Improved Performance

    The Burr Abrador Deburring Disc sets the standard for performance and value in abrasive filament disc technology. The Burr Abrador disc's superior performance is due to the construction of tightly tufted or bundled filaments set into a rigid backing. The Performance gain is do to four factors.
    The performance gain is due to four factors. First, the filaments in resin cast deburring discs are typically set individually or uniformly throughout the backing. This results in spacing much like a pine tree forest where the filaments are free to flex and bend without the sides rubbing against each other. Because of this the individual filaments do not get maximum support from each other. The tightly bundled fibers in the Burr Abrador disc are in contact with each other which yields maximum support resulting in reduced stresses upon individual fibers. Second, on resin cast deburring discs a meniscus forms at the base of the fiber which focuses stress at this point which can cause fatigue failure causing filaments to "lay over" or brake off and end up strewn about the production area. In the Burr Abrador disc the filaments are mounted as a tightly bundled group in a common hole which eliminates high stress concentrations at the base of the filaments and the resulting fatigue failure. Third, on resin cast deburring discs the resin tends to wick up the base of individual filament groups. This creates a stiff base of unusable filament. This unused filament is evidenced as rigid stumps on the used resin cast disc. Fourth, resin cast backings are flexible and often out of flatness. When the filaments come into contact with the part to be deburred the contact pressure must deflect the backing against the backing plate to create the correct engagement. The excess engagement is repeated each revolution of the disc and results in excessive filament wear. The Burr Abrador design uses a rigid engineered plywood backing that presents the filaments consistently each and every time, resulting in consistent engagement and uniform wear.
     In summary the Burr Abrador Deburring Disc sets the standard for performance and value in abrasive filament disc technology. The Burr Abrador disc's superior performance is due to the construction of tightly tufted or bundled filaments set into a rigid backing.
