A precision machine shop in the foothills outside Sacramento. Small enough to know every part on the floor. Equipped to run the work the big shops won't bother with — and won't get right anyway.
Kelly Manufacturing has been precision-machining parts for high-stakes industries from Auburn, California since 1988. We're a family business — small enough to know every part that hits the floor, equipped enough to run multi-axis Haas machining, in-house inspection, and the full materials envelope your program calls for.
We started as a job shop. Thirty-eight years later, we've stayed one. Some shops chased scale; we chased the work that demands precision. The customers who trust us aren't shopping for the cheapest quote — they're shopping for the part that comes back right the first time.
If you've ever fought a vendor who treated your tolerances as suggestions, you already know why we exist.
No certification badge tells you what working with a shop is actually like. These do.
If something on your drawing will cost more than you expect, we tell you before the PO — not after.
Tolerances on the print are the spec. Not a suggestion, not a target. The job either holds them or it doesn't ship.
If we owe you an answer, you get it that day — not next week. Engineering questions don't wait.
Every part runs through QC before it leaves. We don't ship work we haven't checked.
We've spent 38 years machining for industries where a sloppy part is a recall, a lawsuit, or worse.
Bracketry, housings, fixturing, and precision components for aerospace OEMs and Tier-1 suppliers. Tolerances held, paperwork in order, parts that pass FAI the first time.
Surgical instrument components, device housings, and machined parts for medical equipment. Repeatability matters here — if part 1 is right, part 10,000 needs to be too.
Precision-machined components for wafer manufacturing tooling. Tight tolerances on tough materials — and lead times that don't slow down a fab.
Machined parts for environmental control systems where consistent fit and function keep clean rooms, labs, and facilities running.
Forty minutes northeast of Sacramento, in the Sierra foothills. Close enough to Bay Area programs to ship overnight; far enough out to keep our overhead honest and our pricing competitive.
