Abstract
A device for processing a workpiece which, for this purpose, is fixed inside a working space (or enclosure) in a machining center and is processed with the aid of a tool. To remove processing residues, a gas stream is made to flow through working space, which is formed, for this purpose, like a nozzle. So as to improve further the removal of undesired processing residues from working space, without at the same time increasing the performance of the devices generating air stream, the working space is widened after the narrowest cross sectional area, in the flow direction of gas stream, similar to a Laval nozzle, machining center being situated in the region of the greatest flow speed. Because of this arrangement, in addition, an undesired limitation of working space available for machining center may be avoided.
