ABSTRACT:
A laser beam is applied to a workpiece by means of a spring-loaded metal nozzle which engages the workpiece. An aperture in the workpiece end of the nozzle accurately defines the size of the hole formed in the workpiece by the laser beam. A chamber located within the lower end of the nozzle is continuously evacuated by a vacuum pump to remove the drilling debris. Adjustment of the degree of vacuum within the nozzle adjusts the bearing pressure of the nozzle on the workpiece.
