| High Light | CNC Machined Aluminum Turned Parts ，Aluminum Turned Parts Air Rotary Union ，Aluminum Pneumatic Rotary Joint | ||
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.

Besides aluminum alloy multi‑axis compound machining, we support diversified material processing. We can produce rotary joint components in brass, 304/316 stainless steel, carbon steel and engineering plastic POM. Whether you need pneumatic, hydraulic rotary union or other complex multi‑feature mechanical parts, we can realize complex structure processing based on your CAD drawings or samples.
Our service covers drawing review, raw material procurement, CNC compound machining, dimensional inspection and finished‑product packaging. Original mill material certificates can be provided upon request.
Q1: Can you customize this rotary union based on my drawing?
A: Yes, we provide full custom service. Please send your CAD drawing or physical sample for accurate quotation.
Q2: What other materials are available besides 6061 aluminum?
A: We support brass, 304/316 stainless steel, carbon steel, POM and other industrial materials for custom components.
Q3: What tolerance can you achieve for this complex rotary joint part?
A: Standard tolerance ±0.03 mm, tight tolerance down to ±0.01 mm can be achieved by 4‑axis compound machining.
Q4: Can you test the sealing performance of rotary unions before delivery?
A: Sure, sealing test is available upon your requirement. Additional testing cost may apply.
Q5: What is your MOQ for custom CNC rotary union parts?
A: Small‑batch prototype orders are supported. MOQ depends on part complexity, please contact us for detailed offer.
