CNC Machining for the Valley That Builds Stealth Bombers
Palmdale's Antelope Valley is where the B-21 Raider takes shape at Northrop Grumman's Site 4. Skunk Works runs advanced programs just down the road. Edwards AFB tests what gets built here. The aerospace companies in this corridor need machined parts that meet flight-critical standards — not close, not almost. RivCut machines structural components, avionics hardware, and engine parts to ±0.0005" with full CMM documentation and material traceability. We ship from Union City to Palmdale in one to two days. Your quality team gets what they need. Your program timeline stays on track.

Precision CNC Machining for Aerospace Teams
Aerospace companies in Palmdale need parts that are exact, traceable, and documented. A structural bracket that's off by 0.003 inches can create an unsafe condition. We machine aluminum 7075, titanium 6Al-4V, and Inconel 718 to tolerances as tight as ±0.0005 inches. Every order ships with CMM inspection reports, material certs, and documentation your quality team can use.
Flight-Critical Materials
We source and machine aluminum 7075-T6, titanium 6Al-4V, and Inconel 718 — all with full material certs and heat lot traceability.
Tight Tolerances
We hold ±0.001" on general features and ±0.0005" on critical bores and mating surfaces. Every part is CMM verified before shipping.
Full Documentation
Dimensional inspection reports, material certs, first article inspection — whatever your AS9100D-aligned quality plan requires.
What We Machine for Palmdale Aerospace Teams
Palmdale aerospace programs demand precision, traceability, and speed. We deliver all three with every order.
Aircraft Structural Components
We machine wing ribs, fuselage brackets, spar fittings, and bulkhead clips from aluminum 7075-T6 and 2024-T3. These parts hold tolerances of ±0.001" on general features and ±0.0005" on critical bores and mating surfaces. Every part ships with a CMM inspection report.
AS9100D qualityEngine & Turbine Parts
Stealth platforms and advanced development aircraft need avionics boxes that fit exact envelopes. We machine 6061-T6 and 7075-T6 enclosures with precise pocket depths, tight RF gasket surfaces, and connector cutouts held to print.
Exotic alloysAvionics & Electronics Enclosures
High-heat zones on propulsion systems and exhaust structures need Ti-6Al-4V and Inconel 718. We have experience cutting both. You get full heat lot traceability and material certs that your receiving inspection team can verify against the mill report.
EMI-shieldedLanding Gear & Actuation Parts
Advanced development programs in Palmdale move fast and change often. We turn around prototype parts in three to five business days. First Article Inspection reports follow AS9102 format so your quality team can approve quickly.
Safety-criticalSatellite & Space Hardware
Flight control surfaces and landing gear actuation systems need machined components held to ±0.0005" on bore diameters. We machine these from 4340 steel and 17-4 PH stainless with surface finishes to 32 Ra or better.
Space-qualifiedAerospace R&D Prototypes
Rapid prototype machining for aircraft and space programs. 1 to 50 pieces with full material certs, CMM reports, and AS9100D-aligned documentation.
