  • Publication number: 20220395962
    Abstract: The disclosure is generally directed to a method of manufacturing an abrasive rotary tool using a molded elastic layer. A mold includes a cavity with a peripheral surface. An abrasive sheet is positioned so that a working surface of the abrasive sheet is positioned along at least a portion of the peripheral surface. A spindle is positioned within the mold to create a region between the spindle and the abrasive sheet. An elastomeric precursor material is injected into the region and solidified to form an elastic layer. As a result, the elastic layer is in direct contact with at least a portion of the opposed surface of the abrasive sheet and at least a portion of the exterior surface of the spindle. In this way, an abrasive rotary tool may be manufactured without using adhesive layers and/or fastening means.

  • Publication number: 20210347012
    Abstract: The disclosure provides abrasive rotary tools with enhanced adhesion of an abrasive layer. Exemplary abrasive rotary tools include a securing element configured to secure an abrasive layer to an abrasive rotary tool. The securing element may be positioned over a portion of the abrasive layer, such as a tab or end, such that repeated forces on the abrasive layer do not decouple the abrasive layer from the rotary tool. In this way, an abrasive rotary tool may maintain a contact surface integrity through repeated use for extended life of the rotary tool.

  • Publication number: 20210214658
    Abstract: The present invention is a cleaning article including a substrate and organic abrasive particles dispersed on the substrate. The organic abrasive particles have a Mohs hardness of between about 2.0 and about 5.0. The cleaning article cleans greater than about 0.9 panels in 1,000 cycles and has a Schieffer Scratch performance rating of less than or equal to about 3.5.

  • Patent number: 11040429
    Abstract: An abrasive rotary tool includes a tool shank defining an axis of rotation for the rotary tool, and an abrasive external working surface. The abrasive external working surface includes a resin, and a plurality of porous ceramic abrasive composites dispersed in the resin, the porous ceramic abrasive composites including individual abrasive particles dispersed in a porous ceramic matrix. At least a portion of the porous ceramic matrix comprises glassy ceramic material. A ratio of the average porous ceramic abrasive composite size to the average individual abrasive particle size is no greater than 15 to 1.

  • Publication number: 20210114171
    Abstract: The present disclosure provides abrasive articles that include an abrasive layer having a contact surface, a first layer coupled to the abrasive layer, and a second layer coupled to the first layer. The first layer is configured to provide contact pressure to the abrasive layer, such as through a higher hardness than the second layer. The second layer is configured to provide conformability to the abrasive layer, such as through a higher compressibility than the first layer. The resulting abrasive articles may exert a consistent contact pressure against a substrate with increased conformability around the substrate, reduced hysteresis, improved removal rate consistency, and/or improved lifetime over abrasive articles that do not use the multiple layer construction described above.

  • Patent number: 10906156
    Abstract: 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.

  • Patent number: 10265826
    Abstract: A method of forming a recess in a surface of a substrate includes: providing an abrasive article comprising a structured abrasive member disposed along a peripheral surface of a support member, frictionally contacting the structured abrasive layer with a surface of a substrate, longitudinally advancing the structured abrasive layer relative to the surface of the substrate; 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.

  • Publication number: 20160101499
    Abstract: An assembly may include a substrate defining at least one recess and a component located adjacent to the recess and attached to the substrate. In some examples, the recess may be formed by frictionally contacting a structured abrasive layer of an abrasive article with a surface of the substrate, longitudinally advancing the structured abrasive layer relative to the surface of the substrate, and rotating the substrate around a rotational axis substantially perpendicular to the surface of the substrate such that the structured abrasive layer maintains contact with and abrades the surface of the substrate thereby forming the recess therein. In some examples, the recess may be formed in the substrate after the component is attached to the substrate. Moreover, the recess may be formed without using added loose abrasive particles or abrasive slurry.
