CNC Boring Aluminum is a core capability at VT machining. We combine controlled turning with material-aware setup for Aluminum — an alloy that is lightweight, excellent machinability, good corrosion resistance — to produce parts that meet your specification first time.
CNC Boring Capability for Aluminum
- Bore tolerance to IT6
- Roundness within 0.005 mm
- Fine boring heads
- Large-diameter capability
How CNC Boring Aluminum Works
The Aluminum bar or billet rotates in the spindle while single-point tools shape outer diameters, bores, faces, grooves and threads. Constant surface speed control keeps cutting conditions stable from large to small diameters.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
CNC Boring Tolerances & Surface Finish
Turned Aluminum holds diameter tolerances to about ±0.005 mm with concentricity within 0.01 mm and good roundness. Turned finishes of Ra 0.4–0.8 µm are achievable with finishing passes and sharp tooling.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
CNC Boring Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Secondary Operations & Finishing
Most Aluminum parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Design Tips for CNC Boring Aluminum
Small design adjustments often cut cost and lead time. Consistent diameters, standard thread forms and avoiding extremely long, slender features help Aluminum turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
Working with Aluminum
Aluminum is lightweight, excellent machinability, good corrosion resistance. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.
Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.
Applications of CNC Boring Aluminum
Aluminum parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order CNC Boring Aluminum

What tolerances can you hold for CNC Boring Aluminum?
Achievable tolerances for Aluminum turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
What is the typical lead time and minimum order for CNC Boring Aluminum?
CNC Boring prototypes for Aluminum can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What is CNC Boring Aluminum and how is it done?
CNC Boring Aluminum refers to boring enlarges and finishes existing holes to precise diameter, roundness and surface finish. Applied to Aluminum — lightweight, excellent machinability, good corrosion resistance — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What material thickness or size range suits CNC Boring Aluminum?
Turned Aluminum parts are produced from bar or chuck stock across a wide diameter range.
