Abstract:
1. A device for securing a plurality of abrasive segments to an abrasive tool having a rotatable body with an outer diameter and an inner diameter, the device comprising: a carrier element having a first portion on which each of the abrasive segments of the plurality of abrasive segments is affixed and a second portion opposite from the first portion that attaches to the rotatable body, the second portion comprising a shoulder extending therefrom that facilitates centering with the rotatable body, and a bonding region between each abrasive segment of the plurality of abrasive segments and the first portion of the carrier element, the bonding region comprising a bonding metal continuous with an infiltrant filling a network of interconnected pores within each abrasive segment of the plurality of abrasive segments; wherein the carrier element defines a split ring having a uniform cross-sectional dimension extending throughout an entire circumference of the split ring and a single slot extending completely through the first portion of the carrier element and the second portion of the carrier element between adjacent abrasive segments; wherein the first portion comprises a groove configured to accommodate an abrasive segment of the plurality of abrasive segments; wherein the bonding metal includes a bonding metal composition containing at least one metal element, and the infiltrant includes an infiltrant composition containing at least one metal element; wherein the bonding metal composition and the infiltrant composition are compositionally similar to each other; and wherein an elemental weight percent difference between the bonding metal composition and the infiltrant composition does not exceed 20 weight percent, wherein the elemental weight percent difference is the absolute value of the difference in weight content of each element contained in the bonding metal composition relative to the infiltrant composition.
