Precision milling
3-axis milling and indexed 4th-axis work for tight-tolerance components, from first article through repeat production.
Standard
±0.001 in · ±0.0002 in on critical features
Capabilities
Small details.
Big consequences.
Instrument housings, fixtures, and fitted hardware in aluminum, copper, and plastics. One-offs through runs of a few thousand.
Tighter than ±0.0005", talk to us first — we'll tell you honestly whether it's a fit and what inspection it needs.
No CMM in-house.
Turning — partner shop
Turned parts are produced through a vetted partner shop under our inspection and our PO. You get one point of contact, one quote, and the same inspection standard.

First article & short runs
Prototype parts, first articles, fixtures, and repeat mill work with the same team handling programming, machining, and inspection.
Run type
One-offs · repeat work
Typical lead time
2–3 days
Full inspection
Every part is inspected against the print before it ships. Micrometers, calipers, gage pins, and a height gage on a granite surface plate — all on a documented calibration schedule. Certs of conformance and first-article reports on request.

Work envelope
up to 30" × 16" × 20" on the VF-2SS; the Mini Mill runs small parts and second ops in parallel, so a rush job doesn't queue behind a production run.
Materials
aluminum, copper, brass, plastics
CAD/CAM
Fusion 360 · files accepted: STEP, IGES, DXF, PDF
Lead time
2–3 days typical on prototype and short-run work
Our working rhythm
No black
boxes.
You’ll always know what’s happening, what’s next, and whether we’re on track. That’s part of the work.
01
Scope
Send a model, a sketch, or a problem. We’ll ask the useful questions and get specific.
02
Make
Your parts move through programming, machining and inspection with one team accountable.
03
Deliver
Packed carefully, documented clearly, and at the time we committed to.
Selected work
The proof
is in the part.

A shop with a memory
We remember the
last 0.001".
Helios started with one mill and a simple idea: if we say a part will be right, it should be right. Five years later, that still guides how we quote, schedule, inspect and communicate — whether you need a production run, a prototype, or a single custom part.
Quality. We run a documented quality system modeled on ISO 9001 — traveler per job, documented inspection, calibration schedule, and nonconformance handling. We are not ISO certified. We are built to be audited, and we'll walk you through the system before you place an order.
