Patent number: 9004823Abstract: A family of rotating cutting tools includes at least two toolholders having different diameters, each toolholder including a first side and a second side, the first side and the second side being substantially perpendicular to an axis of rotation of the toolholder, and at least one insert abutment surface on each of the first side and the second side. For each toolholder, the insert abutment surfaces on the first and second sides define an angle with a plane perpendicular to the axis of rotation of the toolholder, and the angle defined by the insert abutment surfaces and the plane perpendicular to the axis of rotation of the toolholder is different for the at least two toolholders having different diameters.Type: GrantFiled: March 1, 2010Date of Patent: April 14, 2015Assignee: Seco Tools ABInventor: Christer Ejderklint

Patent number: 8465233Abstract: A slot-milling tool includes a slot-milling insert to be on-edge mounted to a toolholder of the slot-milling tool. The insert includes a first side surface, a second side surface, and a plurality of edge surfaces between the first and second side surfaces, each edge surface intersecting with another edge surface at a corner and forming a cutting edge. The first and second side surfaces each have a side insert supporting surface for abutting against an abutment surface in a toolholder, and the insert has reflective symmetry about a central plane extending through the edge surfaces midway between the first and second side surfaces. A chipbreaker is provided on each edge surface and corresponds to each cutting edge, and each chipbreaker includes a recess beneath the cutting edge and a portion projecting toward the cutting edge, the projecting portion defining first and second chip deflecting recesses between the projecting portion and the first and second side surfaces, respectively.Type: GrantFiled: March 1, 2010Date of Patent: June 18, 2013Assignee: Seco Tools ABInventor: Christer Ejderklint

Patent number: 7478978Abstract: The present invention relates to a tool head preferably for milling. The tool head is connectable to a toolholder. The tool head includes a cutting portion and a mounting portion. The mounting portion includes an axial stop surface and a radial stop surface. Dimensions and tolerances of the axial stop surface and the radial stop surface are selected such that the axial stop surface will abut an axial stop on the toolholder to prevent axial movement of the toolholder relative to the tool head beyond the axial stop surface and the radial stop surface will be disposed proximate a radial stop of the toolholder to limit radial movement of the tool head relative to the toolholder when an integral fastening portion of the tool head and an integral fastening portion of the toolholder are fastened directly to one another and the axial stop surface and the axial stop abut.Type: GrantFiled: November 30, 2007Date of Patent: January 20, 2009Assignee: Seco Tools ABInventors: Christer Jonsson, Bengt Högrelius, Jan Eriksson, Christer Ejderklint, Carl-Erik Berglöw, Jorma Koskinen, Jonas Boman

Patent number: 7410331Abstract: In a cutting insert and a milling tool, where the cutting insert is to be on-edge mounted to the tool, the cutting insert includes a polygonal body of wear resistant material. The body includes a first side surface and a second side surface opposing one another and therebetween a number of end surfaces. The intersection of two end surfaces form a cutting edge at a corner portion. The first side surface is substantially planar and the second side surface connects to raised portions at corner portions. The first side surface is greater than the second side surface.Type: GrantFiled: June 29, 2006Date of Patent: August 12, 2008Assignee: Seco Tools ABInventors: Christer Ejderklint, Bertrand Riviere, Dominique Meyer
