In order to improve said machine tool in such a way that multiple complex machining processes can be carried out in an optimal fashion, the support head (20) is mounted on a support arm (24) so as to be pivotable about a first swiveling axis (26) while said support arm (24) is mounted so as to be pivotable relative to a support base (30) about a second swiveling axis (32) that is located parallel to and at a distance from the first swiveling axis (26). Furthermore, the support base (30) can be moved relative to the machine frame (10) by means of at least one controlled axis of movement (X, Y, Z).

Abrégé

In order, in a multi-spindle lathe, comprising a lathe frame, a spindle drum, which is mounted on the lathe frame such that it can rotate about a spindle drum axis and has an end face facing a working space, a multiplicity of workpiece spindles, which are mounted in the spindle drum in such a manner that they can rotate about spindle axes and have workpiece-accommodating means, which are disposed so as to face the working space and into which workpieces which are to be machined in the working space can be inserted, also to ensure that the points in time and time durations for handling workpieces involve the minimum possible loss of machining time, it is proposed that there is a pivot-arm handling device, the foot of which is disposed on an opposite side of the working space from the end face of the spindle drum and which is formed in such a way that it can be used to insert workpieces into the workpiece-accommodating means of the workpiece spindles or to remove them therefrom, through the working space.
