CNC Machining Techniques for Aerospace
Mossuun 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.

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