ActOn Case Studies
Traditionally, finishing knee implants at large scale involves mechanical processes like robotised belt polishing or abrasive polishing. These methods work by generating friction to the piece and against a generic abrasive. Those processes, however, tend to present some issues as they can be time consuming and components might need rework or scrapping.
In this case study we discuss about a more cost-efficient solution which improves the surface finish of knee implants and makes them more functional, while increasing their lifespan.
The client is a multinational medical company whose activity revolves around medical device development and manufacturing with strong presence in orthopedic implant manufacturing sector. As this organisation focuses on creating innovative solutions in orthopedics, they needed to:
A batch of samples of cobalt-chrome femoral components were prepared for trials, in different sizes. The aim of the trial is to define the ideal process parameters & steps to reach the final finish, with less process time and lower costs.
The processing time was 60 minutes with a capacity of 24 pieces per batch. The starting average roughness was 0.2 microns. After two steps of abrasive finishing with ceramic and plastic media the final roughness was below 0.05 microns.
