CNC Boring 304 Stainless Steel is part of VT machining's grade-specific capability. 304 Stainless Steel is corrosion resistant, strong and hygienic, and we combine controlled turning with material-aware setup to produce parts that meet your specification.
CNC Boring Capability for 304 Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 304 Stainless Steel with CNC Boring
304 Stainless Steel behaves predictably under CNC Boring once parameters are dialled in: machinability is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of 304 Stainless Steel run consistently from one batch to the next.
CNC Boring Tolerances & Surface Finish
Turned 304 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.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Design Tips for CNC Boring 304 Stainless Steel
We are happy to suggest design tweaks that improve manufacturability. Consistent diameters, standard thread forms and avoiding extremely long, slender features help 304 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.
Secondary Operations & Finishing
Finished 304 Stainless Steel parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
CNC Boring Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every 304 Stainless Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Why 304 Stainless Steel?
304 Stainless Steel is chosen when a part needs what this grade offers — it is corrosion resistant, strong and hygienic. We confirm the grade and any temper or heat-treat condition with you before machining.
Applications of CNC Boring 304 Stainless Steel
Customers order CNC Boring 304 Stainless Steel components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

What surface finish is achievable on 304 Stainless Steel with CNC Boring?
Surface finish on 304 Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What is CNC Boring 304 Stainless Steel and how is it done?
CNC Boring 304 Stainless Steel refers to boring enlarges and finishes existing holes to precise diameter, roundness and surface finish. Applied to 304 Stainless Steel — corrosion resistant, strong and hygienic — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
How clean are the edges produced by CNC Boring on 304 Stainless Steel?
Machined 304 Stainless Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Why is 304 Stainless Steel a good choice for CNC Boring?
304 Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC Boring. We tune the process to the alloy so the finished 304 Stainless Steel turning part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Boring 304 Stainless Steel?
Achievable tolerances for 304 Stainless Steel 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.
