Abstract: A honing tool for honing holes in workpieces, having an abrasive portion including a first abrasive layer therearound of abrasive particles of a first size, including a region having a second abrasive layer of abrasive layers of a second size sufficiently smaller than the first size, so as to be disposed in interstices between abrasive particles of the first abrasive layer without altering the diametrical size of the first layer, and so as to provide enhanced wear resistance.

Abstract: A device for honing blind bores in parts, a blind bore including a cylindrical bore open at one end and closed adjacent to the opposite end including a honing mandrel for mounting on a honing machine that produces rotation thereof, the mandrel having a cylindrical honing portion adjacent one end which portion and the adjacent portion of the mandrel have spaced axially extending slot therethrough to enable the honing portion of the mandrel to expand and contract in size, the honing portion having a portion adjacent to the end thereof which is somewhat larger than the rest of the honing portion when the honing portion is expanded for honing in the blind hole, the end portions of the mandrel between the spaced slots being elastically expandable from a retracted position which is less than the diameter of the surface to be honed to enable insertion therein to a more expanded condition wherein the diameter of the honing portion at the largest point is the diameter at which the mandrel will hone the blind hole.

Abstract: A honing member for use in honing the external cylindrical surface of a workpiece comprising an elongated annular member having a passageway extending the entire length therethrough, the inner annular surface of such passageway having abrasive particles attached directly thereto or formed integrally therewith, the inner annular surface being substantially cylindrical in shape and having at least one tapered portion adjacent one end portion of the honing member, and a slot formed through one side portion of the annular member extending the full length thereof to facilitate expansion and contraction thereof to radially adjust the diameter of the inner surface of the annular member.

Abstract: A honing device for mounting on a honing tool for rotation therewith including a backing material having opposite end surfaces, opposite side surfaces, and an edge surface extending between the opposed end and side surfaces, and a layer of an abrasive such as a superabrasive material and a binder attached onto one of the side faces and extending therealong to the edge surface whereby an edge of the abrasive layer and the adjacent edge surface engage the workpiece surface to be honed.

Abstract: A honing tool or mandrel mountable for rotation on a honing machine comprising a tubular abrasive sleeve member retained coaxially within a modular tubular honing assembly having an opening or passageway extending the entire length therethrough adaptable for insertably receiving an elongated expander member positioned for axial movement therewithin. The modular tubular honing assembly includes a drive member for attaching to a typical honing machine, a cage member adaptable for slidably receiving the abrasive sleeve member, and a retainer member for holding the abrasive sleeve member in operative position within the cage member. The abrasive sleeve member has inner and outer surfaces, the inner surface being conically tapered over its entire length while its outer surface includes a plurality of circumferentially spaced longitudinal projections positioned adjacent longitudinal channels, each projection including a honing surface having abrasive particles located thereon.

Abstract: An improved method for plating super abrasive materials onto the working portion of a honing tool, which method includes plating or otherwise coating a relatively thin layer of a composite material comprising a metal or metal alloy material having a friction reducing or lubricating type material occluded or otherwise associated therewith over the top of the bond already established between the abrasive particles and the working portion of the honing tool so as to substantially reduce and minimize the occurrence of having stock material build-up and collect between the abrasive particles, which stock build-up causes galling or scoring of the honed work surface during a honing operation. In the preferred embodiment, the composite material comprising the anti-galling coating surface is a nickel/phosphorous alloy material having micron-sized Teflon particles occluded therein.

Abstract: A honing tool or mandrel mountable for rotation on a honing machine comprising an elongated substantially tubular member having inner and outer surfaces, the inner surface being conically tapered over substantially the length thereof, the outer surface including a portion having abrasive particles thereon, an elongated expander member positioned extending through the tubular member and having an outer surface tapered for making surface-to-surface contact with the tapered inner surface of the tubular member, the expander member being axially movable within the tubular member to change the diameter thereof uniformly along its length, the tubular member being attachable to a honing machine for rotation therewith adjacent one end portion thereof by a mounting structure which enables the tubular member to expand and contract thereat to increase or decrease the diameter thereof.

Abstract: A tool and a grinding member for installing thereon comprising a support structure having inner and outer portions journaled for relative rotational movement, a guide member for mounting on an object having a surface to be ground, the guide member having a cylindrical portion that extends from the object in a position centered on the axis of the surface to be ground, the inner portion of the support structure having a surface for making sliding engagement with the cylindrical guide portion, a work engaging member for mounting on the outer portion of the support structure in position to engage the surface to be ground when the tool is moved axially along the cylindrical portion of the guide member, the work engaging member having a surface portion contoured to the desired shape of the surface to be ground and having surface grooves formed therein at spaced locations extending thereacross, and a layer of relatively hard, wear resistant materials and a binder formed on the contoured surface of the work engaging
