Abstract

An abrasive tool comprises an arbor having a body formed with an internal bore, a mounting plate disposed on the arbor, a cover plate, an abrasive article disposed between the mounting plate and the cover plate, and at least one internal resilient member disposed within the internal bore of the arbor.

First claim

What is claimed is:

1 . An abrasive tool comprising:
an arbor having a body formed with an internal bore; a mounting plate on the arbor; a cover plate; an abrasive article disposed between the mounting plate and the cover plate; and at least one internal resilient member disposed within the internal bore of the arbor.

2 . The abrasive tool of claim 1 , further comprising:
a single fastener extending through the cover plate and into the arbor.

3 . The abrasive tool of claim 2 , wherein the single fastener extends through the cover plate, the abrasive article and the mounting plate.

4 . The abrasive tool of claim 3 , wherein the single fastener is configured to be threadably engaged with the arbor.

5 . The abrasive tool of claim 1 , wherein the cover plate is configured to compress the at least one internal resilient member.

6 . An abrasive tool comprising:
an arbor having a body formed with an internal bore; a mounting plate on the arbor; a cover plate having a hub extending therefrom, wherein the hub extends at least partially into the internal bore of the arbor; an abrasive article disposed between the mounting plate and the cover plate; and at least one internal resilient member disposed within the internal bore of the arbor.

7 . The abrasive tool of claim 6 , wherein the at least one resilient member has a length, L RMU , and the internal bore of the arbor has a length, L DCB , and L RMU is less than L DCB .

8 . The abrasive tool of claim 7 , wherein L RMU is less than or equal to 90% L DCB .

9 . The abrasive tool of claim 6 , wherein the internal resilient member comprises a body having an outer surface and a plurality of grooves are formed in the outer surface of the body.

10 . The abrasive tool of claim 9 , wherein the plurality of grooves form a castellated pattern in the outer surface of the internal resilient member.

11 . The abrasive tool of claim 6 , wherein the internal resilient member comprises a polymer.

12 . The abrasive tool of claim 11 , wherein the internal resilient member comprises an elastomer.

13 . The abrasive tool of claim 12 , wherein the internal resilient member comprises polychloroprene.

14 . The abrasive tool of claim 13 , wherein the internal resilient member comprises a neoprene spring rubber.

15 . The abrasive tool of claim 14 , wherein the internal resilient member has a hardness of at least 50 as measured according to Shore A durometer.

16 . An abrasive tool comprising:
an arbor having a body formed with an internal bore; a mounting plate on the arbor; a cover plate disposed on the arbor; an abrasive article disposed on the arbor between the mounting plate and a cover plate; and an internal resilient member disposed within the arbor and spaced a distance from the abrasive article, wherein the internal resilient member is configured to be compressed within the arbor by a fastener that is threadably engaged with the arbor.

17 . The abrasive tool of claim 16 , wherein the mounting plate is integrally formed with the arbor.

18 . The abrasive tool of claim 16 , wherein the mounting plate and the arbor are a single, continuous piece.

19 . The abrasive tool of claim 16 , wherein the at least one resilient member has a length, L RMU , and the internal bore of the arbor has a length, L DCB , and L RMU is greater than L DCB .

20 . The abrasive tool of claim 16 , wherein the mounting plate is removably engaged with the arbor.
