Objective
A medical device manufacturer in the Boston, MA region sought to develop a finishing process capable of producing a high-quality mirror finish on a cobalt chrome partial implant component. The objective was to achieve a consistent surface finish while maintaining the part’s geometry and supporting production efficiency.
| Part Description | Partial Implant |
| Industry | Medical/Pharmaceutical |
| Fabrication Method | CNC Machined |
| Material | Cobalt Chrome |
| Process Type | Surface Preparation, Polish, Superpolish/Ultrapolish |
| Equipment Type | Centrifugal Barrel Finisher / Harperizer, Centrifugal Disc Finisher |
Solution
Bel Air developed a polishing process for a cobalt chrome partial implant component using centrifugal barrel finishing / harperizing technologies. The process was designed to produce a high-quality mirror finish while maintaining part geometry and surface integrity.
The component was processed with specialized media and compounds selected to refine the surface, reduce visible irregularities, and create a more uniform polished appearance. This controlled finishing approach helped simplify the polishing operation and reduce the amount of manual polishing required while supporting a more consistent result from part to part.
