Case studies in the medical industry - Cobalt-chromium-molybdenum prosthetic bone and joint processing


The hip joint consists of the acetabulum, the spherical piece and the metal stem. The joint in a prosthesis is usually made of materials such as cobalt-chromium-molybdenum. Machining prosthetic joints produces small batches, cobalt-chromium is a wear-resistant material and the rounded arc of the spherical surface requires efficient and safe turning operations.


WSS CBN inserts provide stable and efficient machining of cobalt-chromium-molybdenum prosthetic bone and joint cases with a hardness of HRC 35° in the form of turning and continuous finishing. With suitable machine tools and machining parameters, they can last up to 25 pieces.
