Professional CNC Impeller Manufacturing Services

AOOM Technology is a specialized CNC impeller processing manufacturer serving aerospace, automotive, energy, and marine industries worldwide. Our advanced 5-axis simultaneous machining centers produce complex impeller geometries with optimized fluid dynamic profiles for pumps, compressors, and turbines. With extensive experience in high-speed machining of difficult-to-cut alloys such as Inconel and titanium, we deliver impellers that match or exceed original design specifications for hydraulic and aerodynamic efficiency. Our process begins with CAD/CAM simulation of the full 5-axis toolpath, including collision detection and cutter-load optimization, before any metal is cut, ensuring first-piece success on even the most complex blade geometries.

Key Technical Specifications

• Blade profile accuracy: ±0.01mm across full contoured surface with 5-axis simultaneous interpolation
• Materials: Aluminum 7075-T6, Stainless Steel 17-4PH and 316L, Titanium Ti-6Al-4V, Inconel 718, Hastelloy X, and high-strength brass alloys
• CNC impeller processing capacity: outside diameters from 20mm to 600mm; blade heights up to 150mm; hub configurations including shrouded and unshrouded
• Surface finish: Ra 0.8µm on flow surfaces as standard; superfinishing to Ra 0.2µm for enhanced hydraulic efficiency and reduced boundary-layer losses
• In-process CMM inspection with full blade profile geometry reports, 5-axis touch probing, and structured-light 3D scanning verification
• Dynamic balancing up to G2.5 grade per ISO 1940 and overspeed burst containment spin testing upon request
• Optional post-processing: abrasive flow machining (AFM) for edge blending, shot peening for fatigue enhancement, and thermal barrier coating

Applications

Our CNC machined impellers are critical components in centrifugal and axial flow pumps for industrial chemical processing, water treatment, and marine propulsion systems; turbocharger compressor and turbine wheels for automotive diesel engines and aerospace auxiliary power units; compressor wheels for HVAC centrifugal chillers, refrigeration systems, and industrial turbo-expanders; turbine rotors for micro gas-turbine power generation and waste-heat recovery organic Rankine cycle systems; and mixed-flow and diagonal impellers for oil and gas pipeline boosting stations, produced in corrosion-resistant alloys for sour-gas service environments. Each impeller undergoes rigorous CFD validation against customer performance curves and full 5-axis in-process probing to verify that every blade profile, leading-edge radius, and trailing-edge thickness meets the designed aerodynamic or hydraulic performance targets. Completed parts are shipped with full dimensional reports, material certifications, and balance documentation.

Quality Assurance

Every cnc impeller manufacturing order from AOOM Technology is manufactured under a comprehensive quality management system certified to ISO 9001:2015. We employ coordinate measuring machines (CMM) for full dimensional verification, First Article Inspection (FAI) per AS9102 for new production runs, and in-process statistical process control (SPC) to maintain consistent quality across all batches. Material certifications, dimensional reports, and compliance documentation are provided with every shipment.
