The disclosed technology includes a cutting tool comprising segments arranged around a periphery of a cutting tool. Each segment, of the plurality of segments comprising a first portion comprising a first material having a first hardness, a second portion comprising a second material having a second hardness, the second hardness being less than the first hardness, and a transition region. The transition region can include at least part of the first material and at least part of the second material. The transition region can have an overall third hardness that is less than the first hardness and greater than the second hardness. A first segment and a second segment of the plurality of segments can be attached to the periphery of the cutting tool such that at least the first portion of the first segment is aligned in a cutting direction with the second portion of the second segment.

The disclosed technology includes an abrasive cutting tool having a plurality of segments arranged around a periphery of the cutting tool. The plurality of segments can include a first segment having a first portion having a first concentration of abrasive material, and a second portion having a second concentration of abrasive material. The second concentration can be less than the first concentration. The cutting tool can have a second segment having a third portion having a concentration of abrasive material that can be similar to the concentration of the first portion, and a fourth portion having a concentration of abrasive material that can be similar to the concentration of the second portion. The first portion and the second portion can be reciprocally arranged in relation to the third portion and the fourth portion around the periphery of the cutting tool.

A tool for generating tooth systems by grinding when the maximum tool diameter is limited by collision contours on the workpiece has a dressable grinding tool that is tightly connected to the tool holder. In one preferred arrangement, the dressable grinding tool is glued on the tool holder.

An abrasive article comprises an abrasive portion having an annular shape defined by an inner annular surface, the abrasive portion including abrasive particles contained in a bond material, and wherein the abrasive portion comprises at least one circumferential groove in an outer annular surface; and a backing coupled to the inner annular surface of the abrasive portion.

A double-sided flap disc for use on a mounted grinder. A carrier plate has abrasive flaps attached around its outer perimeter on both sides. The flaps are arranged so that each side mirrors the other, that is, the flaps attached to one side face clockwise and the flaps attached to the other side face counterclockwise. This allows a U-shaped workpiece, such as a horseshoe, to be moved side to side against both sides of the disc, to provide symmetrical grinding.

A method of processing a ferrule end face using at least one grinding wheel rotatable about a central axis and having a working surface with an abrasive element is provided. The method includes holding the ferrule stationary, engaging the end face of the ferrule and the working surface of the at least one grinding wheel, rotating the at least one grinding wheel about the central axis, and moving the at least one grinding wheel relative to the ferrule along a curve perpendicular to the central axis. Processing the ferrule in this manner imparts a convex shape of the end face of the ferrule. An apparatus for carrying out the method is also disclosed.

A grinding wheel assembly is disclosed and includes an arbor in which a pull stud may be installed. Further, the arbor can include a head assembly that includes a mounting plate, a cover plate, and an abrasive body disposed there between. The abrasive is removably engaged with the mounting plate and the cover plate.

A rotary abrasive machining tool (101) is shown. The tool comprises a hub (103) having plurality of axially-oriented radial slots in the outer circumference thereof, and plurality of abrasive segments each of which is located in a respective slot in the hub and which form an abrading surface (102). The abrasive segments comprise a tab for location in a slot in the hub, and an abrading edge defining a plurality of abrasive elements.

A grinding wheel assembly is disclosed and includes an arbor in which a pull stud may be installed. Further, the arbor can include a head assembly that includes a mounting plate, a cover plate, and an abrasive body disposed there between. The abrasive is removably engaged with the mounting plate and the cover plate.

A method of manufacturing a rotary abrasive machining tool, the rotary abrasive machining tool including a hub and a plurality of abrasive segments mounted to the hub, the method including the steps of: mounting each abrasive segment on the hub; machining an abrading edge on each abrasive segment while the abrasive segment is mounted on the hub.
