Abstract

The invention relates to a machine tool having a frame (1) and two workpiece spindles (5, 6) and a tool support (9) associated with both tool spindles (5, 6) and comprising tools (13). The workpiece spindle (5) can be moved with respect to the machine frame (1) in a first sub-region (17) and the workpiece spindle (6) can be moved in a second sub-region (18) on the guide rails (2) in at least one direction. A separating gap (16) is provided between the first and the second sub-regions (17, 18).

Description

Doppelspindlige Werkzeugmaschine  Double spindle machine tool

Die Erfindung betrifft eine Werkzeugmaschine mit zwei Werkstückspindeln und mindestens einem diesen zugeordneten Werkzeugträger nach dem Oberbegriff des Patentanspruchs 1. An mehrspindligen Werkzeugmaschinen kann die Bearbeitung mit niedrigen Drehzahlen und vor allem bei unterbrochenem Schnitt zu gegenseitig beeinflussten Arbeitsergebnissen führen. Die DE 197 53 898 A1 schlägt daher eine Vertikal-Drehmaschine mit zwei Spindeln vor, die auf getrennten schwingungsisolierten Maschinenbetten gelagert sind. Um  The invention relates to a machine tool having two workpiece spindles and at least one associated tool carrier according to the preamble of claim 1. On multi-spindle machine tools machining at low speeds and especially at interrupted cut can lead to mutually influenced work results. DE 197 53 898 A1 therefore proposes a vertical lathe with two spindles, which are mounted on separate vibration-insulated machine beds. Around

Werkstücke von einem zum anderen Spindelkasten zu transportieren sind die To transport workpieces from one to the other headstock are the

Maschinenbetten zumindest im Bereich der Führungsbahnen verbindbar. Das Ausrichten, bzw. Justieren der beiden Maschinenbetten zueinander ist recht aufwändig, besonders dann, wenn beiden Spindelkästen ein einziger Werkzeugträger zugeordnet ist. Es ist die Aufgabe der vorliegenden Erfindung eine mehrspindlige Werkzeugmaschine mit optimierter Schwingungsisolation aufzuzeigen. Gelöst wird diese Aufgabe mit einer Machine beds connectable at least in the area of the guideways. The alignment, or adjustment of the two machine beds to each other is quite complex, especially if two spindle boxes a single tool carrier is assigned. It is the object of the present invention to show a multi-spindle machine tool with optimized vibration isolation. This task is solved with a

Im Folgenden wird die Erfindung an Hand eine Ausführungsbeispiels näher erläutert. Fig. 1 zeigt eine erfindungsgemäße Werkzeugmaschine in schematischer Darstellung. The invention will be explained in more detail below with reference to an exemplary embodiment. Fig. 1 shows a machine tool according to the invention in a schematic representation.

Das Maschinengestell 1 ist in der Vorderansicht T-förmig gestaltet. Der schlanke untere Teil ist dabei säulenförmig ausgebildet und der obere Teil verbreitert sich zu den Seiten hin und bildet den Querbalken des„T". Der Querbalken wird etwa in der Mitte durch eine Trennfuge 16 in zwei Teilbereiche 17, 18 unterteilt. Die Trennfuge 16 verhindert, dass die bei der Werkstückbearbeitung auftretenden Kräfte das Arbeitsergebnis, z.B. die Oberflächenqualität, an der jeweils anderen Werkstückspindel beeinflussen. An der Vorderseite des  The machine frame 1 is designed T-shaped in the front view. The slender lower part is in this case in the shape of a column and the upper part widens to the sides and forms the transverse bar of the "T." The transverse bar is divided approximately in the middle by a parting line 16 into two partial areas 17, 18. The parting line 16 prevents in that the forces occurring during workpiece machining influence the work result, eg the surface quality, on the respective other workpiece spindle
