CNC Turning
Round and cylindrical parts turned to your drawing. Shafts, pins, bushings, fittings, flanges, collars and threaded parts, with secondary milling for combined features, inspected in-house, AS9100D certified.
Quote in 48h
Prototypes 10–15 business days
Production 15–30 business days
No minimum order
CNC turning is core to what Fenva does. Bar and chuck work covers the round-part families that every assembly needs, and our live-tooling lathes finish turned-plus-milled features in one setup, so parts come off complete instead of moving between machines. Send a drawing and you get a line-item quote in 48 hours, one prototype or a production batch, with no minimum order.
Capability
Turning we run
| Capability | What it is | Why you pick it | Parts |
|---|---|---|---|
| Bar / chuck turning | Standard 2-axis lathe work from bar stock or chucked blanks | Economical, fast, the workhorse for round parts | Shafts, pins, bushings, spacers, collars |
| Live-tooling mill-turn | Turning plus driven milling, drilling and tapping in one setup | Fewer setups, tighter feature-to-feature accuracy | Fittings, manifolds, valve bodies, shafts with flats |
| Swiss turning | Sliding-headstock work via an on-site part-owned affiliate | Best for small, slender, high-precision turned parts | Small pins, contacts, connector parts, micro shafts |
| Threading | Single-point, tapped and rolled threads | Clean, repeatable threads to your callout | Studs, fittings, adjusters, threaded shafts |
| Flanges / discs | Large-diameter chuck work with faces and bores | Flat, true faces and concentric bores | Flanges, end caps, retaining rings, plates |
Machine envelope
What we can turn, and how big
Across our CNC turning centres and Swiss machines. Achievable results depend on geometry and material, confirmed at DFM review.
| Parameter | Capacity |
|---|---|
| Max part diameter | 500 mm |
| Max part length | 580 mm |
| Max swing over carriage | 500 mm |
| Max spindle through-hole | Φ62 mm |
| Parameter | Capacity |
|---|---|
| Max bar capacity | Ø32 / Ø42 mm |
| Max turning diameter | Ø125 mm |
| Max turning length | 320 mm |
| Guide bushing | Yes |
Larger or longer parts may be possible, ask our engineering team at DFM review.
Tolerances
What we can hold
- Bar and chuck turning plus live-tooling mill-turn, so turned-plus-milled parts finish in fewer setups.
- 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.
- Tight concentricity, fine threads and slender shafts, with DFM feedback before machining begins.
Where it goes
Hydraulics and fittings, electronics and connectors, components for medical and lab equipment, automotive, robotics and automation, and commercial aerospace and UAV.

Why Fenva
Why Fenva for turning
Triple-certified
AS9100D, ISO 9001 and IATF 16949, not just ISO 9001.
Prototype to production
No minimum order. The same drawing and the same inspection from one piece to a full batch.
We take full responsibility for what we machine
We machine strictly to your drawing and take full responsibility for the result.
Mini-FAQ
CNC turning, answered
Do you offer Swiss turning?
Yes, via an on-site part-owned affiliate, best for small high-precision turned parts. Our in-house core is milling and turning.
Max diameter and length?
Send the drawing and we confirm fit fast. We run a wide envelope of bar and chuck sizes across about 97 machines.
Can you do mill-turn?
Yes. Live tooling adds milling, drilling and tapping to turned parts in one setup.
Lead time?
Prototypes about 10 to 15 business days, production about 15 to 30, quote in 48 hours.
