1. Appearance: 

The overall color is silver-gray titanium alloy with a high-gloss mirror finish achieved through ultra-precision machining. The 

structure is an integrated, complex cavity component, including a large main cavity, irregularly shaped side cavities, and multiple sets of positioning 

holes/threaded holes. The edges are smoothly transitioned, and the hole positions are regularly distributed, showcasing the design characteristics 

of high-precision assembly.

2. Material: 

The base material is TC4 (Ti-6Al-4V) titanium alloy: possessing low density (only 60% of that of steel), high strength (tensile strength 

exceeding 900MPa), and excellent corrosion resistance (resistant to high temperature/acid and alkali environments), while also exhibiting good 

machinability. It is a commonly used material for core structural components in high-end equipment.

3. Manufacturing Process

5-axis CNC milling + Electrical Discharge Machining (EDM): Complex internal cavities and irregularly shaped holes require multi-axis simultaneous 

milling for rough machining, followed by precision forming via EDM (ensuring internal cavity accuracy);

Ultra-precision polishing: Surface roughness Ra≤0.8μm, improving sealing and wear resistance;

Precision hole control: Positioning hole tolerance IT5, threaded hole tolerance IT6, meeting the requirements of modular high-precision assembly.

4. Applications

This part is a core component of high-end precision fluid control/power systems.

Aerospace: Fuel distribution valve body for aircraft engines, integrated chamber blocks for hydraulic systems;
