CNC EDM Drilling 304 Stainless Steel

CNC EDM Drilling 304 Stainless Steel from VT machining delivers precision 304 Stainless Steel parts made to your exact drawing. Fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM, with parameters tuned to 304 Stainless Steel, which is corrosion resistant, strong and hygienic.

CNC EDM Drilling 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 EDM Drilling

When EDM machining 304 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 304 Stainless Steel mean predictable cycle times and stable, repeatable results.

Why 304 Stainless Steel?

Customers select 304 Stainless Steel for CNC EDM Drilling because it is corrosion resistant, strong and hygienic. We handle grade verification and any required heat treatment or finishing.

CNC EDM Drilling Tolerances & Surface Finish

EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the 304 Stainless Steel part, producing fine, controlled surface textures and sharp internal corners impossible to mill.

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.

Secondary Operations & Finishing

Most 304 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.

Design Tips for CNC EDM Drilling 304 Stainless Steel

Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened 304 Stainless Steel that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.

CNC EDM Drilling 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.

Applications of CNC EDM Drilling 304 Stainless Steel

304 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 EDM Drilling 304 Stainless Steel

Starting your project takes one email. Send your CAD or 2D drawing, the 304 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.
