ABSTRACT:
A honing tool characterized in one form by an elongated rectangular cup element or holder having a bottom interior surface, a bundle of closely packed relatively short discrete generally parallel abrasive containing filaments secured in the holder, and a layer of instant gel adhesive securing all of the filaments at one end face of the bundle to the bottom interior surface of the holder. To make such a honing tool, a measured bundle of uniformly closely packed nonwoven, generally parallel discrete filaments is formed. A holder is supported and a measured amount of gel adhesive is placed in the bottom interior of the holder so that a layer of such adhesive completely covers the bottom of the interior of the holder. The bundle is then promptly driven into the holder so that all of the filaments at one end of the bundle are in contact with the adhesive prior to the curing of the adhesive. The adhesive is then cured. In another form a rectangular bundle of abrasive containing strips is formed, each having a slit or scored lateral edge. The plastic strips may be formed into bundles by ultrasonic welding through the unslit or unscored root portions of each strip. The bundle is driven into the holder to be secured by the gel adhesive in the same manner. In either form there is produced a rectangular or oblong honing tool which is provided with relatively short fingers closely packed not only within the holder but also at the working face. The improved tool has a somewhat soft or flexible working face as compared to a conventional honing stone or clad steel tool and will not contaminate the surface being honed. The tool provides an improved surface topography whether used as a finish hone or in a tertiary operation.
