    • Provided is a method of polishing comprising providing a workpiece, providing a fixed abrasive article, providing conditioning particles, and relatively moving the workpiece and the fixed abrasive article in the presence of the conditioning particles to modify the surface of the workpiece and to condition the fixed abrasive. The fixed abrasive article comprises a substrate having a first surface and a region of abrasive composites distributed on the first surface of the substrate. The abrasive composites include a composite binder and abrasive particles, which may be in abrasive agglomerates together with a matrix material. The abrasive particles are harder than the workpiece. The conditioning particles are sufficient to condition one or more of the composite binder, matrix material, and abrasive agglomerates. The hardness of the conditioning particles is less than the hardness of the workpiece and they do not substantially polish the workpiece.
    • 提供了一种抛光方法,包括提供工件,提供固定的磨料制品,提供调节颗粒,以及在调节颗粒存在下相对移动工件和固定的磨料制品以改变工件的表面并调节固定的 磨料。 固定磨料制品包括具有第一表面和分布在基底的第一表面上的研磨复合物区域的基底。 研磨复合材料包括复合粘合剂和磨料颗粒,其可以与基体材料一起在磨料聚集体中。 磨料颗粒比工件硬。 调理颗粒足以调节一种或多种复合粘合剂,基质材料和研磨团聚体。 调理颗粒的硬度小于工件的硬度,并且它们基本上不抛光工件。

    • Provided is a fixed abrasive article for polishing a workpiece having a hardness comprising (a) a substrate having a first surface and a second surface, (b) a region of abrasive composites distributed on the first surface of the substrate, and (c) a region of conditioning amalgams distributed on the first surface of the substrate. The abrasive composites include a composite binder and abrasive particles of a first hardness, which first hardness is higher than the hardness of the workpiece. The amalgams include an erodible binder and conditioning particles sufficient to condition the composite binder and having a second hardness, which second hardness is less than the hardness of the workpiece and greater than the hardness of the composite binder. Also provided are other abrasive articles, and methods of making them.
    • 提供了一种用于抛光具有硬度的工件的固定磨料制品,所述硬度包括(a)具有第一表面和第二表面的基底,(b)分布在所述基底的第一表面上的磨料复合物区域,以及(c) 分布在基板的第一表面上的调节汞齐的区域。 研磨复合材料包括复合粘合剂和具有第一硬度的磨料颗粒,其第一硬度高于工件的硬度。 所述汞合金包括能够调节所述复合粘合剂并且具有第二硬度的可侵蚀的粘结剂和调理颗粒,所述第二硬度小于所述工件的硬度并且大于所述复合粘合剂的硬度。 还提供了其它磨料制品及其制造方法。
