CNC subcontract machining · South Wales
Precision parts from your drawing, made by the person who quotes them.
Delta1 is a CNC shop doing Swiss-type turning, CNC turning and milling. Prototypes and small batches are our focus, with the capacity for larger production runs when you need them.
Small, accurate parts. Done properly.
Swiss-type and CNC turning
Sliding-head turning for small, slender, detailed parts, from prototypes to larger production runs, plus fixed-head CNC turning for bigger diameters and chucked work.
CNC milling
Brackets, plates, housings, fixtures and soft jaws. Prismatic parts and second operations on turned work, in metals and engineering plastics.
Inspection and finishing
Deburring, cleaning and checking against your drawing before anything leaves. Inspection reports and material certs when your job needs them.
From drawing to delivered in four steps.
Send your drawing
A STEP file and a PDF drawing is ideal. A sketch with the key dimensions is fine to start a conversation.

Price, lead time and any notes on features that are driving cost, so you can decide with the full picture.
We make it
Programmed, set up and run in-house, with first-off checks before the batch carries on.
Inspected and shipped
Checked against the drawing, cleaned, packed and sent, with paperwork if you need it.
In engineering, Δ means change.
We want to be the one change that makes the difference to your product: the part that turns up right, on time, the first time.
Talk to the machinist
The person who quotes your job is the person who programs and runs it. No account managers, no lost messages.
Honest feedback
If a tolerance or feature is adding cost without adding function, we will tell you before we cut metal.
Built for small runs, ready for big ones
Prototypes and small batches are what we are set up for, not a nuisance between big jobs. When your product takes off, the Swiss handles the bigger runs.
Quality from day one
Measured, recorded and traceable, with our quality system being built around ISO 9001.
