Why is 302 Stainless Steel a good choice for CNC Sinker EDM?
302 Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC Sinker EDM. We tune the process to the alloy so the finished 302 Stainless Steel EDM machining part meets your dimensional and functional requirements.
Can VT machining make custom 302 Stainless Steel parts to my drawing?
Yes. 302 Stainless Steel EDM machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What surface finish is achievable on 302 Stainless Steel with CNC Sinker EDM?
Surface finish on 302 Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What tolerances can you hold for CNC Sinker EDM 302 Stainless Steel?
Achievable tolerances for 302 Stainless Steel EDM machining depend on the alloy, geometry and feature size. EDM holds tolerances to around ±0.002 mm with no cutting force on the part. Exact figures are confirmed against your drawing callouts.
What is CNC Sinker EDM 302 Stainless Steel and how is it done?
CNC Sinker EDM 302 Stainless Steel refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. Applied to 302 Stainless Steel — corrosion resistant, strong and hygienic — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
