Abstract: A grinding machine includes a machine bed on which a workpiece spindle with a workpiece holder and a tool spindle with a tool holder are arranged. A workpiece held in the workpiece spindle, relative to a tool held in the tool holder, is displaceable along an X-axis running in a first direction parallel to the surface of the machine bed, is displaceable along a Y-axis, running in a second direction parallel to the surface of the machine bed, is displaceable along a Z-axis running perpendicular to the surface of the machine bed, is rotatable about an A-axis running parallel to the surface of the machine bed, and is rotatable about a C-axis running perpendicular to the surface of the machine bed. The tool spindle is completely kinematically separated from the workpiece spindle. Movements along the X-axis, about the A-axis and about the C-axis being carried out by the workpiece spindle.

Abstract: A machine tool comprising a tool spindle and a workpiece clamping mechanism moveable relative to one another on a linear X-axis in a controlled manner, wherein the tool spindle can be moved in a controlled manner in relation to a machine frame 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, and wherein a workpiece gripper, which can be moved in common with the tool spindle, is assigned to the tool spindle, and that the tool spindle can travel with the workpiece gripper to a magazine wheel on the Y, Z and C-axes and can be aligned with recesses on the magazine wheel, movement on the X, Y, Z and C-axes effecting transfer of a workpiece between the workpiece gripper and the workpiece clamping mechanism.

Abstract: 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) in 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, wherein 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, wherein a workpiece gripper (34), which can be moved in common with the tool spindle (30), is assigned to the tool spindle (30), and wherein the tool s
