CNC Boring Stainless Steel from VT machining delivers precision Stainless Steel parts produced to your exact drawing. Boring enlarges and finishes existing holes to precise diameter, roundness and surface finish, and we tune every parameter to the behaviour of Stainless Steel, which is corrosion resistant, strong, hygienic (304/316 grades).
CNC Boring Capability for Stainless Steel
- Bore tolerance to IT6
- Roundness within 0.005 mm
- Fine boring heads
- Large-diameter capability
How CNC Boring Stainless Steel Works
The Stainless Steel 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.
Working with Stainless Steel
Stainless Steel is corrosion resistant, strong, hygienic (304/316 grades). 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.
Secondary Operations & Finishing
Most Stainless Steel 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.
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.
Design Tips for CNC Boring Stainless Steel
Small design adjustments often cut cost and lead time. Consistent diameters, standard thread forms and avoiding extremely long, slender features help Stainless Steel turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Boring Tolerances & Surface Finish
Turned Stainless Steel 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.
Applications of CNC Boring Stainless Steel
Stainless Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What is the typical lead time and minimum order for CNC Boring Stainless Steel?
CNC Boring prototypes for Stainless Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
How clean are the edges produced by CNC Boring on Stainless Steel?
Machined Stainless Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What surface finish is achievable on Stainless Steel with CNC Boring?
Surface finish on Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
Can VT machining make custom Stainless Steel parts to my drawing?
Yes. Stainless Steel Stainless Steel turning is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
