Patent number: 7637701Abstract: A tool and a cutting insert for chip removing machining, such as milling, turning or the like. The cutting insert includes a chip-removing main edge, which is separated from a center of the cutting insert and from which a clearance surface extends toward a transition to an underside in the form of a connecting surface, in which an elongate engagement means, e.g., a ridge, is included, which is situated nearer the transition than the center of the cutting insert, and includes a flank having the purpose of transferring cutting forces in the direction transverse to the length extension of the ridge. The ridge is the only active engagement means of an imaginary triangle between the center of the cutting insert and opposite ends of the transition, besides which the flank has a cross section-wise convex shape. In such a way, the active edge of the cutting insert is located in a desired exact position in relation to the tool, even if the cutting insert is impaired by minor form defects.Type: GrantFiled: December 4, 2006Date of Patent: December 29, 2009Assignee: Sandvik Intellectual Property ABInventor: Göran Pantzar

Patent number: 6942431Abstract: A rotatable cutting tool, e.g., a milling cutter, includes a rotatable base body and a cutting insert, which in addition to two opposite side surfaces has front and rear end surfaces. For axial fine-adjustment of the cutting insert, a set screw is arranged that is located in an area behind the cutting insert and inclined at an obtuse angle to a side surface of the cutting insert. During an unscrewing of the set screw, it presses against the rear end surface of the cutting insert with the purpose of moving the cutting insert in the direction axially forwards, whereby the screw, due to the obtuse angle, is centrifugally secured by means of the actual cutting insert.Type: GrantFiled: November 20, 2002Date of Patent: September 13, 2005Assignee: Sandvik AntiebolagInventors: Göran Pantzar, Lars Hellström

Patent number: 6709204Abstract: A rotatable tool includes a rotatable body defining an axis of rotation. The body forms a seat configured to receive a cutting insert. The seat includes a bottom surface and a radial support upstanding therefrom. The bottom surface includes a screw-receiving hole which intersects the bottom surface to form a port therein. The screw-receiving hole includes a female screw-threaded portion spaced from the port by a non-threaded portion. A fastening screw secures the cutting insert to the body. The screw includes a shaft having at one end thereof a male screw thread connectable to the female screw threaded portion, and at an opposite end thereof a head. The shaft also includes a non-threaded portion disposed between the male screw thread and the head and sized to be received in the non-threaded portion of the screw-receiving hole.Type: GrantFiled: August 9, 2002Date of Patent: March 23, 2004Assignee: Sandvik AktiebolagInventors: Lars Hellström, Göran Pantzar

Patent number: 6619891Abstract: A rotatable milling tool includes a body, and at least one set of circumferentially spaced cutting members that are intersected by a common plane oriented perpendicularly to a longitudinal center axis of the body. The set of cutting members includes at least three cutting members mounted in an envelope surface of the body. Each cutting member includes a flank surface and a cutting edge disposed adjacent to the flank surface. Each cutting edge has axially spaced apart ends. The flanked surface of each cutting member forms a clearance angle with a tangent extending through the respective cutting edge. The flank surface of the insert has a larger clearance angle than the flank surfaces of at least two other inserts in the same set. During a milling operation, the cutting members with smaller clearance angles tend to produce stability and vibration-free rotation, while the cutting member having the larger clearance angle ensures a high precision (smooth) machining.Type: GrantFiled: April 30, 2001Date of Patent: September 16, 2003Assignee: Sandvik AktiebolagInventors: Lars-Ola Hansson, Göran Pantzar, Inge Svenningsson
