UAV structures live on a knife edge: every gram of airframe is a gram of payload or flight time, yet the same frame must survive hard landings and vibration spectra that would crack consumer hardware. CNC machining from billet is how serious drone programs square that circle.
What we fly-ready: center frames and folded-quad plates; motor mounts and arm tubes with integrated clamp interfaces; gimbal and camera cages; battery bays with thermal management; avionics trays and EMI-aware enclosures; fixed-wing spar fittings and control-surface hinges.
Mass engineering, not just machining: our DFM pass proposes pocketing strategies that cut mass 20–30% versus your baseline without dropping below fatigue margins — wall-thickness maps, FEA-informed rib placement and stress-relief features come back with the quote, free.
Vibration and fatigue discipline: 7075-T6 for high-load fittings, 6061 for general structure; sharp-corner radii specified by default to kill stress risers; anodize (Type II/III) chosen for the environment — hard coat where carbon-fiber contact or abrasion lives.
Program-scale readiness: from 5-piece flight-test sets to tens of thousands of frames per year. First articles include CMM reports; PPAP-style documentation available when your program feeds automotive or aerospace-adjacent customers.
Pocketing strategies return with the quote — 20–30% mass savings proposed before you cut metal.
Corner radii and grain-direction-aware fixturing specified by default; stress risers engineered out.
5-piece validation sets and 50k/year programs run on identical fixturing and CAM.
From aerospace-grade aluminum to medical-certified engineering plastics, our in-house CNC machining centers work a broad range of metals and plastics under one roof.
