Abstract
The invention relates to a gas guide (11, 11a, 11b, 11c) for a laser cutting head (10) having a nozzle (19), having a central flow axis (S), comprising a base part having a pressure chamber (24) concentrically surrounding the flow axis (S), configured for the reception of a gas flow (20a, 20b, 20c), wherein the base part has at least four gas conduits (26a, 26b, 26c), which extend from the pressure chamber (24) in the direction of the flow axis (S), and wherein the cross-sections of the pressure chamber (24) and the gas conduits (26a, 26b, 26c) are dimensioned such that the gas has a maximum flow rate when it exits the gas conduits.
