ABSTRACT:
An abrasive tool includes a rotatable hub from which extends a bundle of plastic abrasive monofilaments. The bundle has a high filament count and each filament includes a substantial amount of abrasive uniformly entrained therein. After the bundle is secured to the hub, the tool is placed in a mold completely enclosing at least the projecting bundle and a foamable elastomer is injected into the mold to produce a light density cellular matrix bond encapsulating the filaments. The preferred plastic for the plastic monofilaments is nylon 6-12 and the preferred elastomer is a low density (2-20 lbs/cu/ft) polyurethane. The cellular matrix bond for the preferred applications upon wear does not produce a liquid phase at even high tool pressures. Radially extending enlarged coolant passages may be formed during the encapsulation and injection process step. The tool may be in disk, cup or twisted stem form.
