Patent number: 9815131Abstract: A reamer or similar tool comprising a cutting device having a cutting edge, a clamping device, whereby the cutting device can be clamped to the main body of the tool, an adjusting device that interacts with the cutting device, for adjusting the machining diameter of the tool, and a guiding device comprising an elongated guiding element, which interacts with an elongated guiding receptacle such that the cutting device can be guided in a sliding manner perpendicularly to the center axis during a displacement when the adjusting device is activated. The guiding element and the guiding receptacle extend perpendicularly to the center axis of the main body of the tool. The guiding device of the tool has a single guiding element and/or a single guiding receptacle, and the guiding element has an elongated elevation and the guiding receptacle has an elongated recess.Type: GrantFiled: September 13, 2013Date of Patent: November 14, 2017Assignee: MAPAL FABRIK FUR PRAZISIONWERKZEUGE DR.

Publication number: 20100196110Abstract: A reamer is proposed, having a basic body (3), at least one cutting tip (13) disposed essentially parallel to a face (11) of the reamer (1), which has a geometrically defined major cutting edge and a geometrically defined minor cutting edge (29, 27), and is held on a support surface (19) of the base body (3) by a tightening screw (39) that penetrates the cutting tip (13), where a back (17) of the cutting tip (13), which is polygonal in a bottom view, lies against the support surface (19), and having an adjustment device having an adjustment screw that acts on the cutting tip (13), which screw introduces adjustment forces into a side surface of the cutting tip (13). The reamer is characterized in that the ratio of the diameter (55) of an imaginary in-circle (53) that is tangential to the side edges (41, 41?, 45, 45?) of the back (17) of the cutting tip (13), relative to the thickness (d) of the cutting tip (13), lies in a range of 1.0 to 1.5, preferably in a range of 1.2 to 1.5.Type: ApplicationFiled: September 2, 2008Publication date: August 5, 2010Applicant: MAPAL FABRIK FUR PRAZISIONWERKZEUGE DR.

Publication number: 20060140736Abstract: An interface between two parts of a tool system is proposed, in particular of a metalworking tool (1), having a holder (3) with a recess (31) and a replaceable head (5) disposed in axial continuation to the holder (3) including an extension (33) which can be inserted into the recess (31), and having a clamping device (19) to attach the replaceable head (5) to the holder (3). The clamping device is characterized by the clamping device (19) having a pull stud (41) and an eccentric cam (21) which displaces same in the axial direction, where the eccentric cam (21) can be actuated by way of a peripheral surface (17) of the metalworking tool (1).Type: ApplicationFiled: May 29, 2004Publication date: June 29, 2006Applicant: Mapal Fabrik fur Prazisionwerkzeuge Dr. Kress KGInventors: Dieter Kress, Friedrich Haberle

Patent number: 6776553Abstract: Proposed is a connecting point between two tool parts with a device, comprising an elastic element, for effecting a defined angular position of rotation between the tool parts. Said connecting point is characterized in that the elastic element (23) in a first area (43) is clamped to the first tool part (3) in such a manner that in connecting the tool parts (3, 7) a second area (25) projects into the path of motion of the second tool part (7) so that it is deflected by said tool part and is deformed reversibly.Type: GrantFiled: March 18, 2002Date of Patent: August 17, 2004Assignee: MaPal Fabrik für Präzisionwerkzeuge Dr. Kress KGInventor: Dieter Kress

Patent number: 6050159Abstract: A facing head includes a housing with a center axis and a rotary slide with a rotation axis offset from the housing center axis. At least one cutter plate is provided on the rotary slide and rotatable therewith. A centrifugal drive is located in the housing which rotates the rotary slide about its axis of rotation. The centrifugal drive includes at least two driving bodies which are mounted within the base body of the facing head and which are displaceable essentially perpendicular to the center axis under the influence of centrifugal force. The rotary slide rotates under the influence of a spring return device when centrifugal force does not move the driving bodies outward. A coupling device in the form of a gear wheel on the rotary slide co-operates with racks on the driving bodies so that the driving bodies move together but in opposition.Type: GrantFiled: February 1, 1999Date of Patent: April 18, 2000Assignee: Mapal Fabrik fur PrazisionwerkzeugeInventors: Dieter Kress, Hans W. Beck, Herbert Jager
