气动接头芯子 / Pneumatic Fitting Core Insert
气动接头芯子
气动接头芯子是工业气动系统与传感器件中的核心密封与导向部件。昆山图达讯电子科技有限公司采用优质H62黄铜为基材，依托高精度走心机纵切与车铣复合工艺，为各类快速气动接头、电磁阀及管接头提供微米级精密加工服务。H62黄铜优异的自润滑性能与切削加工性，使其在频繁插拔的气动配合中表现出卓越的耐磨性与气密稳定性。
针对气动芯子内锥面密封要求高、O型圈槽位置度严苛的加工难点，图达讯采用双主轴同步加工技术，在一次装夹中完成内锥车削、O型圈槽切割与外圆精车。这种“走心机一体成型”工艺不仅彻底消除了二次装夹带来的同轴度误差，更确保了芯子在高压气流环境下的零泄漏表现。

Pneumatic Fitting Core Insert
The pneumatic fitting core insert is a critical sealing and guiding component in industrial pneumatic systems and sensor devices. Kunshan Tudasyn Electronic Technology Co., Ltd. utilizes premium H62 brass as the base material, relying on high-precision Swiss-type CNC sliding headstock turning and mill-turn combined processes to provide micron-level precision machining for various quick pneumatic fittings, solenoid valves, and tube fittings. The excellent self-lubricating properties and machinability of H62 brass ensure outstanding wear resistance and airtight stability in frequent plug-and-pull pneumatic mating.
Addressing the machining challenges of strict inner cone sealing requirements and tight O-ring groove positional tolerances, Tudasyn employs dual-spindle synchronous machining technology. The inner cone turning, O-ring groove cutting, and outer diameter precision turning are completed in a single clamping setup. This "one-stop Swiss-type CNC forming" process completely eliminates coaxiality errors caused by secondary clamping, ensuring zero-leakage performance of the core insert in high-pressure airflow environments.

Features & Swiss-Type CNC Advantages
- Dual-Spindle One-Stop Machining for Ultimate Coaxiality: Utilizing imported Swiss-type CNC dual-spindle synchronous opposite machining, the inner cone, O-ring groove, and OD are completed continuously in one clamping. This completely avoids secondary clamping errors, ensuring extremely high coaxiality between all steps and sealing surfaces.
- Micron-Level Tolerance Control for Superior Airtightness: Precision turning of the inner cone achieves a ±0.005mm (IT6) tolerance grade. Combined with a low surface roughness of Ra0.8-Ra1.6, it ensures a perfect fit with O-rings or valve bodies, meeting the strict leak-proof requirements of high-pressure pneumatic systems.
- O-Ring Groove Precision Optimization for Extended Seal Life: Specialized process optimization for the width, depth, and bottom surface roughness of the O-ring groove prevents the seal from extrusion deformation or abnormal wear during assembly and high-pressure operation, significantly improving the overall service life of the fitting.
- H62 Brass Base Material Combined with Nickel Plating: H62 brass features inherent excellent self-lubrication, ideal for frequent friction mating of pneumatic components. The uniform nickel plating on the surface further enhances oxidation resistance and corrosion protection, adapting to complex industrial environments.
Typical Applications
- Quick Pneumatic Fitting Core Inserts: Serving as the core locking and sealing component of quick fittings, ensuring rapid plug-and-pull and stable airtightness of air tubes under high pressure.
- PU/PA Tube Fitting Guide Cores: Providing precise guidance and support in plastic air tube fittings, preventing the hose from folding or failing to seal during insertion.
- Solenoid Valve Air Inlets: Used at the air intake control end of pneumatic solenoid valves, ensuring precise airflow guidance and reliable dynamic sealing during spool actuation.
- Industrial Automation Pneumatic Control Components: Widely applied in various pneumatic cylinders, pneumatic fixtures, and air circuit distribution modules of automated production lines.
