CNC Punching 309S Stainless Steel is part of VT machining's grade-specific capability. 309S Stainless Steel is corrosion resistant, strong and hygienic, and we combine controlled punching with material-aware setup to produce parts that meet your specification.
CNC Punching Capability for 309S Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 309S Stainless Steel with CNC Punching
309S Stainless Steel behaves predictably under CNC Punching 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 309S Stainless Steel run consistently from one batch to the next.
Why 309S Stainless Steel?
309S 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.
CNC Punching Tolerances & Surface Finish
Punched 309S Stainless Steel holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
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.
Secondary Operations & Finishing
Finished 309S 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.
Design Tips for CNC Punching 309S Stainless Steel
We are happy to suggest design tweaks that improve manufacturability. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched 309S Stainless Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Punching 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 309S Stainless Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Applications of CNC Punching 309S Stainless Steel
Customers order CNC Punching 309S 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 is the typical lead time and minimum order for CNC Punching 309S Stainless Steel?
CNC Punching prototypes for 309S 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.
What tolerances can you hold for CNC Punching 309S Stainless Steel?
Achievable tolerances for 309S Stainless Steel punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
What is CNC Punching 309S Stainless Steel and how is it done?
CNC Punching 309S Stainless Steel refers to cNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns. Applied to 309S 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.
What surface finish is achievable on 309S Stainless Steel with CNC Punching?
Surface finish on 309S Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
How clean are the edges produced by CNC Punching on 309S Stainless Steel?
Punched 309S Stainless Steel edges are clean when punch/die clearance is correct; we set clearance to the gauge and can add deburring if specified.
