PROBLEM TO BE SOLVED: To provide a method in which an ablation speed (eventually, processing efficiency) is increased while reducing an associated calorific value.SOLUTION: A coating abrasive article 100 contains an abrasive layer 114 fixed to a backing 110. The abrasive layer contains abrasive particles 118 fixed in a first main surface 115 of the backing by at least one kind of bonding agent. A supersize 119 is disposed in at least a portion of the abrasive layer. The coating abrasive article has a melting flow zone 130b adjacent to an edge 132 of the coating abrasive article, and the melting flow zone has the maximum width less than 100 micrometer. Also, the melting flow zone has the maximum height less than 40 micrometer. A method of using an infrared laser for the ablation of the coating abrasive article is also disclosed, and the wavelength of the laser is made to agree with the component of the coating abrasive article. 【課題】付随する発熱量を軽減しながら、アブレーションの速度（ひいては処理効率）を増加させる方法を提供する。【解決手段】被覆研磨物品１００は、裏材１１０に固定された研磨層１１４を含む。研磨層は、少なくとも１種の結合剤によって裏材の第１の主表面１１５に固定された研磨粒子１１８を含む。スーパーサイズ１１９は、研磨層の少なくとも一部に配置される。被覆研磨物品は、被覆研磨物品の縁部１３２に隣接する溶融流れゾーン１３０ｂを有し、この溶融流れゾーンは、１００マイクロメータ未満の最大幅を有し、また、この溶融流れゾーンは、４０マイクロメータ未満の最大高さを有する。被覆研磨物品をアブレーションするために赤外線レーザーを使用する方法もまた開示され、レーザーの波長は、被覆研磨物品の構成要素と一致させられる。【選択図】図１
