Definitions

  • an additional functional layer may be provided.
  • a functional layer may be applied in addition to, or as, a supersize coat.
  • the functional layer may be deposited in a pattern, as indicated in block 252, which may be the same or different from any abrasive particle pattern layer. Additionally, in some embodiments, the functional layer is applied in an even coating, as indicated in block 254. For example, it may be desired to have grinding aid, for example, evenly deposited on an article. Additionally, the functional layer may also include grinding aids and/or anti -loading materials.
  • a supersize coat may be applied in a pattern to indicate a manufacturer or grade of the abrasive article.
  • FEPA grade designations include F4, F5, F6, F7, F8, F10, F12, F14, F16, F20, F22, F24, F30, F36, F40, F46, F54, F60, F70, F80, F90, F100, F120, F150, F180, F220, F230, F240, F280, F320, F360, F400, F500, F600, F800, F1000, F1200, F1500, F2000, P12, P16, P20, P24, P30, P36, P40, P50, P60, P80, P100, P120, P150, P180, P220, P240, P280, P320, P360, P400, P500, P600, P800, P1000, P1200, P1500, P2000, P12, P16, P20, P24, P30, P36, P40, P50, P60, P80, P100, P120, P150, P180, P220, P240

  • the surface coating may prevent the shaped abrasive particle from capping.
  • Capping is the term to describe the phenomenon where metal particles from the workpiece being abraded become welded to the tops of the crushed abrasive particles. Surface coatings to perform the above functions are known to those of skill in the art.
  • the article may be implemented such that the make layer comprises the patterned coating, and wherein the size layer comprises an even coating such that, for a portion of the backing, the size layer directly contacts the backing.
  • the method may be implemented such that the abrasive particles are magnetically coated.
