the 6 kW laser is a conical nozzle.There are three main forms of nozzles: parallel, collected and cone forms, 6 kW laser nozzle often used the most is the conical nozzle, the conical nozzle has good cutting quality, high cutting precision advantages. For nitrogen cutting stainless steel, and then precision, surface requirements are relatively high fine cutting.

1. laser cutting nozzle sp high-speed single and double layer, the use of T3 grade copper, with excellent electrical and thermal conductivity, nozzle cutting speed, cutting surface finish is high, long life, one-time processing molding, the inner wall is smooth, oxidation treatment area.2. laser cutting nozzle se is the use of conventional single-layer high-speed double-layer pressurization, different from ordinary copper brass, the use of T3 imported copper, high induction, excellent electrical and thermal conductivity, CNC milling machine, drilling, grinding, tapping, high precision, small error variety guarantee.

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.

Because of its high gas flow rate, the double-layer nozzle is generally used for high-speed cutting, and the single-layer laser nozzle is used for melting cutting, which uses nitrogen as an auxiliary gas.The nozzle is a very common loss on the laser cutting machine, but also a very important part of the laser cutting, it is located at the bottom of the laser head, very close to the workpiece, so it plays a very key role in the cutting process.
