LASER MACHINING HEAD HAVING A CROSS-JET NOZZLE CLOSE TO THE WORKPIECE |
摘要 |
A laser machining head includes a focusing optical unit for focusing a laser beam in a direction of a machining zone of a workpiece and includes a cross-jet nozzle for producing a cross flow that passes through the focused laser beam transversely (e.g., at a right angle to) a beam axis of the focused laser beam. The distance of the cross-jet nozzle from the workpiece is less than 20 mm (e.g., between 8 mm and 12 mm). A nozzle body having a bottom opening that faces downward toward the workpiece is provided laterally adjacent to the focused laser beam. A protective gas flows out of the bottom opening, which is arranged below the cross-jet nozzle in order to entrain the protective gas flowing between the nozzle body and the workpiece due to the cross flow of the cross-jet nozzle so that the protective gas flows over the machining zone. |
