2. 双主轴同步加工技术：采用双主轴同步加工工艺，正面与背面工序同步执行，既保证了六角法兰端面与内孔轴线的垂直度和同轴度，又大幅提升加工效率，满足航空液压接头大批量交付需求。

    

3. 17-4PH沉淀硬化不锈钢材料控制：基材选用17-4PH沉淀硬化不锈钢，经过固溶+时效热处理达到H900强度等级，兼具高强度与优良耐蚀性，满足航空液压系统在高压力、高频率工况下的长期可靠运行要求。

    

4. 钝化表面处理工艺：接头成品经钝化处理后形成致密氧化膜，显著提升耐盐雾腐蚀性能，适应航空液压系统在海洋大气、高湿度等严苛环境中的长期使用场景。

    

5. O型圈密封槽精密加工：O型圈密封槽的尺寸精度与表面质量直接决定液压系统的密封可靠性。走心机纵切加工保证槽底及槽侧面的尺寸公差稳定在±0.005mm以内，表面粗糙度达Ra0.4–Ra0.8，确保O型圈装配后的密封效果。

    

6. 60余台进口设备集群化量产：公司拥有60余台西铁城Citizen、津上Tsugami、斯大Star进口走心机，形成规模化设备集群，日产能达50万件，在保障单件一致性的同时实现航空液压管路接头的高效批量交付。

    

典型应用场景

1. 航空液压系统快接接头：用于飞机液压管路中需要频繁拆装的快速连接节点，六角法兰结构便于工具操作，O型圈密封槽保证多次插拔后的密封可靠性。

    

2. 液压管路过渡接头：在液压系统中连接不同管径或不同走向的管路，多台阶过渡结构实现管路的平稳转向与密封衔接。

    

3. 航空航天流体控制元件：应用于航空液压伺服系统、燃油分配系统等流体控制回路中，精密内孔与内外螺纹保证流体通道的通径精度与连接强度。

    

4. 地面保障设备液压连接：用于飞机地面维护、检测设备中的液压管路连接，17-4PH不锈钢的高强度与钝化处理的耐腐蚀性保证地面设备在户外复杂环境下的使用寿命。

Aviation Hydraulic Conduit Fitting — Precision CNC Swiss Machined Component for Aviation Hydraulic Systems

Aviation hydraulic conduit fittings are critical precision connection elements in aircraft hydraulic systems, responsible for high-pressure hydraulic fluid transfer and sealing. Kunshan Tudasyn Electronic Technology Co., Ltd., founded in 1998 with nearly 30 years of dedicated experience in precision Swiss-type CNC machining, manufactures these fittings from 17-4PH precipitation hardening stainless steel. Utilizing over 60 imported Swiss-type lathes (Citizen, Tsugami, Star) with turn-mill compound machining and dual-spindle synchronous processing, we complete all complex features — hex flanges, multi-step OD profiles, O-ring grooves, internal and external threads, and precision bores — in a single clamping setup, delivering reliable and high-integrity connection solutions for aviation hydraulic applications.

Key Specifications

Swiss Machining Process Advantages

1. Single-Setup Complete Machining: Hex flanges, multi-step transitions, O-ring sealing grooves, internal/external threads, and precision bores are all completed in one clamping on Swiss-type lathes through turn-mill compound machining, eliminating coaxiality deviation from secondary setups and ensuring high-precision alignment between the hex flange and bore.

    

2. Dual-Spindle Synchronous Machining: Front and rear operations are executed simultaneously via dual-spindle synchronization, guaranteeing perpendicularity and coaxiality between the hex flange face and bore axis while significantly boosting production efficiency for high-volume aviation fitting delivery.

    

3. 17-4PH Precipitation Hardening Stainless Steel Material Control: The base material undergoes solution treatment and aging heat treatment to achieve H900 strength grade, combining high strength with excellent corrosion resistance for sustained reliable operation under high-pressure, high-frequency aviation hydraulic conditions.

    

4. Passivation Surface Treatment: Finished fittings undergo passivation to form a dense oxide film, significantly enhancing salt spray corrosion resistance for long-term service in demanding environments such as marine atmospheres and high-humidity conditions.

    

5. Precision O-Ring Groove Machining: The dimensional accuracy and surface quality of O-ring sealing grooves directly determine hydraulic sealing reliability. Swiss-type turning maintains groove dimensional tolerance within ±0.005mm with surface roughness of Ra0.4–Ra0.8, ensuring effective O-ring sealing after assembly.

    

6. Cluster Production with 60+ Imported Machines: Our fleet of over 60 Citizen, Tsugami, and Star Swiss-type lathes enables scalable cluster production with a daily capacity of 500,000 pieces, ensuring both individual consistency and efficient batch delivery of aviation hydraulic conduit fittings.

    

Typical Applications

1. Aviation Hydraulic Quick-Connect Fittings: Used in aircraft hydraulic lines requiring frequent connection and disconnection; hex flange design enables easy tool engagement while O-ring grooves ensure sealing integrity after repeated mating cycles.

    

2. Hydraulic Conduit Transition Fittings: Connecting different pipe diameters or routing directions in hydraulic systems; multi-step transition profiles provide smooth directional changes with reliable sealing.

    

3. Aerospace Fluid Control Components: Applied in aviation hydraulic servo systems, fuel distribution circuits, and other fluid control loops where precision bores and threads ensure flow passage accuracy and connection strength.

    

4. Ground Support Equipment Hydraulic Connections: Used in aircraft ground maintenance and testing equipment hydraulic lines; 17-4PH stainless steel strength combined with passivation treatment ensures service life in complex outdoor environments.
