CNC Polishing 347 Stainless Steel is part of VT machining's grade-specific capability. 347 Stainless Steel is corrosion resistant, strong and hygienic, and we combine controlled finishing with material-aware setup to produce parts that meet your specification.
CNC Polishing Capability for 347 Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 347 Stainless Steel with CNC Polishing
When finishing 347 Stainless Steel, machinability is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for 347 Stainless Steel mean predictable cycle times and stable, repeatable results.
Why 347 Stainless Steel?
Customers select 347 Stainless Steel for CNC Polishing because it is corrosion resistant, strong and hygienic. We handle grade verification and any required heat treatment or finishing.
Secondary Operations & Finishing
Most 347 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 Polishing Tolerances & Surface Finish
Finishing brings 347 Stainless Steel to a defined roughness target — from a uniform satin to Ra values as low as 0.05 µm — with controlled, repeatable edge breaks.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
CNC Polishing 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 Polishing 347 Stainless Steel
Small design adjustments often cut cost and lead time. Telling us the target Ra, the cosmetic faces and any masking needs lets us finish 347 Stainless Steel efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Polishing 347 Stainless Steel
347 Stainless Steel 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 Polishing 347 Stainless Steel
Starting your project takes one email. Send your CAD or 2D drawing, the 347 Stainless Steel grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.

How clean are the edges produced by CNC Polishing on 347 Stainless Steel?
Our deburring leaves 347 Stainless Steel with a consistent, controlled edge break and burr-free surfaces.
What surface finish is achievable on 347 Stainless Steel with CNC Polishing?
Our finishing processes refine 347 Stainless Steel surfaces to Ra values as low as 0.05 µm for cosmetic or sealing faces.
Does CNC Polishing 347 Stainless Steel require dedicated tooling?
Most 347 Stainless Steel finishing work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is 347 Stainless Steel a good choice for CNC Polishing?
347 Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC Polishing. We tune the process to the alloy so the finished 347 Stainless Steel finishing part meets your dimensional and functional requirements.
