VT machining specialises in CNC Sinker EDM 303 Stainless Steel. Because 303 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 Sinker EDM Capability for 303 Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 303 Stainless Steel with CNC Sinker EDM
The machinability of 303 Stainless Steel is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing. For CNC Sinker EDM we select tooling, feeds, speeds and coolant to match, keeping the 303 Stainless Steel workpiece stable and the result accurate.
Because we machine 303 Stainless Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
CNC Sinker EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the 303 Stainless Steel part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
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 Sinker EDM 303 Stainless Steel
A few design choices make a real difference to cost and quality. EDM suits sharp internal corners, thin ribs and hardened 303 Stainless Steel that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Sinker EDM Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on 303 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.
