Patent number: 6942432Abstract: A milling tool includes a milling body and a plurality of insert-carrying cartridges mounted in the milling body. Each cartridge includes front and rear side surfaces which oppose leading and trailing walls of a pocket formed in the milling body. The cartridge also includes inner and outer flank surfaces which interconnect the front and rear side surfaces. The body includes a slot which opens into the front side surface at a location intermediate the ends of the cartridge, to divide the body into a rigid base portion and an expandable portion. The base portion has a seat for a cutting insert. A threaded hole is formed in the slot intermediate the slot ends to receive a threaded wedge screw. Tightening of the screw causes the expandable portion to be expanded into contact with the leading wall of the pocket and thereby push the base portion into tight contact with the trailing wall of the pocket. Accordingly, the cartridge is secured within the pocket by a tight frictional contact which resists chatter.Type: GrantFiled: March 28, 2003Date of Patent: September 13, 2005Assignee: Sandvik Intellectual Property ABInventors: Kenneth G. Noggle, Lee Reiterman

Patent number: 6409435Abstract: An indexable insert is located on a toolholder with reference to bearing surfaces on the insert and the toolholder which are proximate to the active cutting edge. These bearing surfaces are internal to the peripheral (side) flanks of the insert. Location of the insert in the toolholder is substantially independent of the relation between the toolholder pocket sidewalls and the peripheral flanks of the insert, thereby eliminating sources of error from insert manufacture and pocket manufacture. The insert and toolholder have locating units disposed thereon adapted to matingly engage each other when the insert is placed in the toolholder. At least one of the locator elements has a bearing surface or surfaces that extends through 360° and resulting in less movement of the insert during use.Type: GrantFiled: July 3, 2000Date of Patent: June 25, 2002Assignee: Valenite Inc.Inventors: Yevgeny Kocherovsky, Lee Reiterman, Foye Powell, Edward Santimaw

Patent number: 5775855Abstract: An insert for milling applications in which a radial rake face includes a concave conical portion defined to achieve constant positive radial rake throughout the length of a radial cutting edge at the angle of inclination thereof as the insert is intended to be mounted in a cutter body. The insert includes an axial rake face having a sloping portion defined to achieve positive axial rake as the insert is intended to be mounted in a cutter body. The upper surface of the insert includes planar regions and bend surfaces merging smoothly with the radial rake faces and axial rake faces to assist in chip expulsion during cutting.Type: GrantFiled: June 8, 1995Date of Patent: July 7, 1998Assignee: Valenite Inc.Inventors: Lee Reiterman, James D. Lark, II, Lawrence Plutschuck, Paul R. Doxen

Patent number: 5741095Abstract: A ball end mill and an insert for use in the cutting tool. The insert has a constant angle maintained along the entire clearance face.Type: GrantFiled: January 13, 1997Date of Patent: April 21, 1998Assignee: Valenite Inc.Inventors: Mike Charron, Foye Powell, Lee Reiterman

Patent number: 5556239Abstract: An polygonal indexable insert for use in periphery milling cutters. The insert is a positive insert having compound clearance faces comprised of a curve primary clearance surface adjacent the cutting edge and a planar secondary clearance surface adjacent the clearance edge of the insert. The curved primary clearance surface imparts improved strength to the cutting edge of the insert.Type: GrantFiled: October 24, 1995Date of Patent: September 17, 1996Assignee: Valenite Inc.Inventor: Lee Reiterman
-
Patent number: 5513931Abstract: An insert for a peripheral rotary milling cutter having replaceable cutting inserts. Each cutting insert having a cutting rake surface and a relief flank surface and an elliptical cutting edge defined between the cutting rake surface and the relief flank surface.Type: GrantFiled: July 19, 1994Date of Patent: May 7, 1996Assignee: Valenite Inc.Inventors: Lee Reiterman, Paul R. Doxen, James D. Lark, II

Patent number: 5320458Abstract: A cutting tool includes a rotary bar having an arcuate pocket in its side surface, and a segmental carrier arcuately slidable in the pocket to adjust the position of a cutting tip on a cutter blade. The carrier has a second arcuate pocket that slidably receives a segment-shaped shoe, such that the shoe can be arcuately adjusted to control or vary the back taper angle on the blade. The cutting blade is mounted flatwise on one face of the shoe, such that a corner tip on the blade projects beyond the profile of the rotary bar for use in reaming a hole in a workpiece. The adjustment axis of the shoe is coincident with the cutting tip on the reamer blade so that adjusting motions of the shoe do not disturb the position of the cutting tip achieved by arcuate adjustment of the carrier.Type: GrantFiled: May 24, 1993Date of Patent: June 14, 1994Assignee: Valenite Inc.Inventors: Lee Reiterman, Kenneth G. Noggle

Patent number: 5183363Abstract: A non-contact coolant supply apparatus for supplying coolant for cutting a workpiece wherein there is relative cutting motion about an axis of rotation between a cutting member mounted on a tool shank.Type: GrantFiled: July 17, 1992Date of Patent: February 2, 1993Assignee: GTE Valenite CorporationInventors: Lee Reiterman, Dale D. Martin, Joseph Krysik

Patent number: 4964322Abstract: A differential drive for rotation of a central shaft correspoding in contrast to a conventional axially displaced drawbar. The invention employs a harmonic drive gear arrangement having a stationary axle and a servo motor driven rotary axle to produce zero differential out of the radial spline when the servo driven axle is stationary. Servo controllled displacement occurs through rotation of the servo driven axle with a substantial reduction with respect to rotation of the stationary axle, e.g., in the order of 97:1.Type: GrantFiled: September 3, 1987Date of Patent: October 23, 1990Assignee: GTE Valenite CorporationInventor: Lee Reiterman

Patent number: 4948305Abstract: Boring bar having plural circumferentially spaced cutting inserts with incremental radial and axial spacing for innermost radial and foremost axial to outermost radial and rearmost axial in progressive sequence relative to the direction of rotation.Type: GrantFiled: December 23, 1988Date of Patent: August 14, 1990Assignee: GTE Valenite CorporationInventor: Lee Reiterman
-
Patent number: 4927301Abstract: An adjustable cartridge to be mounted in a boring bar, the cartridge including a anvil rotatably affixed to said boring bar, the anvil including a pocket into which a lay-down indexable insert is affixed. The anvil is secured in an axially oriented slot which includes an arcuate seating face. Rotation of the anvil within the slot effects radial adjustment of the insert.Type: GrantFiled: December 27, 1988Date of Patent: May 22, 1990Assignee: GTE Valenite CorporationInventor: Lee Reiterman

Patent number: 4852438Abstract: A rotary tool generating head with radial tool slide feed-out produced by differential rotation of central shaft. A harmonic drive gear having a stationary axle and a servo motor driven rotary axle is used to produce zero feedout of the radial slide when the servo driven axle is stationary. Servo controlled radial tool displacement occurs through rotation of the servo driven axle with a substantial reduction in rotational speed with respect to the stationary axle, e.g., in the order of 97:1.Type: GrantFiled: September 11, 1987Date of Patent: August 1, 1989Assignee: GTE Valenite CorporationInventor: Lee Reiterman

Patent number: 4662254Abstract: Quick change cutting tool block clamp wherein planar mounting faces of adapter base and tool holder faces are located and retained in compressive engagement through linear interengagement of transverse semi-dovetail key surfaces under pressure established by a spaced pivoted clamping dog mechanism spanning the engagement faces. Clamping retention is entirely accomplished by means immediately adjacent the interface of the planar surfaces leaving the outer surfaces of the tool holder open and free of clamp actuating projections.Type: GrantFiled: December 9, 1985Date of Patent: May 5, 1987Assignee: GTE Valeron CorporationInventors: Kenneth G.
