Patent ID: 8376921

Claim:
A machine tool comprising a machine frame ( 10 , 20 ), a tool spindle ( 30 ) that can be driven so as to rotate, a workpiece clamping mechanism ( 12 ) and a magazine, wherein the tool spindle ( 30 ) and the workpiece clamping mechanism ( 12 ) can be moved relative to one another on a linear X-axis in a controlled manner, and wherein the tool spindle ( 30 ) can be moved in a controlled manner in relation to machine frame ( 10 , 20 ) on Y- and Z-axes which are perpendicular to the X-axis and to each other and can be pivoted in a controlled manner around a C-axis parallel to the Z-axis, characterized in that the magazine has at least one magazine wheel ( 42 , 66 ) which can be positioned rotating around a rotational axis parallel to the Z-axis, that the magazine wheel ( 42 , 66 ) has recesses ( 58 , 76 ) for tools ( 60 ) and/or workpieces ( 62 , 64 , 78 ) arranged distributed in its circumferential direction, that a workpiece gripper ( 34 ), which can be moved in common with the tool spindle ( 30 ), is assigned to the tool spindle ( 30 ), and that the tool spindle ( 30 ) can travel with the workpiece gripper ( 34 ) to the magazine wheel ( 42 , 66 ) on the Y, Z and C-axes and can be aligned in relation to the recesses ( 58 , 76 ) so that either a tool ( 60 ) can be exchanged between the tool spindle ( 30 ) and a recess ( 58 ) of the magazine wheel ( 42 , 66 ) or a workpiece ( 62 , 64 , 78 ) can be exchanged between the workpiece gripper ( 34 ) and a recess ( 58 , 76 ) of the magazine wheel ( 42 , 66 ), wherein the movements on the X, Y, Z and C axes effect a transfer of the workpiece ( 16 , 62 , 64 , 78 ) between the workpiece gripper ( 34 ) and the workpiece clamping mechanism ( 12 ).
