    Abstract: Provided are abrasive assemblies and related methods that combine a head portion including an integral abrasive member and a drive portion including a resilient cylindrical mandrel. The abrasive member has a receptacle that is complemental to a working end of the mandrel when both members are relaxed. As the abrasive member engages to, or disengages from, the mandrel, the receptacle resiliently expands and the working end of the mandrel resiliently compresses, each in cooperation with the other. Optionally, the abrasive member is maintained in compression in both directions parallel and perpendicular to the longitudinal axis of the mandrel. Advantageously, these assemblies provide for superior retention and slip resistance, ease-of-use, and high manufacturing tolerances.

    Abstract translation: 提供了研磨组件和相关方法,其组合包括整体磨料构件的头部和包括弹性圆柱形心轴的驱动部。 研磨构件具有当两个构件松弛时与心轴的工作端互补的容器。 当研磨构件与心轴接合或脱离时,容器弹性膨胀,并且心轴的工作端弹性压缩,每个与另一个配合。 可选地,研磨构件在平行于和垂直于心轴的纵向轴线的两个方向上保持压缩。 有利地,这些组件提供优异的保持性和防滑性,易于使用和高制造公差。
