[0123] 1. Advantages of cutting through the back side

[0124] Several abrasive articles were prepared using conventional make / size coating techniques. There was no superadhesive in these tests and no attachment system on the backing. with CO 2 The laser converts the abrasive article into a disc with internal porosity.

[0125] For each test, an abrasive article was prepared with CO 2 An abrasive article is made by first laser cutting the internal pores through the back side (in accordance with the disclosed invention), and an abrasive article is made by laser cutting the internal pores through the front side (ie, the abrasive coating side). Pores of six different configurations were prepared. Figure 8 A graph of performance results is shown. Abrasive articles that are transformed (eg, cut) through the back side first do not have ridges, while abrasive articles that cut through the front side first do have ridges.

[0126] From Figure 8 As seen in , for about 10 and...

Abstract

Abrasive articles, and methods of making abrasive articles that include a supersize coating or component, such as one configured to inhibit the collection of dust and / or swarf on the abrasive coating. The supersize component can be applied to the abrasive coating after converting the abrasive article with a laser or other conversion mechanism, whether non-contact or mechanical contact. In some embodiments, no fresh or exposed abrasive or backing surfaces exist; that is, the supersize component covers all surfaces.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application Serial No. 60 / 893,003, filed March 5, 2007, entitled Laser Cut Abrasive Article, and Methods, the entire disclosure of which is incorporated by reference way incorporated into this article. technical field [0003] The present invention relates to abrasive articles, methods of making such abrasive articles, and methods of using such abrasive articles. Background technique [0004] Abrasive products have been used for grinding and polishing workpiece surfaces for more than one hundred years. These applications range from high cutting of workpieces such as wood and metal to fine polishing of optics, optical fibers and computer read / write heads. Generally, abrasive articles comprise a plurality of abrasive grains bonded together (eg, bonded abrasives or grinding wheels) or to a backing (eg, coated abrasives). For coated abrasives, the abrasive particles ...
