STRUCTURED ABRASIVE ARTICLE AND METHOD OF MAKING AND USING THE SAME

摘要

A structured abrasive article comprises a backing, a structured abrasive layer affixed to the backing, the structured abrasive layer comprising: a plurality of raised abrasive regions, each raised abrasive region consisting essentially of a close-packed plurality of pyramidal abrasive composites; and a network consisting essentially of close-packed truncated pyramidal abrasive composites, wherein the network continuously abuts and separates the raised abrasive regions from one another. The height of the pyramidal abrasive composites is greater than the height of the truncated pyramidal abrasive composites. Methods of making and using the same are also disclosed.
