CNC Polishing 904L Stainless Steel

VT machining specialises in CNC Polishing 904L Stainless Steel. Because 904L Stainless Steel is corrosion resistant, strong and hygienic, and its machinability is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, we plan each job around the grade to protect accuracy and surface quality.

CNC Polishing Capability for 904L Stainless Steel

• Austenitic/martensitic grades
• Corrosion resistant
• Tolerance to ±0.01 mm
• Typical hardness 70–200 HB (annealed)

Machining 904L Stainless Steel with CNC Polishing

When finishing 904L 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 904L Stainless Steel mean predictable cycle times and stable, repeatable results.

CNC Polishing Tolerances & Surface Finish

Finishing brings 904L 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.

Design Tips for CNC Polishing 904L 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 904L Stainless Steel efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.

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.

Secondary Operations & Finishing

Most 904L 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.

Why 904L Stainless Steel?

Customers select 904L Stainless Steel for CNC Polishing because it is corrosion resistant, strong and hygienic. We handle grade verification and any required heat treatment or finishing.
