VT machining specialises in CNC Boring S355JR Steel. Because S355JR Steel is strong, economical and widely available, and its machinability is good to excellent depending on carbon content; free-machining grades cut cleanly, we plan each job around the grade to protect accuracy and surface quality.
CNC Boring Capability for S355JR Steel
- Carbon/low-alloy grades
- Economical & weldable
- Tolerance to ±0.02 mm
- Hardenable by heat treat
Machining S355JR Steel with CNC Boring
The machinability of S355JR Steel is good to excellent depending on carbon content; free-machining grades cut cleanly. For CNC Boring we select tooling, feeds, speeds and coolant to match, keeping the S355JR Steel workpiece stable and the result accurate.
Because we machine S355JR Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
CNC Boring Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on S355JR Steel parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Secondary Operations & Finishing
We complete S355JR Steel components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Design Tips for CNC Boring S355JR Steel
A few design choices make a real difference to cost and quality. 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?
Specifying S355JR Steel for CNC Boring S355JR Steel is usually about its properties: strong, economical and widely available. Tell us the condition you need and we machine to it.
CNC Boring 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.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Applications of CNC Boring S355JR Steel
