摘要： An extruded plastic strip contains abrasive grains or minerals embedded homogeneously therein throughout is scored along the machine or extrusion axis direction, such scoring including elliptical or pointed perforations with the long axis or generally pointed ends aligned with the scoring and parallel to the machine or extrusion axis. The preferred plastic material is a 612 nylon, although other plastics may be employed. The material is heat workable, yet relatively stiff and can be used to form a wide variety of power driven abrasive tools such as shown in applicant's prior application Ser. No. 07/471,385 filed Jan. 29, 1990 entitled "Abrasive Tool and Method of Making", now U.S. Pat. No. 5,155,945. The present application also discloses a rotary wheel type tool utilizing the perforated strip, and a method of making that tool using a gel type cyanoacrylate as an adhesive. With the strip of the present invention, rotary wheel tools as well as many other tools can economically be produced. In tool use, the strip fractures along the scoring and perforations to provide a tool having closely packed individual rectangular fingers, each with a major flat side facing the direction of rotation.
摘要翻译：挤出的塑料条含有沿着机器或挤出轴线方向被均匀地嵌入的磨料颗粒或矿物，其中包括椭圆形或尖锐的穿孔，其中长轴线或大致尖端与刻痕对齐并平行于机器或挤出轴线。优选的塑料材料是612尼龙，尽管可以使用其它塑料。该材料是热可加工的，但相对较硬，并且可用于形成各种动力驱动的研磨工具，如申请人先前申请的Ser。 1990年1月29日提交的题为“Abrasive Tool and Method of Making”的美国专利No.07 / 471,385，现为美国专利第5,155,945号。本申请还公开了利用穿孔带的旋转轮式工具，以及使用凝胶型氰基丙烯酸酯作为粘合剂制造该工具的方法。利用本发明的条带，可以经济地生产旋转轮工具以及许多其他工具。在工具使用中，钢带沿着刻痕和穿孔断裂，以提供具有紧密包装的单个矩形手指的工具，每个具有面向旋转方向的主平面。

摘要： Embodiments described herein relate to integrated abrasive (IA) polishing pads, and methods of manufacturing IA polishing pads using, at least in part, surface functionalized abrasive particles in an additive manufacturing process, such as a 3D inkjet printing process. In one embodiment, a method of forming a polishing article includes dispensing a first plurality of droplets of a first precursor, curing the first plurality of droplets to form a first layer comprising a portion of a sub-polishing element, dispensing a second plurality of droplets of the first precursor and a second precursor onto the first layer, and curing the second plurality of droplets to form a second layer comprising portions of the sub-polishing element and portions of a plurality of polishing elements. Here, the second precursor includes functionalized abrasive particles having a polymerizable group chemically bonded to surfaces thereof.

摘要： The present disclosure relates to a method for making a grinding wheel with abrasive surfaces located on an outer diameter of the grinding wheel to provide grinding characteristics of both coarse and fine abrasive textures. The method includes forming on the grinding wheel a coarse abrasive portion located proximate to a first axial end of the outer diameter, a fine abrasive portion located proximate to a second axial end of the outer diameter and a transition band formed at an interface between the abrasive surfaces. The transition band has an abrasive coating with a gradual change in texture from a coarse surface to a fine surface.

摘要： Embodiments of the present disclosure relate to advanced polishing pads with tunable chemical, material and structural properties, and new methods of manufacturing the same. According to one or more embodiments of the disclosure, it has been discovered that a polishing pad with improved properties may be produced by an additive manufacturing process, such as a three-dimensional (3D) printing process. Embodiments of the present disclosure thus may provide an advanced polishing pad that has discrete features and geometries, formed from at least two different materials that include functional polymers, functional oligomers, reactive diluents, addition polymer precursor compounds, catalysts, and curing agents. For example, the advanced polishing pad may be formed from a plurality of polymeric layers, by the automated sequential deposition of at least one polymer precursor composition followed by at least one curing step, wherein each layer may represent at least one polymer composition, and/or regions of different compositions. Embodiments of the disclosure further provide a polishing pad with polymeric layers that may be interpenetrating polymer networks.

摘要： An abrasive rotary tool includes a tool shank a flexible planar section positioned opposite the tool shank. The flexible planar section forms a first abrasive external surface on a first side of the flexible planar section and a second abrasive external surface on a second side of the flexible planar section. The flexible planar section facilitates abrading, corners of a workpiece across multiple angles relative to the axis of rotation for the rotary tool through bending of the flexible planar section when the abrasive external surfaces are applied to a corner of the workpiece.
