Abstract:
1. Device for machining work pieces that rotate around a work piece axis (Z), with a tool that can be rotationally driven around a tool axis, a clamping device ( 9 , 9 ′) on which a work piece can be clamped, said clamping device clamping a workpiece prior to machining at a first position and releasing said work piece subsequent to machining in said first position ( 9 , 9 ′), and a transfer device ( 25 ) which can transfer the clamping device ( 9 , 9 ′) from the first position into a spatially separated second position where it can be rotationally driven around the work piece axis (Z) during machining by a work piece spindle ( 1 ) that is connected to the clamping device ( 9 ), wherein the connection between the clamping device ( 9 , 9 ′) and the work piece spindle ( 1 ) has a first connecting segment ( 7 ) that is permanently fixed at the work piece spindle ( 1 ) and a complementary second connecting segment ( 8 ) that is permanently fixed at the clamping device ( 9 , 9 ′), which can be separated and reconnected by a relative motion between the first connecting segment ( 7 ) and the second connecting segment ( 8 ).
