Abstract
A tool (2) for machining workpieces, comprising a carrier (4) rotating in an axial direction (A) during operation, and further comprising multiple cutting segments (6), which are fastened to the carrier (4) in a radial direction (R), characterized in that at least one hydraulic clamping unit (21) is attached to the carrier (4) for clamping at least one of the cutting segments (6) to the carrier (4).
Claims18
A tool for machining workpieces, comprising a carrier rotating in an axial direction during operation, and further comprising multiple cutting segments, which are fastened to the carrier in a radial direction,
- wherein at least one hydraulic clamping unit is attached to the carrier for clamping at least one of the cutting segments to the carrier;
- and
- wherein the cutting segments can be reversibly fixed, by clamping, to the carrier jointly by a clamping ring.
A tool for machining workpieces, comprising a carrier rotating in an axial direction during operation, and further comprising multiple cutting segments, which are fastened to the carrier in a radial direction,
- wherein at least one hydraulic clamping unit is attached to the carrier for clamping at least one of the cutting segments to the carrier;
- and
- wherein a clamping element, which is used to generate hydraulic pressure by means of the hydraulic clamping unit and, for this purpose, can be toggled between a clamping position and a release position, so as to clamp and release the cutting segments;
- and
- wherein the at least one hydraulic clamping unit comprises multiple hydraulic clamping units which can be actuated jointly by means of the clamping element.
A tool for machining workpieces, comprising a carrier rotating in an axial direction during operation, and further comprising multiple cutting segments, which are fastened to the carrier in a radial direction,
- wherein at least one hydraulic clamping unit is attached to the carrier for clamping at least one of the cutting segments to the carrier;
- and
- wherein a clamping element, which is used to generate hydraulic pressure by means of the hydraulic clamping unit and, for this purpose, can be toggled between a clamping position and a release position, so as to clamp and release the cutting segments;
- and
- wherein the clamping element is adapted to be toggled between the clamping position and the release position by at least one of the following (a) or (b):
- (a) the clamping element is formed as a rotating annulus, which can be toggled between the clamping position and the release position by a rotation;
- or
- (b) in in order to toggle between the clamping position and the release position, at least one eccentric actuating element is attached on the clamping element so as to actuate the hydraulic clamping unit when toggling into the clamping position.
