Patent number: 6109838Abstract: A face milling cutter comprises a holder adapted to be rotatable about an axis. A plurality of first cutting inserts, and a plurality of second cutting inserts are mounted in respective pockets of the holder. The first and second inserts alternate circumferentially with one another. The first and second inserts are identical and include a center hole for receiving a fastener screw. The central hole of the first inserts are oriented orthogonally relative to the center hole of the second inserts, whereby the first inserts are turned by about 90 degrees relative to the second inserts. The axial relationship of the second inserts relative to the first inserts is determined by shims disposed between the holder and respective ones of the second inserts.Type: GrantFiled: June 10, 1998Date of Patent: August 29, 2000Assignee: Seco Tools ABInventor: Bertrand Riviere

Patent number: 6056484Abstract: Both a device and method for adjusting the position of a cutting insert relative to the body of a cutting tool such as a milling cutter are provided. The device includes a cantilevered wall integrally connected to the tool body, that forms a portion of the pocket in the tool body that supports a side of the insert, and a wedge mechanism for elastically flexing the cantilevered wall to adjust the position of a cutting edge of the insert relative to the tool body. The wedge mechanism may take the form of a screw threadedly engaged to the tool body that has a conical head engaged against the cantilevered wall such that when the screw is turned, the conical wedge formed by the screw head flexes the cantilevered wall a small distance. The device advantageously allows fine adjustments to be made in the position of the cutting edge of an insert by the simple turning of a single screw.Type: GrantFiled: August 7, 1998Date of Patent: May 2, 2000Assignee: Kennametal Inc.Inventors: Robert N. Mitchell, Glenn W. Sheffler, Ronald L. Dudzinsky

Patent number: 6033157Abstract: An adjustment mechanism for adjusting an insert pocket wall's abutment surface in order to alter the location of an insert mounted in the pocket. The adjustment mechanism includes an adjustment screw and adjustment ball located in an adjustment bore. The adjustment ball is located in the vicinity of the pocket wall and on tightening the adjustment screw the adjustment ball is forced against the pocket wall. The force applied by the adjustment ball deforms the pocket wall in the region of contact between the adjustment ball and the pocket wall resulting in the required adjustment of the abutment surface.Type: GrantFiled: May 17, 1999Date of Patent: March 7, 2000Assignee: Iscar Ltd.Inventors: Amir Satran, Yaron Eisen

Patent number: 6024143Abstract: A cutter tooth assembly for impingement of a material (e.g., a stump, wood, brush or earth strata). The assembly attaches to a driven member (e.g., a rotatable wheel). The assembly includes a cutter tooth which has an elongate body with a leading end and a trailing end, as well as a hard insert at the leading end of the tooth. The assembly also includes a pocket which has a base portion and a holder portion. The pocket attaches to the wheel at the base portion thereof. The cutter tooth is retained to the pocket at the holder portion thereof. The base portion of the pocket has a leading surface and a trailing surface. The cutter tooth is retained by the holder portion of the pocket so that the hard insert extends circumferentially past the leading surface of the base portion of the pocket.Type: GrantFiled: March 22, 1999Date of Patent: February 15, 2000Assignee: Kennametal Inc.Inventor: Cary D. Ritchey

Patent number: 6004080Abstract: A milling tool includes a supporting body that is rotatable around a central axis, and is being equipped with detachable cutting inserts. Each insert has two cutting edges extending at a given setting angle relative to each other. One of the cutting edges is located in a reference plane oriented perpendicular to the axis of rotation. In order to directly or indirectly connect each cutting insert with the supporting body a pair of serrated surfaces are provided, each of the serrated surfaces consisting of oblong, parallel ridges that are separated by grooves. A first one of the serrated surfaces is located at an inner side of the cutting insert, and the other one being directly or indirectly associated with the supporting body. The ridges and the grooves of the serrated surfaces are relative to the reference plane by an angle that constitutes one-half of the setting angle.Type: GrantFiled: October 14, 1998Date of Patent: December 21, 1999Assignee: Sandvik ABInventors: Ingemar Qvarth, Lars-Erik Enquist

Patent number: 5863156Abstract: A cutting tool assembly including a cutter body having a cutting unit receiving pocket for releasably receiving a cutting unit with an operative cutting edge and an abutment surface remote therefrom. An elongated bore adapted for receiving an adjustment device is formed in the cutter body, the bore opening into the receiving pocket adjacent the abutment surface. The adjustment device includes an elongated tubular adjustment member having a longitudinally directed adjustment surface inclined with respect to its longitudinal axis, and an elongated adjustment screw initially slidingly extending through the adjustment member. The adjustment member is secured on the adjustment screw such that upon screwing the adjustment screw in a given direction, the adjustment member pushes the cutting unit outward.Type: GrantFiled: March 19, 1997Date of Patent: January 26, 1999Assignee: Iscar Ltd.Inventors: Amir Satran, Dina Agranovsky

Patent number: 5716167Abstract: A cartridge-type milling cutter is provided having a cartridge mounting mechanism that resists the centrifugal load applied to the cartridges at high rotational speeds. The milling cutter includes a generally cylindrical cutter body, at least one replaceable tool cartridge having a trailing face, and a leading face having a cutting insert for cutting a workpiece, and a mounting mechanism for detachably securing the tool cartridge onto the cutter body. The mounting mechanism includes a recess in the cutter body for receiving the cartridge that includes a radially canted wall for providing dovetail-type resistance to radial movement of the cartridge, and at least one compressively loaded set screw in the cutter body for compressively engaging the leading face of the cartridge in order to seat and retain it within the recess. During the operation of the cutter, the centrifugal load is substantially borne by the combination of the radially canted wall and the set screw.Type: GrantFiled: January 16, 1997Date of Patent: February 10, 1998Assignee: Kennametal Inc.Inventors: David R. Siddle, Ted R. Massa, John S. VanKirk, Kenneth M. Malott
