High Precision CNC Machining
Tight tolerances, tough materials, clean finishes — done right, every time. With 15+ years behind the controls, we deliver parts you can trust from prototype to production.
Why engineers send us the parts
other shops won’t take
FJM Manufacturing LLC is a precision machining shop in Nashua, New Hampshire, run by a trained Tool and Die Maker. We machine custom parts to tolerances as tight as ±0.0001″ in aluminum, stainless, titanium, tool steels and engineering plastics — from a single prototype to ongoing production batches — and manage finishing, plating and heat treatment so parts arrive complete.
Tolerances to ±0.0001″
On critical features, proven across multiple medical device contracts.
No minimum order
One piece is a real job. Prototypes, one-offs and repair parts welcome.
No drawing? No problem
3D scanning and reverse engineering — we work from your sample part.
Parts arrive finished
Anodizing, plating, heat treatment and passivation managed for you.
Every part inspected
100% inspection against print before it ships. Never sampled.

Years of Experience
Precision CNC Machining driven by Expertise.
With over 15 years of hands-on machining experience, FJM Manufacturing delivers parts that meet the tolerances, finishes, and consistency your project demands. We dial in machining time, setups, and toolpaths to keep jobs efficient while maintaining accuracy across every run.
Every component goes through a controlled machining and inspection process to ensure reliable quality, whether it’s a one-off prototype or a full production order. We make sure your parts hit the tight specs you require – clean surface finishes, accurate geometry, and repeatable results — and we’ll help refine designs for better manufacturability when needed.
Fast lead times, optimized cycle times, and dependable communication make FJM a partner you can trust for on-spec parts, every time.
