Abstract

Die Spannvorrichtung hat eine drehbar angetriebene Spindel (2), auf der eine hydraulisch aufweitbare Spannbuchse (5) sitzt, mit der das Werkzeug (32, 33) gespannt werden kann. Die Spindel (2) hat eine Hydraulikmedium-Kammer (6), die mit einer die Spindel (2) durchsetzenden, das Hydraulikmedium zuführenden Bohrung (9) verbunden ist. Sie ist durch eine Spannschraube (11) geschlossen, die in eine Druckentlastungs­ stellung zurückschraubbar ist, wenn das Werkzeug von der Spannbuchse abgeschoben bzw. auf diese geschoben werden soll. Zusätzlich zur radialen Spannung und Zentrierung wird das Werkzeug durch ein Axialspannglied (19) axial fixiert und gespannt, das axial verstellbar angeordnet und mit dem Werk­ zeug (32, 33) in Axialrichtung formschlüssig verbunden ist.
