Patent number: 12194545Abstract: A clamping device for releasably holding a tool holder shank includes a housing, a drawbar axially moveable in a bore in the housing between an advanced releasing position and a retracted locking position, engagement members moveable under the effect of the drawbar into locking engagement with the tool holder shank, and a sleeve arranged around a wall of the housing and axially moveable in relation to it. A first wedge is received in a first aperture in the wall and configured to move the drawbar rearwards in the bore when pressed radially inwards in the aperture by movement of the sleeve in a first axial direction. A second wedge is received in a second aperture in the wall and configured to move the drawbar forwards in the bore when pressed radially inwards in the aperture by movement of said sleeve in an opposite axial direction.Type: GrantFiled: December 9, 2020Date of Patent: January 14, 2025Assignee: AB Sandvik CoromantInventor: Gunnar Matlik

Patent number: 11951553Abstract: A cutting head rotatable about a central axis, comprising a tip portion and an intermediate portion. The tip portion has an axially forwardmost tip point contained in the central axis and three axially forward facing front surfaces forming three chisel edges extending axially rearwardly away from the tip point, each front surface having a radially extending cutting edge comprising a secondary cutting-edge portion extending radially outwardly from one of the chisel edges, and a primary cutting-edge portion extending radially outwardly therefrom. Each primary cutting-edge portion is contained in an imaginary annular ring surface having an annular ring width spanning at least radially inner and outer end points thereof. In a front-end view of the cutting head, each primary cutting-edge portion is concave, and radial planes intersect the imaginary annular surface to form imaginary rectilinear lines, each having a length equal to the annular ring width.Type: GrantFiled: March 29, 2021Date of Patent: April 9, 2024Assignee: ISCAR, LTD.Inventors: Shim'on Shitrit, Hytham Kablan

Patent number: 11833592Abstract: An upper drill tool including a central chuck, an upper component, a lower component and a coupling assembly. The central chuck has a chuck base and a chuck structurally configured to retain a drill bit. The upper component is attached to the central chuck and has a lower stop surface. The lower component has a central body and an outer ring that threadedly engages the central body, with the outer ring having an upper stop. The coupling assembly is configured to facilitate the slidable movement of the lower component from a first orientation wherein the upper stop is spaced apart from the lower stop surface and a second orientation wherein the upper stop is in abutting engagement with the lower stop surface, with the first orientation and the second orientation defining a stroke.Type: GrantFiled: February 8, 2021Date of Patent: December 5, 2023Assignee: JR Automation Technologies, LLCInventors: Joseph Robert Russell, Jason R. Turman, Ryan Nathan Anderson, Marcos Merino, Gabriel C. Van't Land

Patent number: 11498134Abstract: The present invention belongs to the technical field of machining of fiber-reinforced composites, and relates to a method for measuring distribution of a thrust force during drilling of a unidirectional composite along with a fiber cutting angle. The method includes: cutting the surface a composite sample piece to form a groove; drilling on an existing experimental platform for measuring a thrust force during drilling, where a through hole obtained through the drilling is required to intersect with the groove; obtaining a curve of the thrust force during drilling, comparing the curve with a conventional curve of the thrust force to find a mutation point, and determining the mutation point, namely a fiber cutting angle at the groove; and calculating fluctuation periods of the thrust force according to machining parameters to reckon the distribution of the thrust force along with the fiber cutting angle in all the periods.Type: GrantFiled: August 11, 2020Date of Patent: November 15, 2022Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Fuji Wang, Jiaxuan Hao, Yu Bai, Wei Liu, Jianwei Ma

Patent number: 11413696Abstract: An indexable cutting tool stably clamps cutting inserts and prevents contact between head parts of fasteners and workpieces. Recesses with a bottom are formed in an upper surface of a cutting insert. Part of an inner wall surface of each recess curves and bulges toward a center axis of the recess. The recess is divided into first to fourth regions by a first imaginary reference plane parallel to a rotation axis of a body, and a second imaginary reference plane perpendicular to the rotation axis. The second region is on a center side and on a proximal side of the body. A tapered surface of a fastener contacts the curved surface within the second region. A center axis of the fastener inclines so a head part opposite a distal end part is closer to the center side and to the proximal side of the body than the distal end part.Type: GrantFiled: January 7, 2020Date of Patent: August 16, 2022Assignee: TUNGALOY CORPORATIONInventor: Hikaru Shiroma

Patent number: 11400523Abstract: A drilling tool, in particular a spiral drill, has a drill longitudinal axis, at least two flutes extending at a twist angle with respect to the drill longitudinal axis, webs formed between the flutes, and lands formed on a lateral surface of the webs. Guide rings are at least partially formed on the lands. The guide rings extend at an angle different from the twist angle to the drill longitudinal axis. At least one guide chamfer is formed on at least one land in addition to the guide rings. The guide chamfer extends parallel to the twist angle and in front of the guide rings with respect to the direction of rotation of the drilling tool.Type: GrantFiled: March 8, 2018Date of Patent: August 2, 2022Assignee: CERATIZIT BALZHEIM GMBH & CO.
