Abstract: The tool comprises a tool wheel (5) which is mounted on a holding arm (4) and has a tool-wheel parent body (6) having a machining body (7) arranged at the outer margin. In one embodiment variant, this machining body is designed as an abrasive body. A base body for accommodating the bearing arrangement is designed in one piece with the holding arm (4), which also has the supply lines (8) for the hydrodynamic bearing arrangement and the hydraulic drive. A tool-centering interface (11) permits the presetting of the tools outside the machine tool.
