在基材中形成凹部之方法、磨轮及外壳;METHOD OF FORMING A RECESS IN A SUBSTRATE, ABRASIVE WHEEL, AND COVER

摘要

本发明提供一种在基材表面中形成凹部之方法，其包括：提供研磨物件，其包含沿支撑部件之周边表面安置之结构化研磨部件；使该结构化研磨层与基材表面以摩擦方式接触；使该结构化研磨层相对于该基材表面纵向前移；及使该研磨物件或该基材中之至少一者相对于另一者绕垂直于该基材表面之旋转轴旋转，以使得该结构化研磨层与该基材表面维持接触且研磨该基材表面。该结构化研磨部件包含结构化研磨层，该结构化研磨层包含固定至衬底之成形研磨复合物，其中该衬底接近该支撑部件。该等成形研磨复合物包含保持在黏合剂材料中之研磨颗粒。本发明亦提供一种包含安置于支撑轮之周边表面上之结构化研磨部件的磨轮及包括对接圆柱通道之球状凹部的显示器外壳。; and rotating at least one of the abrasive article or the substrate relative to the other around a rotational axis perpendicular to the surface of the substrate such that the structured abrasive layer maintains contact with and abrades the surface of the substrate. The structured abrasive member comprises a structured abrasive layer comprising shaped abrasive composites secured to a backing, wherein the backing is proximate to the support member. The shaped abrasive composites comprise abrasive particles retained in a binder material. The present disclosure also provides an abrasive wheel comprises a structured abrasive member disposed on a peripheral surface of a support wheel and display covers including a spherically concave recess abutting a cylindrical passage.
