CNC Drilling 304L Stainless Steel

CNC Drilling 304L Stainless Steel is part of VT machining's grade-specific capability. 304L Stainless Steel is corrosion resistant, strong and hygienic, and we combine controlled machining with material-aware setup to produce parts that meet your specification.

CNC Drilling Capability for 304L Stainless Steel

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

Machining 304L Stainless Steel with CNC Drilling

304L Stainless Steel behaves predictably under CNC Drilling 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 304L Stainless Steel run consistently from one batch to the next.

Why 304L Stainless Steel?

304L 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 Drilling Tolerances & Surface Finish

For CNC Drilling, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.

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 Drilling 304L Stainless Steel

We are happy to suggest design tweaks that improve manufacturability. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in 304L Stainless Steel. If you send your model early, we will return practical DFM feedback before you commit to production.

CNC Drilling 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 304L Stainless Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.

Secondary Operations & Finishing

Finished 304L 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.

Applications of CNC Drilling 304L Stainless Steel

Customers order CNC Drilling 304L 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.

How to Order CNC Drilling 304L Stainless Steel

Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.
