Choosing the Right Nozzle for Your Fiber Laser Cutting Machine The nozzle of the laser cutting machine can assist the rapid ejection of the gas, and it can control the area and size of the gas diffusion, thus affecting the cutting quality of the laser cutting machine. When cutting metal, how to choose a nozzle fiber laser cutting machine in order to obtain higher cutting quality? 1. Nozzle size selection The user selects the nozzle size according to the thickness of the cut sheet metal. Generally, when the laser cutting machine is used to cut thin plates less than 3mm, it is recommended to use a nozzle with a diameter of 1.5mm, and a nozzle with a diameter of 2mm is recommended for those with a thickness greater than 3mm. For cutting sheet metal over 10mm, a nozzle with a diameter of 3mm or more is generally selected. 2. Selection of different power nozzles (1) Laser power≤6000w For cutting carbon steel, the diameter of the nozzle is generally double-layer s 1.0-5.0E; For cutting stainless steel, the diameter of the nozzle is generally S1.0-5.0E for a single layer.
(2) Laser power≥6000w Cutting carbon steel: 10-25mm carbon steel smooth cutting, the diameter of the cutting nozzle is generally double-layer high-speed E-type S1.2 ~ 1.8E single-layer fan diameter is generally d 1.2-1.8; Cutting stainless steel: The diameter of the nozzle is generally S1.0-5.0E for a single layer.
