This miniature Swiss-turned pin combines a cylindrical shaft with a flat base, creating challenges in maintaining concentricity, surface finish, and dimensional stability on very small diameters. The component is critical in assemblies where precise alignment, minimal play, and smooth mating surfaces are required.
CIXIN utilizes Swiss Turning technology, which allows the workpiece to remain fixed while the tooling moves around it, ensuring high accuracy and minimal deflection on small parts. Sequential turning, fine finishing passes, and strict process control ensure both the shaft diameter and the base remain within tolerance. This process reduces post-processing, burrs, and handling errors, making the component ready for direct assembly.
By combining precise motion control with CIXIN’s expertise in miniature component machining, the service delivers high repeatability, superior surface quality, and reliable functional performance, meeting demanding aerospace, medical, and instrumentation requirements.
