Abstract
This invention relates to improved abrading elements for honing tools containing a plurality of abrading elements, which may be rotated and/or radially moved in contact with the surface to be honed, the improvement comprising an abrading element embodying an abrasive article, having an abrading face and an opposite, substantially flat, attachment face, in a molded plastic, unitary, support structure, the unitary support structure having a substantially flat support face to which the attachment face of the abrasive article attaches, the support face having voids therein such that from about 70 to 90 percent of the surface area of the attachment face of the abrasive article is in contact with the support face and the support face being resiliently supported by a triangular truss support bridge intimately molded therewith.
Claims22
An abrading element comprising a preformed abrasive article having an abrading face and an opposite attachment face, in a molded plastic unitary support structure, said unitary support structure having a flat support face to which the attachment face of the abrasive article attaches and said support face having voids therein such that from about 70 to about 90 percent of the surface area of the attachment face of said abrasive article is in contact with said support face and from about 10 to about 30 percent of said surface area is opposite said voids, and said support face being resiliently supported by a triangular truss support bridge intimately molded therewith.
An abrading element comprising a substantially rectangular abrading article having an abrading face and an opposite attachment face adhesively attached to the support face of an injection molded plastic unitary support structure, said support face being substantially flat having three beveled slotted depressions therein such that from about 10 to about 30 percent of the surface area of the attachment face of said abrasive article is opposite said slots and said support face having an intimately molded perpendicular support lip extending from the trailing edge of said support face, sad support lip being adhesively attached to the trailing side of said abrasive article and said support face being resiliently supported by a triangular truss support bridge intimately molded therewith.
An abrading element support structure for use in combination with an abrasive article comprising a molded unitary plastic body having a support face adapted for attachment of the abrasive article and an opposite lower face having intimately molded therebetween, a triangular truss support bridge which provides resilient support for said support face, said support face having intimately molded thereto at the trailing edge, a perpendicular support lip.
