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.
Claims19
A tool for machining a recess in the bore of a workpiece, said tool comprising
- a holding arm having a longitudinal axis and a dimension transverse to said longitudinal axis, and
- a tool wheel mounted for rotation on said holding arm about a bearing axis which is transverse to and offset from the longitudinal axis of the holding arm, said tool wheel comprising a rotationally symmetric hollow carrier which, with said holding arm, forms a housing for accommodating a bearing arrangement and a drive for the tool wheel, said tool wheel further comprising a machining body arranged on the outer circumference of said carrier and projecting beyond the transverse dimension of the holding arm on only one side of the holding arm, whereby
- said tool may be used to machine a recess in the bore of a workpiece, said recess having a depth corresponding to the projection of said machining body beyond said holding arm.
