Patent number: 7600543Abstract: A stump grinding disk includes a metallic wheel defining an axis of rotation and including a pair of side surfaces and a circumferential outer edge surface. The outer edge surface includes a plurality of circumferentially spaced recesses. Each recess extends axially completely through the disk. A plurality of side cutting elements are mounted on each side surface. A plurality of outer peripheral cutters are spaced circumferentially apart around the outer edge surface. Wear strips are mounted in respective recesses. Each wear strip includes a metal matrix in which hard particles are disposed. Each wear strip defines a radially inner surface affixed to the wheel, and a radially outer surface arranged substantially flush with adjacent portions of the outer edge surface.Type: GrantFiled: July 13, 2006Date of Patent: October 13, 2009Assignee: Sandvik Intellectual Property ABInventors: Kenneth Monyak, James Paumier

Patent number: 6848485Abstract: A stump grinding mechanism includes a disc having recesses formed in an outer peripheral surface thereof. Peripheral cutting assemblies are mounted in respective recesses. Each cutting assembly includes a holder fixed in the recess, and a cutter tooth mounted in the holder. The cutter tooth includes a shank extending through the holder and secured thereto by a nut. The nut is disposed within a pocket of the holder to be shielded during a cutting operation. The holder includes gauge marks to facilitate a proper angular orienting of the cutting assembly within the recess. Some of the cutter teeth have flat cutter faces optimized for cutting wood fiber, whereas others of the cutter teeth have cutter faces defined by converging surface portions to be optimized for cutting/displacing rocks.Type: GrantFiled: January 21, 2004Date of Patent: February 1, 2005Assignee: Sandvik Mgt LLCInventors: James Paumier, Kenneth Monyak

Patent number: 6546977Abstract: A stump grinding device includes a wheel having an outer peripheral edge in which a plurality of recesses are formed. Disposed in each recess is a plurality of cutting units each including a block affixed to a floor of the recess, and a bit mounted in the block. Each bit includes a hard tip disposed at a front end thereof. The bits of some of the peripheral cutting units are rotatable relative to their respective blocks, with the hard tips thereof being generally pointed. The bits of others of the peripheral cutting units are non-rotatable to their respective blocks, with the hard tips thereof forming elongated cutting edges. The peripheral cutting units are spaced from leading and trailing ends of the respective recesses to provide spaces for the passage of cuttings.Type: GrantFiled: January 29, 2002Date of Patent: April 15, 2003Assignee: Sandvik Rock Tools, Inc.Inventors: Kenneth Monyak, James Paumier

Patent number: 6382277Abstract: A stump grinding tool includes a rotary cutting wheel having a pair of side surfaces and an outer peripheral surface. Cutting assemblies are mounted on the cutting wheel, each cutting assembly including first and second pockets disposed on respective side surfaces of the wheel. Each pocket includes a leading through-hole and a trailing through-hole aligned with respective leading end trailing through-holes of the other pocket for receiving a pair of cutting teeth. Each tooth extends through aligned through-holes of the pocket and cutting wheel in mutually opposite directions, wherein cutting elements of the teeth are disposed adjacent respective ones of the side surfaces. Each tooth is fixed by a nut threaded thereon such that each tooth and associated nut functions to clamp both of the first and second pockets against the respective side-surfaces of the cutting wheel.Type: GrantFiled: April 19, 2001Date of Patent: May 7, 2002Assignee: Sandvik Rock Tools, Inc.Inventors: James Paumier, Kenneth Monyak
