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. We turn 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, chosen to suit the job.

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.
Do you offer mill-turn and sub-spindle turning?
Yes. Multi-axis mill-turn and sub-spindle machines complete complex turned parts in fewer operations, for finer finishes and tighter feature control.
What materials can you turn?
Aluminium, brass, stainless steel, steel, copper, exotics and plastics, each matched to the application.
Which turning machines do you run?
Biglia, Doosan, Mazak, Star, HAAS, Colchester and DMG turning centres, including mill-turn and sub-spindle machines for complex parts.
How fast can I get a turning quote?
