C-Axis Single-Setup Blade Bore Angular Pitch
All blade bores in an eVTOL propeller hub — 2, 3, 4, 5, or 6 blades — are drilled and reamed in one C-axis indexed MAZAK mill-turn program from one chucking without table repositioning.

Why CNCPioneer for CNC Propeller Machining?
Coordinate geometry, material, finishing and inspection around the part's intended function.
Pitch Bearing Seat Concentricity ±0.003mm Single-Setup
eVTOL propulsion components have compound-angle blade attachment interfaces, non-orthogonal bearing seat arrangements, and asymmetric structural geometries requiring 5-axis simultaneous machining for all critical features from one datum reference.
5-Axis Compound Hub Geometry Machining
Review assembly datums, angled features and thin-wall geometry and functional requirements before defining the process.
Blade Grip Mass Matching as Production Standard
CNCPioneer verifies every blade grip to ±1g against the matched-set mean mass , and every propeller hub against design model mass ±1g, on calibrated precision balance recorded per serial number.
