This hygienic‑grade filling nozzle valve core is manufactured by mill‑turn composite process. It integrates long slender shaft, tapered flow‑guide section, cross positioning stop and threaded connection. The critical sealing mating surface adopts manual precision grinding to guarantee reliable sealing cooperation with filling nozzle sleeve.
Mill‑turn one‑clamp production completes turning, cross‑milling, boring and threading within single setup. It avoids repeated re‑clamping error, maintains unified coaxial datum, ensures straightness of long slender shaft and consistent sealing profile. Sharp edges are fully broken and burr‑free, well‑suited for high‑frequency reciprocating movement inside liquid filling machinery.

| Feature | Our Capability |
|---|---|
| Composite‑Structure Machining | One‑stop mill‑turn composite processing for long‑shaft filling valve core. One‑clamp completes shaft, cross‑milling, thread and tapered flow‑guide profile, reduces re‑clamping deviation. |
| High‑Precision Control | Unified rotary datum ensures shaft straightness and high coaxiality; manually fine‑ground sealing surface achieves stable sealing performance against nozzle sleeve. |
| Process Difficulty | Long slender shaft tends to deflect during high‑speed turning; tapered sealing surface requires controlled grinding stock; cross‑stop milling needs anti‑vibration cutting strategy. |
| One‑Clamp‑Forming Advantage | Complete turning, cross milling, boring and tapping in single clamping; zero repeated positioning error, stable batch interchangeability for filling equipment assembly. |
| Surface Quality | Burr‑free, sharp corners broken; key sealing surface fine‑ground; hygienic surface meets liquid filling industry requirement. |
