ABSTRACT:
A machine tool comprises a turntable that has a table plate, pivotable about a rotation axis with respect to a machine frame, onto the upper side of which lead lines, coming from beneath the table plate, that are connected to stationary supply connections. The lines are attached to the table plate from below, by means of downward-pointing connector pieces that are joined nonrotatably to the table plate in its center region, in such a way that they hang freely downward.
