Abstract
Official abstract text for this publication.
An abrasive assembly including a back-up pad having a central axis, an engagement component, and an alignment element; and an abrasive disc having a central axis, the abrasive disc engaged with the back-up pad, the abrasive disc including an alignment element; wherein the alignment element of the back-up pad aligns with the alignment element of the abrasive disc, wherein the engagement component of the back-up pad engages with the abrasive disc, and wherein the back-up pad and the abrasive disc have a concentricity tolerance, C, as measured between the central axis of the back-up pad and the central axis of the abrasive disc, of no greater than about 0.1.
First claim
Opening claim text (preview).
What is claimed is: 1. An abrasive assembly comprising: a back-up pad having a central axis, an engagement component, and an alignment element; and an abrasive disc having a central axis, the abrasive disc engaged with the back-up pad, the abrasive disc including an alignment element; wherein the alignment element of the back-up pad aligns with the alignment element of the abrasive disc, wherein the engagement component of the back-up pad engages with the abrasive disc, and wherein the back-up pad and the abrasive disc have a concentricity tolerance, C, as measured between the central axis of the back-up pad and the central axis of the abrasive disc, of no greater than about 0.1. 2. The abrasive assembly according to claim 1 , wherein the abrasive disc further comprises an engagement component, the engagement component of the abrasive disc engageable with the engagement component of the back-up pad. 3. The abrasive assembly according to claim 2 , wherein the engagement component of the back-up pad and the engagement component of the abrasive disc are disposed along an entire first surface of the back-up pad and an entire first surface of the abrasive disc. 4. The abrasive assembly according to claim 1 , wherein the engagement component comprises a hook-and-loop engagement system. 5. The abrasive assembly according to claim 1 , wherein C is measured after the back-up pad is engaged with the abrasive disc. 6. The abrasive assembly according to claim 1 , wherein the abrasive disc comprises a non-woven abrasive. 7. The abrasive assembly according to claim 1 , wherein the abrasive disc comprises a bonded abrasive.
