CNC Sinker EDM D3 Tool Steel from VT machining delivers precision D3 Tool Steel parts made to your exact drawing. Sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features, with parameters tuned to D3 Tool Steel, which is wear-resistant and hardenable for tooling.
CNC Sinker EDM Capability for D3 Tool Steel
- Air/oil/water-hardening grades
- High wear resistance
- Hardenable to 58–64 HRC
- Tolerance to ±0.005 mm
Machining D3 Tool Steel with CNC Sinker EDM
The machinability of D3 Tool Steel is machined in the annealed state, then hardened; carbide tooling preferred. For CNC Sinker EDM we select tooling, feeds, speeds and coolant to match, keeping the D3 Tool Steel workpiece stable and the result accurate.
Because we machine D3 Tool Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
Design Tips for CNC Sinker EDM D3 Tool Steel
A few design choices make a real difference to cost and quality. EDM suits sharp internal corners, thin ribs and hardened D3 Tool 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 Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the D3 Tool 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.
Secondary Operations & Finishing
We complete D3 Tool 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.
CNC Sinker EDM Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on D3 Tool 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.
