20210107065 · 2021-04-15 ·

A tool drive unit for a turning device for machining workpieces has a tool holder driven in a displaceable manner along an infeed direction by a first linear motor and driven in a pendular/displaceable manner in a direction transverse to the infeed direction by a second linear motor. Both linear motors have a moving coil/piezo element. The turning device has a main infeed drive, which produces a primary infeed movement of a turning tool in an infeed direction, and has a main transverse drive which produces a primary transverse movement in a transverse direction transversely to the infeed direction. The turning device has a secondary transverse drive whose movements are oriented in the same direction as the main transverse drive, wherein the turning tool and the axis of rotation can be moved towards one another and away from one another by the superimposition of primary and secondary transverse movements.
