Patent number: 7908947Abstract: The invention relates to a device for damping vibrations and/or controlling the flexion of an object in machining, said device comprising at least one force exchange device which could be a force applying device or a damping device. A such force applying device is for applying a force having a force component directed at right angles to the surface of the object and/or for applying a moment to the object. A damping device of this type is for absorbing vibrations from the object and is adapted to absorb a force component directed at right angles to the surface of the object or to absorb a moment from the object.Type: GrantFiled: November 1, 2004Date of Patent: March 22, 2011Assignee: Teeness ASAInventors: Martin Saeterbø, Even Lund

Patent number: 7857554Abstract: The present invention concerns a system for fixing a cutting head to an adapter for a machine tool. The cutting head includes a first linear flange, a second linear flange substantially parallel to the first linear flange and a unit for holding a cutting bit. A holding jaw is provided for being fixed to the adapter and for engagement with at least one of the linear flanges on the cutting head, and a clamping device for clamping the at least one holding jaw between the at least one flange of the cutting head and the adapter. At least one further clamping device is connected to the adapter for engagement with the second or the linear flanges. Furthermore a cutting head and an adapter is defined.Type: GrantFiled: July 15, 2005Date of Patent: December 28, 2010Assignee: Teeness ASAInventors: Martin Sæterbø, Anders Digernes, Per Bjørvik

Publication number: 20100096228Abstract: The present invention concerns a damper for damping vibrations. The damper includes at least one substantially longitudinal damping body (1) with two end surfaces (21, 22) and one substantially longitudinal surface (20) between these. The damping body (1) includes a longitudinal direction (a) and a transversal direction (t) and is places in a substantially longitudinal cavity (15) with a damping fluid, wherein the cavity (15) defines at least one cavity surface (14) and the damping body (1) defines at least one damping surface. The damping fluid includes a proportion of liquid and a proportion of gas and either the cavity surface (14) or the damping body surface or both are broken to promote formation of foam in the damping fluid in operation.Type: ApplicationFiled: September 5, 2007Publication date: April 22, 2010Applicant: TEENESS ASAInventors: Anders Digernes, Arne Martin Nordmark, Roger Olsen

Patent number: 7681869Abstract: The present invention concerns a damping apparatus for the damping of vibrations in tool holders, machine elements and work pieces in machine tools and in other objects that are exposed to unwanted vibrations. The damping apparatus is adapted to be provided in or on the object and includes a substantially cylindrically shaped damping body with a boring going there through and a longitudinal central body that is rigidly connectable to the object that is to be damped. The damping body is connected to the longitudinal central body through elastic elements. The connection is made such that the elastic elements are substantially exposed to shear forces during damping.Type: GrantFiled: April 14, 2003Date of Patent: March 23, 2010Assignee: Teeness ASAInventor: Anders Digernes

Patent number: 7121768Abstract: The invention concerns a cutting head (13) to be secured in an adapter (9) in a machine tool for chip removing machining. The cutting head (13) comprises a flange with a first side creating a coupling surface (4) adapted for being secured to the adapter (9). On the opposite of the flange, it is situated an other side creating at least one surface (1A) with an outwards extending protrusion (8), with securing means adapted for securing a cutting insert (5) with at least one cutting edge. The weight of the cutting head (13) is reduced as compared to the strength of the cutting head (13), and the natural frequency of the cutting head (13) is thereby increased when this is secured to the adapter (9).Type: GrantFiled: January 15, 2002Date of Patent: October 17, 2006Assignee: Teeness ASAInventors: Trude Hole, Per Björvik, Pål Sollie, Knut S.

Patent number: 6082236Abstract: An adaptor is inserted between a cutting tool and a clamping section of a tool machine. The adaptor comprises a tool clamping part holding the tool, and an adaptor clamping part which is held by the machine. Between the two parts there is a bearing which controls the relative movement between the two parts in such a manner that this movements does not influence machined geometry, dimension or surface of the work piece machined by the tool, to any significant degree, and an elastic damping member which ensures that a possible relative movement between two parts is damped down to a desired degree. Possible vibrations in the tool are thereby kept down on a level where they do not contribute to amplify the normal sound pressure from the machining operation, and an efficient noise suppression is achieved.Type: GrantFiled: September 25, 1998Date of Patent: July 4, 2000Assignee: Teeness A/SInventor: Lauritz I. Andreassen

Patent number: 5413318Abstract: A damping device is constituted by a substantially cylindrical damper body (1) with an axial through bore (6), where the bore (6) accomodates a central pipe (3) which e.g. can lead a cooling liquid. The central pipe (3) is connected rigidly to or into the machine element to be damped, preferably in a cylindrical and axial cavity in a boring bar (9). Ring-shaped, elastic spring elements (2) placed in the ends of the damper body (1) and between the central pipe (3) and the damper body (1), as well as damping oil (4) in the clearance between the central pipe (3) and the damper body (1) transform motion energy into heat and provide the damping action. The stiffness of the spring elements (2) can optionally be adjusted.Type: GrantFiled: August 19, 1993Date of Patent: May 9, 1995Assignee: Teeness ASInventor: Lauritz Andreassen
