This single head flange step locating pin is professionally produced by high-precision Swiss Machining process, exclusively designed for micro and ultra-tolerance precision positioning scenarios. Manufactured from solid 304 stainless steel bar, the entire product adopts one-time integral Swiss CNC machining forming, completing round head molding, limit flange shaping and thin guide shaft processing in one single pass.
The advanced Swiss machining technology eliminates secondary clamping errors, delivering exceptional concentricity, smooth surface finish and consistent dimensional accuracy that ordinary CNC turning cannot match. All edges and corners are precisely chamfered and fully deburred to remove all flying burrs and sharp edges. After ultrasonic degreasing and deep cleaning, the pins are processed with electrolytic mirror polishing for flawless surface texture and excellent anti-oxidation performance.
As a specialized Swiss CNC machining manufacturer, we not only supply standard electrolytic polished guide pins, but also provide full custom service and OEM customized machining. We process custom step locating studs according to customer drawings and samples, supporting non-standard size, special structure and high-precision customization for precision fixtures, automation equipment, electronic devices and precision mechanical assemblies.
