Abstract

The invention provides an abrasive article with an integral dust collection system. The abrasive article comprises a porous abrasive layer with openings, a first filter media with channels, a second filter media, and an attachment interface layer. The openings of the porous abrasive layer cooperate with the channels to allow the flow of particles from the abrasive surface to the second filter media.

Description

technical field [0001] The present invention generally relates to an abrasive article. More particularly, the present invention relates to abrasive articles having an integrated dust collection system. [0002] Background technique [0003] Abrasive articles are used in industries where grinding, grinding and polishing applications are performed. Abrasives come in a variety of sizes and shapes, such as ribbons, disks, and flakes. [0004] Generally, when abrasive articles are employed in the form of "sheet articles" (ie, disks and sheets), support plates are used to mount or attach the abrasive article to the abrasive tool. One type of support sheet has a plurality of dust collection holes connected by a series of grooves. The dust collection holes are often connected to a vacuum source to help control the accumulation of swarf on the abrasive surface of the abrasive article. It is known to remove chips, dust and debris from abrasive surfaces to improve the performance o...
