This pneumatic rotary union is fully manufactured by multi‑axis CNC turning & milling composite machining process. Complex flange hole positions, inner chamber structure and threaded gas port require high‑precision combined machining. Strict process control ensures coaxiality, hole‑position accuracy and sealing matching performance for stable pneumatic rotary transmission.
Challenge: Flange distributed mounting holes, inner sealing groove and side thread connector port need multi‑surface machining; cumulative tolerance risk will cause sealing leakage.
Solution: Adopt 4‑axis CNC composite one‑time forming process, complete flange holes, inner sealing groove and side thread in one clamping. Perform 100‑percent dimensional inspection and sealing test to eliminate tolerance stack‑up risk, guarantee leak‑free operation.
