Orthopedic Implant Polishing Tools

Surface Polishing Products for Orthopedic Implantable Components & Major Medical Manufactured Products

Spartan Felt Company custom manufactures polishing bobs, wheels, and pads to accommodate the precision needs of the medical device manufacturing industry. Precision machine shops that provide mold-making services as well as metal and plastic implant manufactures have a need for abrasive polishing products.

Micro-finishing and Polishing of Titanium, Cobalt Chromium, Stainless Steel, and their alloys, present challenges, because the surface of these metals become malleable under force, a property termed “ductility”. Smearing or galling can occur, which compromise the quality of the finish.  Polishing of these materials require well-designed abrasive tools and process control of pressure and temperature. Spartan has experience in tool and process design to meet your Ra specifications, including mirror finishes.

Spartan Polishing Bobs incorporate built-in abrasives such as aluminum oxide, silicon carbide, or diamond to make light deburring, pre and final polishing faster, cleaner and more efficient. These compound impregnated felt bobs provide shorter polishing time than plain felt bobs and a cleaner process. Abrasive size, concentration and bulk hardness are strictly controlled resulting in consistent product from lot-to-lot.
