CNC Machining for the Valley That Builds Stealth Bombers
Palmdale is where the B-21 Raider takes shape. Northrop Grumman's Site 4 sits right here, and Lockheed's Skunk Works is minutes away. The Antelope Valley runs on aerospace-grade precision. RivCut is pursuing ITAR registration and built for defense work — weapon system components, optical mounts, tactical enclosures, all machined to mil-spec tolerances with full documentation. If your program office needs traceable parts fast, we're ready to quote today.

Precision CNC Machining for Defense Teams
Defense companies in Palmdale need parts that are exact, traceable, and compliant. A weapon mount that's out of spec affects reliability in the field. We machine aluminum 7075, 4340 steel, and titanium 6Al-4V to tolerances as tight as ±0.0005 inches. We are pursuing ITAR registration and handle controlled technology with proper export controls.
Shop Pursuing ITAR Registration
We are registered with the DDTC under ITAR. Defense and controlled-technology projects are handled by US persons only with proper export procedures.
Mil-Spec Materials
We machine aluminum 7075, 4340 steel, titanium 6Al-4V, and mil-spec alloys with full material certs and heat lot traceability.
Full Traceability
Every part gets a job number with records of material, programs, and operator sign-offs. Your program office can request records at any time.

Why Palmdale Defense Teams Work With RivCut
Union City is in the Bay Area. Palmdale is a five-hour drive south. That means your parts ship same-day via overnight freight and land at your dock before your morning stand-up. No cross-country wait. No East Coast time zone lag.
Pursuing ITAR Registration
We're California-based, which matters for programs running on West Coast schedules. When your mechanical lead calls at 4 PM Pacific to flag a revision, we're still at our machines — not wrapping up for the day in another time zone.
Mil-Spec Documentation
Palmdale runs some of the most security-sensitive defense programs on the planet. B-21 final assembly, Skunk Works advanced development, and continuous flight-test activity at Edwards AFB mean your supply chain has to be airtight. We don't subcontract ITAR work. We don't send controlled drawings offshore. Everything stays in-house, in California, with US persons only.
CMM Inspection Included
We also understand the pace of Antelope Valley defense work. Programs here move fast. An engineering change on Tuesday needs updated hardware by Thursday. Our CNC team turns around revised parts in 3–5 business days for most geometries, and we can discuss expedite timelines for critical-path items. Upload your revised CAD file, and we'll confirm the new quote the same day.
Fast Prototype Turnaround
RivCut isn't a job shop that occasionally touches defense work. Defense and aerospace are core to what we do. You won't be explaining ITAR to us or waiting for a compliance review. We're already there.
