The Surface Finish Paradox: Why 4 Ra Isn’t Good Enough for High-End Medical CNC Parts
The pursuit of a perfectly smooth surface on medical CNC parts often introduces hidden risks like smeared metal, embedded contaminants, and compromised biocompatibility. Drawing from a decade of machining critical implants and surgical instruments, this article reveals why targeting a specific surface finish profile—not just a low Ra value—is the true mark of expertise. Learn a data-backed strategy to achieve functional, repeatable surfaces that pass validation on the first try.
