Millwright Works is a precision CNC machining and tooling shop that turns billet aluminum, hardened steel, and titanium into parts that pass inspection the first time. Five-axis mills, live-tool lathes, a climate-controlled metrology lab, and machinists who have been chasing tenths since before the apprentices were born. Send a print, get a part you can torque into a real assembly.
Parts off these spindles fly, hold pressure, and carry load for
A shop is only as honest as the gear holding the tool. Ours runs in a temperature-stabilized building so the iron doesn't grow on a warm afternoon, and every spindle traces back to the same calibrated reference. No part leaves on a machine we wouldn't run our own work through.
DMG MORI and Haas five-axis mills cut compound geometry in a single setup — impellers, manifolds, turbine housings — so the tolerance stack never compounds across three fixtures and two operators.
Citizen Swiss lathes turn long, slender shafts and connectors down to 1mm diameter with no chatter and no taper, milling flats and cross-holes complete before the bar even parts off.
We machine 62 HRC tool steel after hardening, not before, so the geometry you drew is the geometry you get — dies, molds, and punches finished to a polish, not left to a grinder to fix.
Submerged wire and ram EDM burn sharp internal corners, keyways, and cavities that no end mill can reach, holding ±0.0002" through inch-thick carbide without a hint of tool pressure.
Most jobs that go wrong went wrong before a chip ever flew — a misread callout, a material that won't hold the geometry, a quote that hid the setup. We close those gaps up front, on the phone, with a machinist who has cut the part you're describing.
A manufacturing engineer opens your print or STEP file the same day, flags anything ambiguous in the GD&T, and gets you on the phone before quoting — not after the bar is on the lathe.
You get one number with the tolerance, the finish, and the inspection spelled out line by line. No setup surprise buried in the invoice, no portal you have to fight to read a price.
We write the CAM, simulate the toolpath against the model, and cut a first article before the production lot moves — so the off dimension shows up on part one, not part four hundred.
The job runs on reserved capacity in a 68°F building, on machines that all trace to one calibrated datum, with the same operator owning it bar to box.
Critical features are probed on a Zeiss CMM and the report ships in the crate — actuals beside nominals, lot number on the cert, traceable from raw bar to the part in your hand.
Numbers we measure, not numbers we market.
Anyone can cut metal. The difference shows up at the inspection bench — in whether the dimension on the drawing matches the dimension on the part, and whether you can prove where every gram of that material came from. Here, you can.
A Zeiss coordinate measuring machine probes critical features against your model in a 68°F lab. The dimensional report ships with the parts — actuals next to nominals, not a green checkmark and a promise.
Before a production lot moves, one part goes through full AS9102 first-article inspection. We catch the off dimension on part one, not on part four hundred sitting in your receiving dock.
Every billet ships with a mill certificate, and we carry the heat-lot number from raw bar to finished good. When an auditor asks where the titanium came from, the answer is one line on the cert, not a shrug.
Bead blast, anodize, black oxide, passivation, or a mirror polish to Ra 4 — specified on the traveler, verified with a profilometer, and matched run to run so part nine looks like part one.
Every tapped and single-point thread is checked with go/no-go gauges and logged. A bolt that won't seat costs you a teardown in the field; a thread caught at the bench costs us thirty seconds.
Every part below began as a customer drawing and left as a finished, inspected good. Names sit under NDA — the material, the tolerance, and the inspection are exactly as we ran them on the floor.
A single-setup aerospace manifold with internal runners and twelve mating ports, machined complete on the five-axis, CMM-mapped on every bore, and shipped with full AS9102 paperwork to a flight-hardware program.
A progressive stamping die machined after heat-treat to a mirror finish, sinker-EDM'd at the sharp corners, and matched to its punch within two tenths so the press tool ran a million hits without a regrind.
A pressure-rated valve body for a directional-drilling tool, single-point threaded to API spec, passivated, and proof-tested with a traceable cert from heat lot to serialized part for an energy customer.
An articulating laparoscopic jaw turned and milled complete on the Swiss lathe, electropolished to a biocompatible finish, and gauged feature-by-feature for a Class II medical device first build.
A custom anti-vibration boring bar with an internal coolant channel and a brazed insert pocket cut by submerged wire EDM, balanced and certified for a high-volume automotive line that had run out of catalog tooling.
A thin-wall harmonic-drive housing held flat under 0.0003" of total runout across a 200-unit production run, hard-anodized and lot-stamped, replacing an overseas supplier that was eight weeks out and drifting on size.
“We used to receive parts and re-inspect a hundred percent because the last shop drifted. Two years with Millwright and we sample. Their CMM report matches ours every single time — that trust took a decade to find and a week to confirm.”
“I sent a 62-Rockwell die that two shops said had to be ground after machining. Millwright hard-milled it to print, EDM'd the corners, and it ran a million hits before its first regrind. They do the hard work other shops quote away.”
“Our overseas supplier was eight weeks out and slowly going oversize. Millwright held three tenths of runout across two hundred housings, lot-stamped every one, and we cut the lead time to nine days. The line never stopped again.”
No portal games, no setup surprise on the invoice. Send a drawing, talk to a machinist, and get a real number with the tolerance, the finish, and the inspection spelled out before a single chip flies.
First articles, fit checks, and proof-of-concept builds.
Repeat parts at tolerance, run after run.
Aerospace, medical, and energy work that has to prove itself.
Repeatably to ±0.0001" on turned and milled features, and ±0.0002" through inch-thick carbide on the wire EDM. We hold it because the building is climate-controlled to 68°F, every machine traces to one calibrated datum, and we measure on a Zeiss CMM rather than trusting the spindle readout. If a critical dimension reads out of spec, we recut it free.
Aluminum and stainless every day, plus titanium, Inconel, tool steels hard-milled up to 62 HRC, tungsten carbide on the EDM, and engineering plastics like PEEK and Delrin. If you're unsure whether a material will hold your geometry, send the print — a machinist will tell you before you commit, not after the bar is on the lathe.
Yes. The shop is AS9100D and ISO 9001 certified, with an ISO 13485 quality system for medical builds. We run AS9102 first-article inspection, supply full PPAP and FAI packages, and welcome customer and source inspection on the floor. Every flight or implant-adjacent part ships with the paperwork to back it up.
Prototypes and first articles typically ship in five to ten business days depending on material and finishing. Production lots run against reserved machine capacity on a schedule we commit to in writing. We'd rather quote you an honest three weeks than promise a Friday we both know is a fiction — overpromised dates are how parts end up late and trust ends up gone.
A STEP or solid model gets us started, but for anything with a tolerance that matters we want a dimensioned print or a GD&T drawing so we machine to your intent, not our guess. Send what you have. If the callouts are ambiguous, a manufacturing engineer flags it and gets you on the phone before we cut, not after.
Email a drawing or a model and a machinist — not a chatbot — reviews it the same day. You'll get a real quote with the tolerance, the finish, and the inspection spelled out before a single chip flies.
