Title
(DE) WERKZEUGMASCHINE ZUM BEARBEITEN VON LÄNGLICHEN WERKSTÜCKEN
(EN) MACHINE TOOL FOR MACHINING ELONGATED WORKPIECES
(FR) MACHINE-OUTIL POUR L'USINAGE DE PIECES ALLONGEES
Abstract
(DE) Die Maschine hat mindestens eine um eine erste Rotationsachse (A) antreibbare Spannvorrichtung (22) für ein Werkstück (23) und mindestens eine um eine zweite Rotationsachse (C) antreibbare Werkzeugspindel (18). Auf einer Führung (4) sind drei Schlitten (5, 6, 7) durch Antriebe unabhängig voneinander verschiebbar und mittels Lenkern (11, 12, 13) mit einer die Werkzeugspindel tragenden Einheit (17) verbunden. Durch Verschieben der Schlitten entlang der Führung ist das Werkzeug (19) entlang einer X-Achse und einer Z-Achse verschiebbar und zudem in einem Bereich schwenkbar. Eine solche Maschine weist eine gegenüber bekannten derartigen Maschinen reduzierte Anzahl von Antrieben und insbesondere Führungen auf und kann leicht modular gestaltet werden. Darüber hinaus sind bei dieser Maschine die bewegten Massen gegenüber dem vorbekannten Stand der Technik gering, was die Dynamik der Maschine verbessert.
(EN) The inventive machine has at least one workpiece (23) clamping device (22) which can be driven around a first axis of rotation (A), and at least one tool spindle (18) which can be driven around a second axis of rotation (C). Three slides (5, 6, 7) can be moved independently of each other on a slide guide (4) by means of drive mechanisms, and are connected by guide rods (11, 12, 13) to a unit (17) which supports the tool spindle. As the slide is moved along the slide guide, so the workpiece (19) can be moved along an X-axis and a Z-axis, and turned in a certain area. The inventive machine has fewer drive mechanisms and especially slide guides than known machines of the same type and is easy to construct modularly. The masses which are moved in the inventive machine are also less than in known machines and the dynamics of the inventive machine are better as a result.
(FR) L'invention concerne une machine qui comporte au moins un dispositif de serrage (22) pour une pièce (23), tournant autour d'un premier axe de rotation (A), et au moins une broche d'outil (18) tournant autour d'un deuxième axe de rotation (C). Trois chariots (5, 6, 7) peuvent être déplacés, indépendamment les uns des autres, sur un guidage (4) par des entraînements et peuvent être reliés au moyen de guides (11, 12, 13) à une unité (17) portant la broche d'outil. L'outil (19) peut être déplacé le long d'un axe X et d'un axe Z et également être incliné dans une zone, par déplacement des chariots le long du guidage. La machine selon l'invention présente, par rapport aux machines comparables connues, un nombre réduit d'entraînements et en particulier de guidages; une conception modulaire est également aisée. En outre, dans cette machine, les masses déplacées sont faibles par rapport à l'état connu de la technique, ce qui améliore la dynamique de la machine.
