CNC & secondary machining

Secondary machining of extruded profiles to your production drawing — so parts arrive ready to fit, not just as mill lengths.

After extrusion, we machine profiles to your drawing: cutting, drilling, tapping, milling and assembly are done in-house. That removes the handoff to a separate machine shop and keeps one point of accountability from the profile to the finished part.

What we offer

01

Machining operations

Precision cutting, drilling, tapping, milling and slotting to your production drawing.

02

Assembly & sub-assemblies

Multi-part assemblies built up and delivered ready to fit.

03

Prototype to series

First-article samples through to repeat production runs, with the same process control.

04

Base material

Typically 6061, 6063 or 6082; other alloys on request depending on strength and machinability.

Frequently asked questions

When do I actually need secondary machining?

Whenever the extruded profile needs holes, threads, cut-outs, precise end cuts or assembly before it can be used. If your part is a plain cut length, you may not need it — send the drawing and we tell you what is required.

Can you extrude the profile and machine it in one place?

Yes. Extrusion, machining and finishing are all in-house, so a single supplier covers the profile, the machined features and the finish. That removes handoffs between separate shops and keeps one accountable contact.

Do you handle prototypes and low volumes?

Yes — first-article samples through to repeat series. Prototype quantities are fine for validating the part before a production commitment.

What tolerances can you hold?

It depends on the feature and material. Send the drawing with the critical dimensions marked and we confirm what is achievable against your ±tolerance rather than quoting a generic figure.
