Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Bestrahlen eines Werkstücks mit Strahlmitteln (3, 4) in festem Aggregatzustand, wobei die Strahlmittel in einer Strahlanlage (1) in einen Gasstrom (2) eindosiert, mit dem Gasstrom zu einer Strahlvorrichtung (5) gefördert und auf das zu bearbeitende Werkstück gestrahlt werden.The invention relates to a method and an apparatus for irradiating a Workpiece with blasting media (3, 4) in a solid state, the blasting media in a jet system (1) metered into a gas stream (2), with the gas stream to a Blasting device (5) promoted and blasted on the workpiece to be machined.

Erfindungsgemäß umfassen die Strahlmittel (3, 4) sowohl bei Normalbedingungen in gasförmigem oder flüssigem Aggregatzustand vorliegende erste Strahlmittel (3) als auch bei Normalbedingungen in festem Aggregatzustand vorliegende zweite Strahlmittel (4).According to the invention, the blasting media (3, 4) comprise both in normal conditions gaseous or liquid state of aggregation first blasting agent (3) as second blasting media also present under normal conditions in a solid state (4).

Als erstes Strahlmittel (3) eignet sich Trockeneis (CO2), welches bei Normalbedingungen in gasförmigem Aggregatzustand vorliegt. Als bei Normalbedingungen in festem Aggregatzustand vorliegendes zweites Strahlmittel (4) kann beispielsweise Sand verwendet werden.

Figure 00000001
The first blasting agent (3) is dry ice (CO 2 ), which is in gaseous state under normal conditions. Sand, for example, can be used as the second blasting agent (4) which is present in a solid state under normal conditions.
