CNC Boring S235JR Steel is part of VT machining's grade-specific capability. S235JR Steel is strong, economical and widely available, and we combine controlled turning with material-aware setup to produce parts that meet your specification.
CNC Boring Capability for S235JR Steel
- Carbon/low-alloy grades
- Economical & weldable
- Tolerance to ±0.02 mm
- Hardenable by heat treat
Machining S235JR Steel with CNC Boring
When turning S235JR 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 S235JR Steel mean predictable cycle times and stable, repeatable results.
Secondary Operations & Finishing
Most S235JR 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.
CNC Boring 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.
CNC Boring Tolerances & Surface Finish
Turned S235JR 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.
Design Tips for CNC Boring S235JR Steel
Small design adjustments often cut cost and lead time. Consistent diameters, standard thread forms and avoiding extremely long, slender features help S235JR Steel turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
