Patent number: 10967434Abstract: A boring head (1) with an electronic unit (20) integrated in the boring head (1) is provided, the electronic unit (20) comprising a control unit (60), a display (30) and a compartment (26) for a power source (41). The display (30) is connected to the control unit (60) and serves to display information concerning the status of the boring head (1) to a user. The compartment (26) serves to accommodate a power source (41) to supply the control unit (60) and the display (30) with electric power. The electronic unit (20) as a whole is designed as a compact subassembly of the boring head (1).Type: GrantFiled: August 10, 2017Date of Patent: April 6, 2021Inventors: Jose Maria Fenollosa, Ralph Stadelmann

Patent number: 8747034Abstract: The boring head has a tool body (2, 38), to which two cutter holders (3, 4; 22, 23) arranged offset from one another by 180° are fastened. The cutter holders (3, 4; 22, 23) are mounted on a clamping surface (11, 26) in a slidable manner for radially adjusting the cutters (5). The clamping surface (11, 26) has a first partial clamping surface (11a, 26a) for the one cutter holder (3, 4; 22, 23) and a second partial clamping surface (11b, 26b) for the other cutter holder (3, 4; 22, 23). These two partial clamping surfaces (11a, 11b; 26a, 26b) are offset in the axial direction by a certain extent. The two cutter holders (3, 4; 22, 23) have different heights with respect to the cutters (5) in accordance with this extent and in addition can be optionally fastened to and radially adjusted on the first partial clamping surface (11a, 26a) or the second partial clamping surface (11b, 26b). The boring head permits the conventional roughing work and is especially stable while being produced at a low cost.Type: GrantFiled: March 15, 2011Date of Patent: June 10, 2014Assignee: Heinz Kaiser AGInventors: Rudolf Stadelmann, Gottlieb Abderhalden, Ralph Stadelmann

Patent number: 7585139Abstract: The boring tool has a tool body (2) on which a tool carrier (10) is mounted in a radially adjustable manner. A setting member (42) serves to set the boring diameter. A drive mechanism converts a rotation of the setting member (42) into a displacement of the tool carrier (10). The drive mechanism has a differential spindle (13) which converts a rotation of a graduated disk (26) into a displacement of the tool carrier (10) for the fine setting of the boring diameter. The differential spindle (13) is mounted in a bore (51) of the tool carrier (10) and extends at right angles to the rotation axis (A).Type: GrantFiled: April 26, 2006Date of Patent: September 8, 2009Assignee: Heinz Kaiser AGInventors: Rudolf Stadelmann, Ralph Stadelmann, Ernst Hänggi

Patent number: 7407349Abstract: The boring tool having a basic body (2) in which a tool bit (27) is arranged which has a cutting edge (29) at a front end (27b). The basic body (2) has an opening (3) in which the tool bit (27) is pivotably mounted. Setting means (7) serve to set the pivoted position of the tool bit (27) relative to the basic body (2). Means (16) serve to fix the tool bit (27) in the set pivoted position. The tool bit (27) is pivotable about a pivot point (P) which is essentially neutral in terms of unbalance. The tool bit (27) is preferably connected at a rear end (27a) to a radially adjustable slide (7). The slide (7) can be finely adjusted radially, for example with a micrometer screw (9).Type: GrantFiled: July 15, 2005Date of Patent: August 5, 2008Assignee: Heinz Kaiser AGInventors: Heinz Kaiser, Ernst Hänggi, Ralph Stadelmann
