Built for the Kendall Square Supply Chain
Waltham's life sciences corridor runs from Kendall Square through the Seaport, and it sets a brutal standard for part quality. Your device can't wait on a slow machine shop. RivCut machines surgical instruments, implant components, and diagnostic housings to ±0.0005" tolerances — with the CMM reports and material traceability your FDA submission demands. We work with Waltham-area medical teams from first prototype through production runs, and every order ships with documentation your quality engineer can sign off on immediately.

Precision CNC Machining for Medical Device Teams
Medical device companies in Waltham 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 Waltham Medical Device Teams
Waltham medical device programs demand precision, traceability, and speed. We deliver all three with every order.
Surgical Instruments
We machine cannulas, retractors, forceps handles, and trocar housings from 316L stainless steel. Surface finishes reach Ra 16 µin or better for cleanroom-ready parts. Passivation certs ship with every order.
Ra 16 finishOrthopedic Implant Components
We work in Titanium Grade 23 ELI — the alloy Waltham orthopedic and spine companies rely on. Tolerances on critical bore diameters hold at ±0.0005". Every billet comes with a full material cert and heat number traceability.
BiocompatibleDiagnostic Equipment Parts
Kendall Square biotech startups building PCR cartridges, microfluidic devices, and handheld diagnostics need tight-tolerance plastic and aluminum enclosures. We machine medical-grade PEEK, Delrin, and 6061-T6 aluminum with the dimensional consistency your FDA design validation requires.
±0.001" precisionDrug Delivery Device Parts
Waltham is home to surgical robotics developers pushing articulating arm components and end-effector tooling. We machine the small, complex titanium and stainless parts these systems require, holding true position to ±0.001" across multi-axis features.
FDA-readyLab & Analytical Equipment
Whether your team at a Cambridge startup needs three prototype iterations before an investor demo or a Seaport-based scale-up needs 500 production units, we scale with you. Rapid prototyping turnaround runs 3–5 business days. Production pricing drops with volume.
Ultra-preciseMedical Device Prototypes
Rapid prototypes for 510(k) and PMA submissions. 1 to 50 pieces with full material traceability and inspection documentation.

Why Waltham Medical Teams Work with RivCut
Waltham engineers ask a fair question: why send parts to a machine shop in Union City, California? Here's the honest answer.
Medical-Grade Documentation
Waltham's local machine shop market is tight. With 10,924 medical device workers competing for capacity at a small pool of qualified shops, lead times stretch and prices climb. RivCut gives you a real alternative with no capacity crunch.
