<p>To cool the nozzle on a laser machining tool, an additional cooling or working gas is directed outside the nozzle (1) up to the nozzle tip (7), where it escapes into the atmosphere. For this purpose, a concentric annular chamber is formed around the outside of the nozzle (1). Also arranged in the annular chamber is a sensor device (8), which is thus likewise cooled. <IMAGE></p> |
