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: 7281888Abstract: The tool exhibits a first tool part (2) and a second tool part (3), which possess a common axis of rotation (A). The first tool part (2) is provided with an alignment pin (4) and exhibits at its root an annular surface (5). The second tool part (3) possesses an axial bore (7) to receive the alignment pin (4) and an annular surface (6), which is capable of being tensioned against the annular surface (5) of the first tool part (2). Tensioning structures (8, 9, 10) serve for the axial tensioning of the two tool parts (2, 3) to one another. The tensioning structures (8, 9, 10) exhibit three retaining screws (8, 9, 10) arranged distributed around the periphery of the second tool part (3), which retaining screws are each screwed radially into a threaded bore (12, 13, 14) of the second tool part (3) and each engage in a radial bore (21, 22, 23) of the alignment pin (4).Type: GrantFiled: February 9, 2007Date of Patent: October 16, 2007Assignee: Heinz Kaiser AGInventors: Heinz Kaiser, Ernst Hänggi, Rudolf Stadelmann

Patent number: 4955767Abstract: A boring attachment has a boring head with a transversely adjustable slide for setting the boring cutter. The slide has a bore for receiving (clamping) a holding device, at a length which is adjustable in the axial direction, so that the holding device is longitudinally displaceable by an amount equaling at least twice the diameter of the recess. Loading at the cutter holder is essentially completely eliminated when the holding device is located in a transversely displaced position which is within the principle operating range of the boring head by providing appropriate bores in the body of the boring head. A relatively small overall height for the boring head contributes to optimal stability of the boring attachment.Type: GrantFiled: July 7, 1988Date of Patent: September 11, 1990Assignee: Heinz Kaiser AGInventors: Heinz Kaiser, Rudolf Stadelmann
