Abstract
The machine tool is provided for working ring-shaped workpieces (1), in particular one-piece turbine wheels, so-called 'bladed rings'. It has a rotatable chucking device (2) for a workpiece (1). Said chucking device is mounted on a carrying part (4), which in turn is supported by a supporting component (5). In order to keep the dimension (14) of the length by which the carrying part (4) projects beyond the workpiece (1) on the side facing the supporting component (5), as low as possible, the carrying part (4) protrudes into the chucking device (2) to such an extent that it projects at least through the boundary surface (7) of the workpiece (1) facing the supporting component (5). A saving of space is achieved in this way and, therefore, enhanced accessibility is obtained for the tool to the side of the workpiece (1) facing the supporting component (5).
