Materials we run
Aluminium 6061, 7075, 7050 and 6082; stainless and tool steels; brass and copper; engineering plastics. Aluminium is our deepest strength and highly economical to mill at volume.

3-Axis CNC Machining
3-axis milling is the fast, economical way to make prismatic parts. Plates, brackets, housings, covers and fixtures, cut to your drawing, inspected in-house, AS9100D certified.
Quote in 48h
Prototypes 10–15 business days
Production 15–30 business days
No minimum order
Most machined parts do not need five axes. If your part is built from flat faces, pockets, bores and holes that a tool can reach from the top, 3-axis milling is faster to set up, faster to cut and cheaper per piece. Fenva runs a large 3-axis fleet, so we hold price down on prototypes and keep capacity open for volume. Send a drawing and you get a line-item quote in 48 hours, one piece or a production batch, with no minimum order.
Fit
When 3-axis is the right choice
| Part type | Why 3-axis fits | What it saves you |
|---|---|---|
| Plates and bases | All features reach from one or two faces | Lower cost, quick turnaround |
| Brackets and mounts | Prismatic geometry, simple workholding | Cheaper than 5-axis for the same result |
| Housings and covers | Open pockets and bores, flat datums | High throughput on volume runs |
| Fixtures and tooling | Functional, in-house quick turn | Quick setup, low piece price |
| Manifolds and blocks | Drilled and tapped from accessible faces | Repeatable across large lots |
Tolerances
What we can hold
- 3-axis milling with quick, repeatable setups, so volume runs stay cheap and on time.
- General tolerance ISO 2768-m as standard; down to ±0.01 mm on the features that need it.
- Surface finish to about Ra 1.6 off the machine, finer on request.
- Deep pockets, tight bores and thin walls, with DFM feedback before machining begins.
Finishes
As-machined, bead blast, brushed, anodizing (Type II and Type III), black oxide, passivation, and chromate conversion.

Mini-FAQ
3-axis machining, answered
3-axis or 5-axis, which is cheaper?
3-axis, when the part allows it. If every feature reaches from the top in one or two setups, 3-axis is the lower-cost choice. We move you to 5-axis only when the geometry needs it.
Can you handle volume?
Yes. A large 3-axis fleet keeps capacity open for production runs at a steady piece price.
Tightest tolerance?
Down to ±0.01 mm on critical features, with general dimensions to ISO 2768-m.
Lead time?
Prototypes about 10 to 15 business days, production about 15 to 30, quote in 48 hours.
