Abstract
In the cutting of workpieces by means of a laser beam, gas is blown onto workpiece at high speed together with the beam. It is proposed to design gas outflow nozzles (60) in such a way that they are formed as grooves in the conical end face (49) of a nozzle insert (47) and, on the other hand, are formed by a nozzle cap (48) which has a portion of such a matching conical shape that the grooves are covered. It is also proposed to provide a unifying chamber (formed by an attached cap), in which the gas jets are unified, so that they then flow out, together with the laser beam, as a single gas jet.
