Title (EN) DENTAL MILLING MACHINE
(FR) FRAISEUSE DENTAIRE
(DE) DENTALFRÄSMASCHINE
Abstract:
(EN) The invention relates to a dental milling machine comprising a workpiece holder (2) and a changer arm (10), characterised in that the changer arm (10) has a substantially U-shaped gripping attachment (12) and in that a tool (14) of the dental milling machine (1) has a tool fixation element (16). The tool fixation element has grooves (18) or holding projections at two mutually opposed positions which face away from each other, over which grooves or holding projections the U-shaped gripping attachment (12) of the changer arm (10) can engage, wherein parts of the U-shaped gripping attachment (12), more particularly the side flanks (12a, 12b) of the U-shaped gripping attachment (12), make contact with the grooves (18) or holding projections of the tool fixation element (16) under preload.
(FR) La présente invention concerne une fraiseuse dentaire munie d'un porte-pièce (2) et d'un bras changeur (10) qui est caractérisée en ce que le bras changeur (10) présente un accessoire de préhension (12) sensiblement en forme de U et en ce qu'un instrument (14) de la fraiseuse dentaire (1) présente un élément de fixation d'instrument (16). L'élément de fixation d'instrument présente, en deux endroits disposés de manière opposée et distants l'un de l'autre, des rainures (18) ou des projections de retenue sur lesquelles peuvent empiéter l'accessoire de préhension (12) en forme de U du bras changeur (10), des pièces de l'accessoire de préhension (12) en forme de U, en particulier les flancs latéraux (12a, 12b) de l'accessoire de préhension (12) en forme de U, étant ajustées en tension sur les rainures (18) ou les projections de retenue de l'élément de fixation d'instrument (16).
(DE) Eine Dentalfräsmaschine mit einem Werkstückhalter (2) und einem Wechselarm (10) ist dadurch gekennzeichnet, dass der Wechselarm (10) einen im Wesentlichen U-förmigen Greifaufsatz (12) aufweist und dass ein Werkzeug (14) der Dentalfräsmaschine (1) ein Werkzeug-Fixierelement (16) aufweist. Das Werkzeug-Fixierelement weist an zwei einander gegenüberliegenden und voneinander weg weisenden Stellen Nuten (18) oder Haltevorsprünge auf, die von dem U-förmigen Greifaufsatz (12) des Wechselarmes (10) übergreifbar sind, wobei Teile des U-förmigen Gefräsaufsatzes (12), insbesondere Seitenflanken (12a, 12b) des U-förmigen Greifaufsatzes (12) unter Vorspannung an den Nuten (18) oder Haltevorsprüngen des Werkzeug-Fixierelements (16) anliegen.
