Precision CNC Machining for Automotive Teams
Cambridge's automotive companies are building the sensors, software, and EV systems that define next-generation vehicles — not stamping body panels. That means their machined parts tend to be low-volume, high-precision prototypes: lidar housings, sensor brackets, battery module frames, and test fixtures. A mislocated bore on a sensor mount throws off an entire calibration rig. 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 Cambridge Automotive Teams
Cambridge automotive programs demand precision, traceability, and speed. We deliver all three with every order.

1–50 piece runsParts for Cambridge Automotive Companies
Engine brackets, drivetrain housings, EV components, and more.
Engine Brackets & Mounts
Engine mounting brackets, accessory mounts, sensor bosses, and structural frames machined from aluminum and steel. Cambridge-area teams often spec 7075-T6 brackets for lightweight EV subframes. Tight bolt-pattern tolerances and thread quality on every part.
Al 6061 & steelDrivetrain Housings & Cases
Transmission housings, differential cases, and gearbox covers machined from aluminum and ductile iron. Cambridge R&D teams prototyping new EV drivetrains need precise bore locations and sealing flanges on first articles.
±0.001" standardEV Battery & Motor Parts
Battery tray structures, motor housings, inverter enclosures, and thermal management plates. We work with several Cambridge EV and battery startups on prototype-to-production motor housings in 6061 and 7075 aluminum.
EV-readySuspension & Steering Parts
Control arm brackets, knuckle components, and steering rack housings. Machined from aluminum and steel with tight bore tolerances for press-fit bearings — common on Cambridge autonomous vehicle test platform builds.
High-strength steelBrake Calipers & Components
Custom brake caliper bodies, bracket adapters, and rotor hats machined from 6061 aluminum and 4140 steel. Cambridge performance shops and EV teams spec tight piston bore fits and hard anodize for track-day durability.
Anodize-readyPrototype Fixtures & Tooling
Assembly jigs, weld fixtures, and inspection fixtures for automotive R&D. Cambridge's university-linked research labs and EV startups order rapid-turn prototype fixtures for functional testing and investor demos.

Motional (Hyundai-Aptiv JV) — Autonomous Vehicle Development
Motional develops Level 4 autonomous driving systems from their Cambridge headquarters. Their engineering teams need precision sensor mounts, lidar housings, and structural test brackets on fast prototype cycles.
Rivian — Software & Systems Engineering Office
Rivian's Cambridge engineering team works on vehicle software, ADAS systems, and EV platform development. Prototype hardware for sensor integration and test rigs flows through local CNC suppliers.
Insulet & iRobot — Hardware Engineering Talent Pool
Cambridge's deep bench of hardware engineers at companies like Insulet and iRobot cross-pollinates into automotive. Many EV and AV startups recruit from this talent base and need local prototype machining support.
Analog Devices — Automotive Sensor & Power ICs
Analog Devices designs automotive-grade sensors, battery management ICs, and signal processing chips from their Wilmington campus. Test fixture and packaging tooling demand flows to precision machine shops.
Built for Automotive Teams
High-volume automotive parts need a shop that gets repeatability right — Cambridge EV and supplier teams trust us for that consistency.
IATF 16949-Ready Documentation
Every automotive order ships with a dimensional inspection report, material cert, and process records structured for IATF 16949 compliance. Cambridge EV and robotics teams get documentation packages ready for investor audits and OEM qualification.
Consistent Run-to-Run Quality
Fixtures and proven programs mean your second order matches your first. Cambridge teams iterating on EV prototypes get consistent results across revision cycles — we lock setups and document every change.
CMM Inspection Included
We verify every critical dimension before shipping. CMM reports accompany every order so your Cambridge QC team or contract manufacturer can move straight to assembly.
Fast Prototype Turnaround
Engineering prototypes in 3 to 7 days. Cambridge startup teams on investor or demo deadlines get priority scheduling — we understand that timelines aren't flexible.
