This ball pin component features a cylindrical shaft with an integrated spherical head, requiring high concentricity, surface smoothness, and micron-level dimensional control. Swiss Turning technology allows the workpiece to remain stationary while the cutting tool moves around it, achieving precision on both cylindrical and spherical features in a single setup.
Sequential roughing, semi-finishing, and finishing passes, combined with specialized tooling and fixturing, ensure that the shaft diameter, ball diameter, and surface finish meet exacting standards. Edge finishing and deburring guarantee the component is ready for direct assembly into medical devices, reducing post-processing and ensuring functional reliability.
The component demonstrates Swiss Turning’s capability to produce miniature, high-accuracy parts with smooth surfaces and consistent repeatability for demanding medical applications.
