Finishing medical parts requires very stringent testing and results to ensure that the parts are deburred properly. Titanium stents are inserted into arteries to keep them open. A properly deburred edge and smooth surface finish is absolutely necessary to ensure that the medical part works exactly as expected.
Titanium is a hard metal and is often deburred in a vibratory tumbler with Ceramic Media. The size and shape will depend on the geometry of the part and size of the openings. Adding a medium size grit such as Aluminum Oxide will increase the abrasiveness of the tumbling process and provide a smooth, rounded edge. If embedding of the grit is of concern, using a Ceramic Media that is aluminum oxide free (i.e., KDF Bond) with an addition of Silicon Carbide will also produce excellent results.
