Abstract
A tool for machining workpieces, having a parent body which can be expanded at least zonally, having at least one geometrically defined cutting edge projecting beyond a circumferential surface of the tool, and having a setting device influencing the radial distance of the cutting edge from the center axis of the tool. The setting device has a setting element, and an adjusting device which sets the degree of bending of the setting element. The setting element is inserted into the parent body of the tool in such a way that, when the bending of the setting element is varied, the radial distance of the cutting edge is varied.
Claims16
A tool for machining workpieces, having a parent body, having at least one cutting edge projecting beyond a circumferential surface of the parent body, and having a setting device that sets a radial distance of the at least one cutting edge from a center axis of the parent body, wherein the setting device has a setting element, and an adjusting device which can be actuated to vary bending of the setting element, and wherein the setting element is disposed in the parent body of the tool in such a way that, when the bending of the setting element is varied from an initial position, the radial distance of said at least one cutting edge is varied from an initial position, wherein the adjusting device comprises an adjusting screw.
The tool as claimed in 4, wherein the abutment comprises a welded connection between the setting element and the parent body.
The tool as claimed in 7, wherein the bending of the setting element sets the radial distance of all of the plurality of cutting edges of the tool.
The tool as claimed in 3, wherein said setting element is initially curved convexly away from said parent body of said tool.
The tool as claimed in 3, wherein said setting element is initially curved concavely toward said parent body of said tool.
A tool for machining workpieces, having a parent body, having at least one cutting edge projecting beyond a circumferential surface of the parent body, and having a setting device that sets a radial distance of the at least one cutting edge from a center axis of the parent body;
- wherein the setting device has a setting element, and an adjusting device which can be actuated to vary bending of the setting element;
- wherein the setting element is disposed in the parent body of the tool in such a way that, when the bending of the setting element is varied from an initial position, the radial distance of said at least one cutting edge is varied from an initial position;
- and
- wherein the setting element is planar in said initial position.
A tool for machining workpieces, having a parent body, having at least one cutting edge projecting beyond a circumferential surface of the parent body, and having a setting device that sets a radial distance of the at least one cutting edge from a center axis of the parent body;
- wherein the setting device has a setting element, and an adjusting device which can be actuated to vary bending of the setting element;
- wherein the setting element is disposed in the parent body of the tool in such a way that, when the bending of the setting element is varied from an initial position, the radial distance of said at least one cutting edge is varied from an initial position;
- wherein the setting element is curved in said initial position;
- and
- wherein said setting element is initially curved concavely toward said parent body of said tool.
