ABSTRACT:
The invention provides an abrasive article having a surface having a machine direction axis and opposite side edges, each side edge being parallel to the machine direction axis and a plurality of parallel rows of abrasive composites in fixed position on the surface, each row being aligned at an angle with a side edge which is neither 0.degree. nor 90.degree., and methods for making such an abrasive article. The abrasive article of this invention also can be used in any convenient form including an endless belt. The resulting abrasive article provides a high rate of cut, long belt life, and a relatively fine surface finish on the workpiece being abraded.
