Where Silicon Valley's Hardware Corridor Meets Automotive Precision
Sunnyvale sits at the center of one of the densest hardware engineering clusters on Earth. Your automotive team shares zip codes with Lockheed Martin's satellite facility and Intuitive Surgical's robotics campus. Those neighbors set a high bar for part quality. RivCut machines automotive components to that same standard — tight tolerances, full documentation, fast turnaround — from our shop in Union City, 30 minutes up the Dumbarton Bridge corridor. Whether you're building EV drivetrain hardware or prototype suspension geometry for a Silicon Valley startup, we hold ±0.0005" and ship same-week.

Precision CNC Machining for Automotive Teams
Sunnyvale automotive companies are building the sensor stacks and ADAS hardware that will define how cars drive themselves. These are not high-volume stamped parts — they're low-volume, high-precision sensor housings, calibration fixtures, and structural prototypes where a tenth of a thousandth matters. A lidar mount that shifts after thermal cycling blinds the vehicle. We machine aluminum, steel, and stainless to tolerances as tight as ±0.0005 inches with full documentation.
Automotive Materials
We machine aluminum 6061/7075, 4140 steel, stainless, and engineering plastics — all with full material certs and traceability on request.
Tight Tolerances
We hold ±0.001" on general features and ±0.0005" on critical bores, journals, and sealing surfaces. Every part CMM verified.
Full Documentation
Dimensional inspection reports, material certs, and first article documentation — whatever your IATF 16949-aligned quality plan requires.
What We Machine for Sunnyvale Automotive Teams
Sunnyvale automotive programs demand precision, traceability, and speed. We deliver all three with every order.
Engine & Powertrain Parts
We machine motor housings, inverter enclosures, and battery tray brackets in 6061 and 7075 aluminum. Thermal management features — cooling channels, press-fit bores for heat inserts — are held to ±0.001" or tighter. We machine stainless and 4140 steel for high-load structural brackets in the same setup.
Tight bore toleranceBrake System Components
Sunnyvale automotive teams pack a lot of electronics into tight spaces. We machine camera mounts, LiDAR brackets, and control unit enclosures with tight positional tolerances on mounting features. Tapped holes, counterbores, and precision dowel pins are standard.
Safety-criticalSuspension Components
Prototype suspension uprights, control arm brackets, and steering rack mounts are a regular part of our work. We machine these in billet aluminum and 4140 steel to match your CAD exactly — no interpretation, no shortcuts.
Bearing-fit precisionTransmission Parts
Every critical feature is CMM verified before your parts ship. You get a dimensional report with every order — no extra charge, no asking twice.

Intuitive Surgical, maker of the da Vinci robotic surgery system, is headquartered in Sunnyvale. Their engineering culture — tight tolerances, validated processes, full traceability — is another benchmark that shapes local supplier expectations.
Waymo (Alphabet) — Sunnyvale AV Headquarters
Waymo's Sunnyvale campus is the nerve center of its autonomous driving program. Custom lidar mounts, radar housings, and calibration fixtures must hold position to sub-thousandth accuracy across thousands of road-test miles.
Mercedes-Benz R&D North America — Sunnyvale
Mercedes-Benz runs its North American R&D and autonomous driving research from Sunnyvale. Prototype sensor brackets, structural test components, and interior mechanism parts flow through local CNC suppliers.
Luminar Technologies — Lidar Manufacturing
Luminar designs and manufactures automotive-grade lidar sensors in the Bay Area. Their precision optical housings and mounting interfaces require machining tolerances measured in tenths of a thousandth.
Cepton Technologies — 3D Lidar Systems
Cepton develops lidar solutions for ADAS and autonomous vehicles from their San Jose campus near Sunnyvale. Custom sensor housings and integration brackets are machined in small batches on fast prototype cycles.
Why Sunnyvale Automotive Teams Use RivCut
We're in Union City. That puts us about 18 miles from your office via the Dumbarton Bridge corridor — no crossing the Bay on a congested freeway, no sending parts to a shop in the Central Valley and waiting a week. You can drop off a raw billet in the morning and talk to the machinist who's running your job by afternoon.
IATF 16949-Ready Documentation
Sunnyvale's automotive engineers work on accelerated development cycles. Your program timeline doesn't pause because a supplier is in a different time zone. RivCut operates on Pacific Time, same as you. When you email a revised drawing at 8 a.m., we see it at 8 a.m.
Consistent Run-to-Run Quality
Your neighbors — Lockheed Martin, Intuitive Surgical — have raised the quality expectations for every supplier in this zip code. We machine to those same standards. Our shop runs modern CNC equipment with in-process inspection and final CMM verification. We document everything.
CMM Inspection Included
We also understand that Sunnyvale automotive teams often share suppliers with their aerospace and robotics neighbors. If your team is cross-functional — pulling engineers from the semiconductor or defense world — we speak that language too. GD&T callouts, first article reports, material certs: we treat these as standard, not premium add-ons.
Fast Prototype Turnaround
Shipping is straightforward. Parts go out via UPS or FedEx from Union City. Standard lead times run 5–7 business days. Rush jobs can ship in 3. You're never waiting on a cross-country freight carrier.
