Boring and deburring head and boring and deburring tool capable of being fastened therein, and method for boring and deburring a workpiece

Claim 1

A boring and deburring head for fastening a boring and deburring tool, comprising: a drive element that can be coupled with a rotationally driven bore spindle or the like, said drive element defining a longitudinal axis of rotation and including a cup-shaped area defining an inner cylindrical face; a clamping device for clamping a boring and deburring tool, said clamping device defining a longitudinal axis of rotation, and being connected to the drive element to be pivotable relative thereto and such that relative rotation between the drive element and the clamping element is prevented, said clamping device including a clamping cone having a rear area defining a spherical circumferential face which is inserted, without substantial radial play, into the cup-shaped area of the drive element and in engagement with the inner cylindrical face of the cup-shaped area, as a result of which shifting of the clamping device relative to the drive element with respect to an initial position of the clamping device is permitted such that the axis of rotation of the clamping device is shifted relative to the axis of rotation of the drive element; shifting means connected to the clamping device for effecting shifting of the clamping device from its initial position to a shifted position; and restoring means connected to the clamping device for returning the clamping device to its initial position from its shifted position.
