Housing Shaft for Knee Surgery
The stainless steel shaft pictured here, used in orthopedic knee surgery, represents a typical project we have in-shop on a continual basis.
To fabricate this part, we utilized our 9-axis Swiss turning center, which gave us the ability to perform multiple operations simultaneously for the complex contours and intricately angled radii. Our combination of high-tech equipment and master machinists enabled us to maintain dimensional tolerances of ± 0.025″ and angular tolerances of ± 0.5° on this part, which featured dimensions of 2.7559″ in length and 1.0630″ in height. Additional operations consisted of heat treating and passivating for strength and corrosion resistance, as well as grinding and bead blasting to achieve the desired surface finish.
Our in-depth knowledge of the industry and advanced manufacturing and inspection technologies enabled us to cost-effectively fabricate the 30 units in this order in less than 4 weeks.
