Abstract

A laser machine for machining workpieces has a workpiece support that forms a support main plane and is permeable to air perpendicularly to the support main plane. Supply air is directed to an upper side of the workpiece support. Air that is contaminated due to machining is discharged as exhaust air from the upper side of the workpiece support through the workpiece support to the bottom side of the workpiece support. In order to generate a laminar supply air flow which is perpendicular to the upper side of the workpiece support, the flow cross section of the supply air channel is divided into partial cross sections by partial cross sectional walls.
