Power Your Next Engine with Precision-Engineered Propulsion Components

CNC Works AI is AS9100D certified for aerospace quality management and ISO 9001:2015 certified for general quality management. Our special processes—including heat treatment, welding, and non-destructive testing—are NADCAP-accredited. We provide full material certifications, First Article Inspection (FAI) reports per AS9102, CMM dimensional data, and complete traceability documentation with every shipment.

Yes. We specialize in difficult-to-machine aerospace superalloys including Inconel 718, Waspaloy, Ti-6Al-4V, and Hastelloy X. Our 5-axis centers with through-spindle coolant and ceramic tooling handle these materials at optimal speeds. For large impellers up to 430mm diameter, we maintain 0.02mm concentricity and 0.06mm blade alignment using FEA-optimized cutting parameters. Discuss your impeller requirements.

According to our CNC machining knowledge base, monoblock impellers require complex free-form machining with narrow blade spacing. We use a multi-stage approach: roughing, semi-finishing, and finishing, with finite element analysis optimizing cutting parameters to predict and minimize blade deformation. VT simulation verifies toolpaths before execution, and probe calibration ensures coordinate system alignment throughout the process.

According to our CNC machining knowledge base, post-treatment deformation is addressed through aging heat treatment and cryogenic stabilization to release internal stresses before surface treatment. We apply a uniform 0.5 mm finishing allowance during roughing, then perform final compensation machining after hard anodizing to ensure flatness, parallelism, and critical dimensions remain within tolerance.

For precision-critical turbine blade features, CNC Works AI achieves ±0.001mm (±0.00004") on root radii and platform surfaces. Standard aerospace tolerance is ±0.005mm (±0.0002"). Surface finishes of Ra 0.8μm are maintained on blade airfoils. Every production lot is inspected on CMM with full dimensional reports provided.

Every propulsion shipment includes material certifications with heat numbers, First Article Inspection (FAI) reports per AS9102, CMM dimensional inspection data, XRF chemical analysis results, ultrasonic testing reports, and a Certificate of Conformance (CoC). RoHS/REACH compliance certificates and special process certifications (NADCAP) are provided as required by your engine program.

Standard propulsion prototypes ship in 5–7 business days with full material certs and dimensional reports. Our case study demonstrates completing an AL7075-T6 impeller (194mm diameter, 12 blades) from process design to delivery within two weeks. Rush service is available in 48–72 hours for urgent validation projects. Get a lead time estimate.

Yes. Our facility is equipped for everything from single-piece blade prototypes to high-volume production runs of 100,000+ units. We use quick-change tooling, automated pallet systems, and high-repeatability custom fixturing to maintain efficiency at scale without sacrificing precision. Whether you need 5 blades for engine testing or 5,000 for a commercial program, our process scales with your demand. Request volume pricing.

Yes. We can reverse-engineer legacy or obsolete propulsion components from samples, drawings, or scan data. Our engineering team produces CAD models and manufacturing drawings compliant with your engine program requirements. Full FAI and dimensional validation ensures replacement parts meet or exceed original specifications. Upload your sample or drawing.
