Aerospace Parts We Manufacture

CNC Machining Techniques for Aerospace

Xintao supports several CNC machining processes for aerospace-related precision parts, depending on material, geometry, tolerance and production quantity.

5-Axis CNC Machining

For complex aerospace-related brackets, housings, covers and lightweight structural components.

CNC Milling

For aluminum, titanium, stainless steel and PEEK parts with pockets, holes, slots and mounting surfaces.

CNC Turning

For shafts, sleeves, spacers, threaded components and cylindrical precision parts.

Mill-Turn Machining

For cylindrical components with cross holes, flats, grooves, threads and multi-sided features.

Drilling, Tapping & Threading

For precise holes, threaded interfaces and mounting features based on customer drawings.

Materials for Aerospace CNC Parts

Surface Finishes for Aerospace CNC Parts

We provide 30+ surface finishing options for aerospace-related CNC parts. Common finishes include anodizing, hard anodizing, passivation, polishing, sandblasting, black oxide, nickel plating and heat treatment.

As machined	Sand blasting	Polishing /  Mirror Polishing	Anodizing Type  II & III
Standard functional parts with visible machining marks.	Uniform matte texture before anodizing or final finishing.	Smooth or high-gloss surface for stainless steel and aluminum parts.	Improves corrosion resistance and appearance for aluminum parts.
Passivation	Chromate Conversion Coating / SurTec 650	Plating	Powder Coating
Improved corrosion resistance for stainless steel components.	Provides corrosion resistance, electrical conductivity and paint adhesion for aluminum parts.	Nickel, zinc and other plating options for corrosion protection and appearance.	Color, surface protection and durable industrial appearance.

Quality & Inspection Support

• Pre-Production Review: We conduct rigorous analysis of drawings, focusing on critical tolerances, material specifications, and inspection criteria before manufacturing begins.

• Precision Reporting: Full dimensional inspection reports provided for critical features, including bores, threads, and mating surfaces.

• Material Traceability: Certificates (EN 10204 3.1) available upon request for titanium, high-strength aluminum, stainless steel, and PEEK.

• Process & Security: FAI (First Article Inspection) support for new launches; NDA support guaranteed for all confidential projects.
