VT machining specialises in CNC Thread Grinding 420 Stainless Steel. Because 420 Stainless Steel is corrosion resistant, strong and hygienic, and its machinability is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, we plan each job around the grade to protect accuracy and surface quality.
CNC Thread Grinding Capability for 420 Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 420 Stainless Steel with CNC Thread Grinding
The machinability of 420 Stainless Steel is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing. For CNC Thread Grinding we select tooling, feeds, speeds and coolant to match, keeping the 420 Stainless Steel workpiece stable and the result accurate.
Because we machine 420 Stainless Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
CNC Thread Grinding Tolerances & Surface Finish
Ground 420 Stainless Steel reaches single-micron tolerances on size, flatness and parallelism, with surface finishes down to Ra 0.1–0.4 µm — and a near-mirror finish on suitable alloys.
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.
Design Tips for CNC Thread Grinding 420 Stainless Steel
A few design choices make a real difference to cost and quality. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on 420 Stainless Steel efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Thread Grinding Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on 420 Stainless 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.
