Orthopedic Implant Component Polishing Bobs

The precision shops that are providing the mold-making services along with metal and plastic implant manufacturers enjoy our abrasive polishing products. Spartan polishing bobs include the built-in abrasives like silicon carbide, aluminum oxide, or diamond in order to make the light deburring, pre and final polishing faster, along with cleaner and more efficient results. These compounds are basically the impregnated felt bobs that provide the shorter polishing time than the plain felt bobs and the cleaning process.
