Abstract PROBLEM TO BE SOLVED: To provide an abrasive article which has a pattern of openings, the pattern being a non-uniform distribution pattern.SOLUTION: An abrasive article comprises a coated abrasive having a plurality of apertures arranged in a non-uniform distribution pattern, where the pattern is spiral or phyllotactic and in particular a pattern described by the Vogel equation. Also provided is a back-up pad having a spiral or phyllotactic pattern of air flow paths, e.g., in the form of open channels. The back-up pad can be specifically adapted to correspond to the abrasive article having the non-uniform distribution pattern. Alternatively, the back-up pad can be used in conjunction with conventional perforated coated abrasives. The abrasive article having the non-uniform distribution pattern of the apertures and the back-up pad can be used together as an abrasive system. 【課題】開口部のパターンを有し、当該パターンが非均一な分布パターンである研磨物品を提供する。【解決手段】非均一分布パターンに配置された複数のアパーチャを有する被覆研磨材であって:パターンは、螺旋または葉序であり、特にフォーゲル式によって説明されるパターンである、研磨物品。また、提供されるのは、螺旋または葉序パターンのエアフロー経路(オープンなチャンネルの形態等)を有するバックアップパッドである。バックアップパッドは、具体的には、非均一分布パターンを有する研磨物品と対応するように構成されてよい。あるいは、バックアップパッドは、穴が突き通った従来の被覆研磨材と共に、用いられ得る。アパーチャおよびバックアップパッドの非均一分布パターンを有する研磨物品は、研磨系として一緒に用いられてよい。【選択図】図1
