Precision CNC Machining for Automotive Teams
San Jose automotive companies are engineering the future of transportation — EV powertrains, autonomous sensors, and battery systems that didn't exist five years ago. These aren't catalog parts. A motor housing for a next-gen EV drivetrain has to dissipate heat, seal against coolant, and hold bearing bores to half a thousandth. 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.

Tesla — Fremont Factory & Engineering
Tesla's Fremont assembly plant produces Model S, 3, X, and Y vehicles. The engineering team's prototype and tooling needs ripple through the entire South Bay supplier ecosystem, from motor housings to battery tray fixtures.
Lucid Motors — Newark HQ & Powertrain R&D
Lucid designs its class-leading EV drivetrain in Newark, just north of San Jose. Prototype inverter housings, motor end caps, and thermal management components require tight-tolerance CNC machining on fast timelines.
Waymo (Alphabet) — Autonomous Vehicle Hardware
Waymo's self-driving technology relies on custom sensor arrays with precision-machined mounting brackets, calibration fixtures, and structural housings that must hold position to sub-thousandth accuracy.
Zoox (Amazon) — Purpose-Built Autonomous Vehicles
Zoox designs fully autonomous vehicles from their Foster City campus near San Jose. Their hardware teams need custom structural castings, sensor integration brackets, and prototype chassis components.
Built for Automotive Teams
San Jose AV and EV teams need a machining partner that scales from 10-unit prototypes to 100-unit fleet builds with zero variation.
IATF 16949-Ready Documentation
Every automotive order ships with a dimensional inspection report, material cert, and process records. San Jose AV and sensor teams get traceability documentation that satisfies both automotive OEM requirements and hardware investor due diligence.
Consistent Run-to-Run Quality
Fixtures and proven programs mean your second order matches your first. San Jose AV teams scaling from 10-unit test fleets to 100-unit deployments get identical parts every time.
CMM Inspection Included
We verify every critical dimension before shipping. CMM reports confirm sensor mount datums and optical surface tolerances — critical for San Jose lidar and camera integration teams.
Fast Prototype Turnaround
Engineering prototypes in 3 to 7 days. San Jose AV teams iterating weekly on sensor mounts and test fixtures get parts on a cadence that matches your sprint cycles.
