Precision CNC Machining for Avionics Teams

Avionics enclosures protect sensitive electronics from vibration, temperature, and electromagnetic interference. A housing with a warped mating surface or a mislocated connector cutout fails EMI testing — sending your schedule back weeks. We machine 6061-T6 and 7075-T6 aluminum enclosures with mating surface flatness to 0.001" over 12 inches, EMI gasket grooves held to ±0.002", and connector positions accurate to ±0.001" true position. Every enclosure ships with CMM inspection and material certs.

1

EMI Shielding Features

We machine gasket grooves, knife-edge flanges, and internal ribs that improve shielding effectiveness. Groove dimensions held to ±0.002" for consistent gasket compression across the mating surface.

2

Precision Connector Cutouts

MIL-DTL-38999 circular connectors, D-sub ports, and custom interface panels — we machine cutout positions to ±0.001" true position with counterbores and anti-rotation features.

3

Matched Set Assemblies

Lid and base halves machined as matched sets with shared datums. Dowel pin holes, gasket grooves, and fastener patterns align perfectly every time. Serial-numbered and shipped together.

What We Machine

MIL-DTL-38999 compatible

Mounting Trays

Avionics bay mounting trays and rack slides machined from aluminum sheet and plate. Quick-release latch features, cable routing channels, and vibration isolation mounting holes. Tight slot widths for edge-card connectors.

Vibration isolation

Heat Sink Enclosures

Combined enclosure and heat sink assemblies with integrated fin arrays machined from solid aluminum billet. Thermal interface pad pockets, internal component shelves, and external cooling fins for passive thermal management.

Integrated thermal management
Avionics Ecosystem

Built for Avionics Programs

Modern aircraft carry dozens of avionics boxes — from flight computers and GPS receivers to tactical radios and radar processors. Each one sits in a custom-machined enclosure designed to withstand vibration, thermal cycling, and electromagnetic interference.

The avionics market is growing fast as aircraft become more connected, more autonomous, and more software-defined. New programs and upgrades drive constant demand for precision-machined enclosures, housings, and connector plates.

Whether you're building prototypes for a next-gen flight management system or production enclosures for a tactical radio, we machine avionics housings with the precision and documentation your program requires.

Collins Aerospace — Avionics Leader

Produces flight management systems, displays, and communication radios for commercial and military aircraft. Every unit needs a precision-machined enclosure for EMI shielding and environmental protection.

L3Harris Technologies — Defense Electronics

Tactical radios, electronic warfare systems, and ISR platforms. L3Harris programs demand ruggedized enclosures with precise connector interfaces and EMI performance.

Honeywell Aerospace — Cockpit Systems

Flight management computers, inertial navigation systems, and weather radar units. Honeywell avionics require precision-machined aluminum enclosures meeting stringent environmental qualification specs.

Garmin Aviation — GA Avionics

General aviation flight displays, GPS units, and autopilot systems. Garmin's avionics lineup relies on compact, precisely machined aluminum housings for cockpit-mounted electronics.

Why RivCut

Built for Avionics Enclosures

EMI shielding, connector precision, and matched assemblies demand a shop that understands avionics.

EMI Gasket Groove Precision

We machine gasket grooves to ±0.002" width and depth for consistent compression across the mating surface. Your enclosure passes EMI testing the first time without gasket rework.

Mating Surface Flatness

We hold 0.001" flatness on lid and base mating surfaces. Proper flatness means proper seal — for EMI, moisture, and environmental protection.

Connector Position Accuracy

Connector cutouts positioned to ±0.001" true position. MIL-DTL-38999, D-sub, and custom connectors fit perfectly without reaming or rework on the assembly floor.

Matched Set Machining

We machine lid and base halves as matched sets using shared fixture datums. Dowel pins, gaskets, and fasteners align perfectly. Shipped together with serial numbers.

How It Works

From File to Part in 3 Steps

Simple, clear, and designed for fast-moving avionics teams.

Step 1

Upload & Quote

Send your STEP or IGES file for your enclosure, housing, or connector plate. Pick your aluminum alloy, quantity, and finish. Our AI gives you a real price right away. We also run a free DFM check on wall thicknesses and EMI features.

Step 2

We Machine & Inspect

Your enclosures run on our CNC mills with optimized toolpaths for pockets, connector cutouts, and gasket grooves. Every order gets CMM inspection on flatness, wall thickness, and connector positions.

Step 3

Ship with Full Docs

Parts ship with dimensional inspection reports, material certs, and AS9100D-aligned paperwork. Everything your avionics team needs for unit qualification and program documentation.

FAQ

Questions About Avionics Enclosures

We primarily machine avionics enclosures from aluminum 6061-T6 and 7075-T6. 6061-T6 is the most common choice for its excellent machinability, corrosion resistance, and compatibility with anodize and Alodine finishes. 7075-T6 is used when higher strength is required. Both are sourced with full mill certs and heat lot traceability.
Yes. We machine EMI gasket grooves, knife-edge flanges for conductive gaskets, and internal rib features that improve shielding effectiveness. We hold groove width and depth to ±0.002 inches for consistent gasket compression. Tell us your shielding spec and we'll confirm the features during our DFM review.
We hold flatness to 0.001 inches over 12 inches on enclosure lid and base mating surfaces. This ensures proper gasket seal and EMI shielding performance. We verify flatness on our CMM and include the measurement in your inspection report.
Yes. We machine circular and rectangular connector cutouts for MIL-DTL-38999, MIL-DTL-26482, and D-sub connectors. We hold cutout position to ±0.002 inches and hole patterns to ±0.001 inches true position. We also machine counterbore features and anti-rotation keyways for connectors.
We offer as-machined (63 Ra or better), anodize Type II and Type III per MIL-A-8625, Alodine (chromate conversion per MIL-DTL-5541), nickel plating for EMI shielding, and bead blast. Most avionics enclosures get Alodine or conductive anodize for grounding and EMI performance.
We routinely machine enclosure walls down to 0.040 inches in aluminum 6061-T6 without distortion. For walls thinner than 0.060 inches, we use light finish passes, climb milling, and strategic work-holding to maintain flatness. We verify wall thickness on our CMM and note any areas of concern during our free DFM review.
Yes. We machine lid and base halves as matched sets. We use the same fixture datums and program origins for both halves to ensure perfect alignment of dowel pin holes, gasket grooves, and connector cutouts. We ship matched sets together with serial numbers.
Most avionics enclosure prototypes ship in 5 to 7 business days after order confirmation. Simple single-piece enclosures can ship in 3 to 4 days on rush. Multi-piece assemblies with matched lids and bases may take 7 to 10 days. Tell us your deadline when you upload — we'll confirm what's achievable.
