Can VT machining make custom 431 Stainless Steel parts to my drawing?
Yes. 431 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 is CNC Wire EDM 431 Stainless Steel and how is it done?
CNC Wire EDM 431 Stainless Steel refers to wire EDM cuts conductive metal with a charged wire, achieving fine detail and tight tolerance with no cutting force. Applied to 431 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.
What is the typical lead time and minimum order for CNC Wire EDM 431 Stainless Steel?
CNC Wire EDM prototypes for 431 Stainless Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Can you EDM-machine hardened 431 Stainless Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult 431 Stainless Steel can be machined to fine detail and tight tolerance without distortion.
Does CNC Wire EDM 431 Stainless Steel require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
