Dimensional Accuracy:
The dimensional tolerances of high-precision titanium alloy parts are often required to be controlled within 0.005 mm (5 micrometers). For some critical components (e.g., aerospace engine blades, precision sensor assemblies), even nanometer-level accuracy is required. This demands reliance on high-precision machining equipment (such as five-axis machining centers, slow wire-cutting machines, and ultra-precision grinding machines) and real-time online measurement systems (e.g., laser interferometers, coordinate measuring machines) to ensure every step of the machining process is accurately monitored and corrected.

Geometric Tolerances:
Stringent requirements are imposed on geometric errors such as straightness, flatness, and perpendicularity. For example, in the aerospace sector, the flatness of titanium alloy structural components must be controlled within 0.01 mm/100 mm; otherwise, assembly accuracy and overall equipment performance may be compromised.

Surface Quality:
Surface roughness must achieve Ra ≤ 0.02 micrometers to prevent surface defects (e.g., scratches, pores, microcracks) from reducing the part's fatigue strength. Surface treatments (e.g., anodizing, plasma spraying) are often applied after machining, but these processes must not affect dimensional accuracy. Therefore, precise control of process parameters is critical.

Mechanical Properties:
Custom parts must meet specific strength, toughness, and corrosion resistance requirements. For instance, aerospace titanium alloy parts must achieve a tensile strength of ≥ 800 MPa and an impact toughness of ≥ 40 J/cm². This necessitates strict control of heat treatment processes (e.g., solution aging) to avoid material performance degradation due to improper machining temperatures or cooling rates.

Internal Quality:
Non-destructive testing (e.g., ultrasonic inspection, radiographic testing) ensures the absence of internal defects such as inclusions, porosity, or cracks. This is particularly critical for parts used in high-pressure or high-temperature environments (e.g., rocket engine combustion chambers), where internal defects could lead to catastrophic failures.

Consistency and Stability:
For batch customization, each part must exhibit highly consistent performance and precision. This requires standardized processes, automated production lines (to minimize human intervention), and a comprehensive quality traceability system (e.g., blockchain-based recording of full-process data).

Industry-Specific Requirements

Different application fields impose additional specialized requirements for custom high-precision titanium alloy parts:

Aerospace Sector:
Parts must be lightweight, high-strength, and high-temperature resistant (withstanding 300–600°C). They must also comply with aerospace-grade quality certifications (e.g., AS9100) and adhere to strict military or aerospace standards (e.g., GJB, HB standards).

Medical Device Sector:
For titanium alloy parts implanted in the human body (e.g., artificial joints, bone screws), biocompatibility (non-toxicity, corrosion resistance) is essential alongside precision. Machining must be conducted in cleanrooms to avoid contamination.

High-End Equipment Sector:
For precision titanium alloy components in semiconductor equipment, extremely low impurity content (e.g., oxygen content ≤ 0.1%) is required to avoid affecting vacuum environments and ion purity during semiconductor production.
