Abstract

A machine tool for the cutting machining of workpieces, in particular of metallic workpieces, has a first and a second tool spindle for receiving a first and a second machining tool, and it has a first and a second workpiece carrier for receiving a first workpiece and a second workpiece. The first tool spindle is movable relative to the first and to the second workpiece carrier in order to selectively machine the first or the second workpiece. Moreover, the first workpiece are movable relative to one another in order to transfer a workpiece from one workpiece carrier to the other workpiece carrier. The second tool spindle is movable relative to the second workpiece carrier in order to machine the second workpiece.

Dependent claims

A machine tool for cutting machining of workpieces, comprising

a first tool spindle for receiving a first machining tool,
a second tool spindle for receiving a second machining tool,
a first workpiece carrier for receiving a first workpiece, and
a second workpiece carrier for receiving a second workpiece,
with the first tool spindle being movable relative to the first workpiece carrier and relative to the second workpiece carrier in order to selectively machine the first workpiece or the second workpiece with the first machining tool,
with the second tool spindle being movable relative to the second workpiece carrier in order to machine the second workpiece, and
with the first and the second workpiece carriers being movable relative to one another via pivoting of at least one of the workpiece carriers about an axis that is substantially perpendicular to a rotation axis of a workpiece held by at least one of the workpiece carriers, in order to transfer a workpiece from one workpiece carrier to the other workpiece carrier.
