CNC Machined Rotor Shaft

As a professional CNC machining manufacturer in China, BestPro can make CNC Machined Rotor Shafts for engineers and needing high accuracy, close tolerance and certified quality documentation. Rotating shaft assemblies are important for turbines, propellers, tail rotors and so on. Even just slight variances in runout or straightness will impact vibration, NVH and performance.

Materials & Treatments For Aerospace Rotor Shafts

Ti-6Al-4V (Grade 5 Titanium) – this is also an aerospace grade which can boast of its high strength-to-weight-ratio, as well as corrosion and fatigue resistance.

Aerospace alloy steel (4140, 42CrMo) – good strength and thermal stability for high load rotor shafts.

Shafts may be of forged or billet if stiffness, fatigue life and thermal concerns dictate. We will supply full QC-documentation, including material certificates, dimensional check and runout readings.

Examples of surface finishing and precision processes are:
Precision grinding
Heat treatment where applicable
Nitriding or phosphating (for steel)
Bead blasting or polishing
Processes are strategically sequenced to minimize straightness and concentricity loss in thin wall or long shaft components to promote assured reliable performance for aerospace rotor applications.
