CNC Machining For Precision Actuator Parts: Product Overview
eVTOL landing gear and actuator components represent two distinct but structurally related product families unified by one critical design requirement: the combination of high structural load capacity and minimum mass.
- Impact-load structural analysis as a standard DFM deliverableEvery eVTOL landing gear primary structural component must be designed and machined for the dynamic design landing load.
- Piston rod cylindrical grinding at Ra 0.1μm for seal performanceThe performance of every dynamic seal in eVTOL actuator systems is governed primarily by the piston rod surface finish.
- EMA ball screw housing bore precision for actuator accuracyThe housing bore accuracy (±0.003mm) governs whether the ball screw nut is correctly centered in the actuator housing for designed running clearance.
- TC4 STA primary structural programs for manned flight certificationAll primary structural eVTOL landing gear components are life-limited primary structural parts under proposed FAA AC 21.17-1.
