Detroit Builds Engines. Now Its Medical Teams Need Parts Built the Same Way.
Detroit's 49 medical device companies operate in a city that invented precision manufacturing. But automotive tooling shops don't hold the tolerances your surgical instruments or orthopedic implants require. RivCut does. We machine titanium, PEEK, and 316L stainless to ±0.001" with full CMM inspection reports — the kind of documentation your FDA quality plan actually needs. Detroit's 1,624 medical device workers deserve a machining partner who understands both precision and compliance. That's us.

Precision CNC Machining for Medical Device Teams
Medical device companies in Detroit need parts that are exact, clean, and fully documented. A surgical instrument that's 0.003 inches off can fail in the field. We machine titanium, 316L stainless, PEEK, and medical-grade aluminum to tolerances as tight as ±0.0005 inches. Every medical order ships with a CMM inspection report, material certs, and documentation your quality team can use.
Biocompatible Materials
We source and machine titanium Grade 23 ELI, 316L stainless, and PEEK — all with full material certs and traceability.
Tight Tolerances
We hold ±0.001" on general features and ±0.0005" on critical bores, tapers, and mating surfaces. Every part is CMM verified.
Full Documentation
Dimensional inspection reports, material certs, passivation certs — whatever your quality plan requires, we provide it.
What We Machine for Detroit Medical Device Teams
Detroit medical device programs demand precision, traceability, and speed. We deliver all three with every order.
Surgical Instruments
We machine stainless steel forceps, retractors, and trocar housings to tight edge-break specs. Surface finishes matter here. We hold Ra 32 or better on contact surfaces and can go to Ra 16 for instruments that require smoother finish for sterilization cycles.
Ra 16 finishOrthopedic Implant Components
Titanium Grade 23 ELI and cobalt-chrome are standard here. We machine bone screw prototypes, trial implants, and cutting guides. Tolerances on bore diameters run ±0.0005". Every implant component ships with material certs and traceability back to raw stock.
BiocompatibleDiagnostic Equipment Parts
Detroit's imaging and diagnostic companies need enclosures that are tight, clean, and repeatable. We machine medical-grade 6061 and 7075 aluminum housings with threaded inserts, EMI shielding grooves, and tight flatness specs for gasket seating.
±0.001" precisionDrug Delivery Device Parts
Detroit has a growing rehab tech cluster tied partly to its auto injury and occupational health networks. We machine PEEK and titanium brackets, joint interfaces, and actuator housings used in prosthetic and assistive device prototypes.

Why Detroit Medical Teams Work With RivCut
Detroit has no shortage of CNC shops. The metro area runs thousands of machine tools built around Ford and GM production schedules. But automotive tolerances and medical tolerances are not the same thing. A valve body and a surgical instrument require completely different process controls, documentation, and material handling. Most Detroit shops aren't set up for that. RivCut is.
Medical-Grade Documentation
We're based in Union City, California. Parts ship to Detroit in two to three business days via ground freight. For urgent prototype needs, overnight air gets you parts the next morning. Detroit operates on Eastern Time. Our engineering team in California is available from 6 a.m. Pacific, which means you have coverage starting at 9 a.m. your time — the full Detroit workday.
Ultra-Clean Surface Finishes
When you upload a CAD file, you get AI-generated pricing immediately. A real engineer reviews your design for manufacturability the same day. If your part has a feature that will drive up cost or cause tolerance stack problems, we flag it before you cut a purchase order.
Full Part Traceability
Detroit's medical device companies often run lean engineering teams. You don't have a full DFM department sitting next to the design team. We fill that gap. We've machined implant trials, imaging brackets, and surgical tool prototypes for teams that needed fast turnaround without sacrificing the FDA-traceable documentation their quality plans require.
Same-Week R&D Turnaround
We're not an automotive shop trying to pivot into medical. Medical precision is what we do.
