Patent number: 8931983Abstract: A milling tool assembly has a replaceable cutter and a reusable shank connected to the cutter with a detachable joint. The joint may be, for example, a threaded connection. An intermediate alignment sleeve made of an elastic or semi-elastic material, is positioned between the cutter and the shank about the axis of rotation of the shank.Type: GrantFiled: May 6, 2009Date of Patent: January 13, 2015Assignee: Kennametal Inc.Inventors: Leonid B. Sharivker, Sergei V. Boulakhov, Vladimir Galipko, Vladimir D. Volokh, Shay Zeidner

Patent number: 8807882Abstract: A face milling cutter has a shank portion adjoining a cutting portion. The cutting portion terminates in a plurality of cutting edges extending in a radial direction from a central axis of the face milling cutter. The cutting edges are convexly curved at least along a part of their length. A portion of the cutting edges proximate the central axis is nearer in an axial direction to the shank portion than a point, X, on the cutting edges that is farthest away from the shank portion. A distance Y, between the point, X, and the central axis is between 20% and 40% of a diameter, D, of the face milling cutter, and a central portion extends the distance, Y, and has a radius of curvature of about 110% of the diameter, D.Type: GrantFiled: October 3, 2008Date of Patent: August 19, 2014Assignee: Hanita Metal Works, Ltd.Inventors: Vladimir Volokh, Sergei Boulakhov, Shay Zeidner, Leonid Sharivker

Publication number: 20130008004Abstract: A method of making chatter-resistant end mills includes: (a) forming an end mill having unequal angular spacing between adjacent teeth, (b) cutting a test work piece with the end mill and measuring vibrations and resonance; (c) upon detecting undesired levels of vibration and resonance, adjusting the angular spacing between adjacent teeth to reduce vibration and resonance and forming another end mill having the adjusted angular spacing; (d) cutting a test work piece with the adjusted end mill and measuring vibrations and resonance; (e) repeating steps (c) and (d) until an end mill is formed in which vibration produced by the angular spacing between at least one pair of adjacent teeth cancels out at least a portion of the vibration produced by the angular spacing between at least one other pair of adjacent teeth; and (f) making at least one production end mill conforming to step (e).Type: ApplicationFiled: July 16, 2012Publication date: January 10, 2013Inventors: VLADIMIR VOLOKH, SERGEI BOULAKHOV, LEONID SHARIVKER, SHAY ZEIDNER, VLADIMIR GALIPKO

Patent number: 7959382Abstract: A center or non-center cutting end mill for orbital drilling includes a shank having a shank diameter; a neck having a neck diameter; a cutting head having a cutting diameter; a corner radius; a dish angle; and a longitudinal axis, the cutting head including a forward cutting end having a convexly curved section located between the longitudinal axis and the corner radius, wherein the convexly curved section causes material removed from a workpiece to flow radially outward from an initial contact area toward the corner radius, thereby minimizing the accumulation of material in a central portion of the forward cutting end.Type: GrantFiled: January 21, 2009Date of Patent: June 14, 2011Assignee: Kennametal Inc.Inventors: Vladimir David Volokh, Sergei Vladimir Boulakhov, Leonid Boris Sharivker, Shay Zeidner, Wangyang Ni, Vladimir Galipko
