VT machining provides CNC Swiss Machining S355JR Steel for customers who need accurate, repeatable S355JR Steel components. The machinability of S355JR Steel is good to excellent depending on carbon content; free-machining grades cut cleanly, so we set the operation up specifically for this grade.
CNC Swiss 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 Swiss Machining
When turning S355JR Steel, machinability is good to excellent depending on carbon content; free-machining grades cut cleanly. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for S355JR Steel mean predictable cycle times and stable, repeatable results.
CNC Swiss Machining Tolerances & Surface Finish
Turned S355JR Steel holds diameter tolerances to about ±0.005 mm with concentricity within 0.01 mm and good roundness. Turned finishes of Ra 0.4–0.8 µm are achievable with finishing passes and sharp tooling.
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 Swiss Machining 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 Swiss Machining S355JR Steel
Small design adjustments often cut cost and lead time. Consistent diameters, standard thread forms and avoiding extremely long, slender features help S355JR Steel turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
Why S355JR Steel?
Customers select S355JR Steel for CNC Swiss Machining because it is strong, economical and widely available. We handle grade verification and any required heat treatment or finishing.
Secondary Operations & Finishing
Most S355JR 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.
Applications of CNC Swiss Machining S355JR Steel
S355JR Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
