CNC Precision Machining S355JR Steel

CNC Precision Machining S355JR Steel is part of VT machining's grade-specific capability. S355JR Steel is strong, economical and widely available, and we combine controlled machining with material-aware setup to produce parts that meet your specification.

CNC Precision Machining Capability for S355JR Steel

• Carbon/low-alloy grades
• Economical & weldable
• Tolerance to ±0.02 mm
• Hardenable by heat treat

Machining S355JR Steel with CNC Precision Machining

S355JR Steel behaves predictably under CNC Precision Machining once parameters are dialled in: machinability is good to excellent depending on carbon content; free-machining grades cut cleanly, and we tune the operation accordingly.

We hold reference parameters for this grade, so repeat orders of S355JR Steel run consistently from one batch to the next.

Secondary Operations & Finishing

Finished S355JR 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 Precision Machining S355JR 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 S355JR Steel. If you send your model early, we will return practical DFM feedback before you commit to production.

CNC Precision Machining 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 S355JR Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.

CNC Precision Machining Tolerances & Surface Finish

For CNC Precision Machining, 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.

Why S355JR Steel?

S355JR Steel is chosen when a part needs what this grade offers — it is strong, economical and widely available. We confirm the grade and any temper or heat-treat condition with you before machining.

Applications of CNC Precision Machining S355JR Steel

Customers order CNC Precision Machining S355JR 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.
