Beschreibung
Zusammenfassung:	The arrangement has a tool spindle (3) mounted in a bearing neck (1) and rotatably drivable around a rotational axis (2). An extraction hood (4) encloses the tool spindle, where the extraction hood is positively fixed at the bearing neck in an exchangeable manner by a quick-release fastener and does not contact the tool spindle. The quick-release fastener is formed by a bayonet lock (5). A magnet (6) i.e. permanent magnet, is provided for axially securing the extraction hood with respect to the bearing neck. The extraction hood includes a radial wall (12) with a middle spindle opening (13). Die Erfindung betrifft eine insbesondere stationäre Maschinenanordnung zum zerspanenden Bearbeiten von Werkstücken. Die Maschinenanordnung umfasst einen Lagerhals (1), eine im Lagerhals (1) um eine Drehachse (2) drehend antreibbar gelagerte Werkzeugspindel (3) und eine die Werkzeugspindel (3) umgreifende Absaughaube (4). Die Absaughaube (4) ist am Lagerhals (1) auswechselbar und ohne Kontakt mit der Werkzeugspindel (3) befestigt.
