CNC Turning Capability
CNC Turning
CNC turning of cylindrical and complex components to ±0.005 mm, CMM-verified for repeatable accuracy and superior finishes.
MILL-TURN ±0.005 mm
CNC Turning
In
brief
Milltech's CNC turning produces cylindrical and complex components to tolerances as tight as ±0.005 mm where required, CMM-verified in Norwich, UK. Multi-axis mill-turn and sub-spindle machines from Biglia, Doosan, Mazak and Star complete intricate parts in fewer operations — across aluminium, brass, stainless, steel, exotics and plastics, from prototype to repeatable volume.
C-02 · CNC Turning Overview
CNC turning produces precise cylindrical parts by removing material from a rotating workpiece. Our turning cell pairs a broad machine list with CMM verification to deliver complex geometries, fine finishes and repeatable accuracy at any volume.
Tight tolerances
Our turning centres achieve tolerances as tight as ±0.005 mm where the application demands it.
Mill-turn & sub-spindle
Multi-axis mill-turn and sub-spindle machines complete complex parts in fewer operations.
Material breadth
From aluminium and brass to stainless, exotics and plastics — matched to the job.

Insights
CNC Turning — the detail
Capability & tolerancesWhat is the difference between CNC milling and CNC turning?
CNC milling vs CNC turning explained — how each process works, what parts each suits, and when you need mill-turn to do both in one operation.
Capability & tolerancesWhat is mill-turn machining?
What mill-turn and sub-spindle machining is, how it completes complex parts in fewer operations, and why it improves accuracy and lead time.
Capability & tolerancesWhat is precision CNC machining?
What precision CNC machining is, how CNC control delivers tight tolerances and repeatability, and what makes machining precision rather than general.
FAQ
CNC Turning — your questions
What tolerances can your CNC turning achieve?
As tight as ±0.005 mm where the application demands it, CMM-verified for repeatable accuracy.
