An abrasive article includes a carrier element, an abrasive component, and a bonding region between the abrasive component and the carrier element. The abrasive component includes abrasive particles bound in a metal matrix. The abrasive component further includes a network of interconnected pores substantially filled with an infiltrant. The infiltrant has an infiltrant composition containing at least one metal element. The bonding region includes a bonding metal having a bonding metal composition containing at least one metal element. The bonding region is a region distinct from the carrier element and is a separate phase from the carrier element. An 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. The elemental weight percent difference between the bonding metal composition and the infiltrant composition does not exceed 20 weight percent.

Abrasive tools having a continuous metal phase for bonding an abrasive component to a carrier

A device for securing a plurality of abrasive segments to an abrasive tool is provided. The abrasive tool includes a rotatable body with an outer diameter and an inner diameter. The device includes a carrier element that includes a first portion that accommodates the plurality of abrasive segments and a second portion opposite from the first portion that attaches to the rotatable body. The second portion includes a shoulder extending therefrom that facilitates centering with the rotatable body.

Abrasive tip for abrasive tool and method for forming and replacing thereof

An abrasive article including a base having an annular shape defining a central opening; and a mounting assembly coupled to the base, wherein a portion of the mounting assembly is under a compressive force, and a grinding segment coupled to the mounting member.
