Can VT machining make custom 6061 Aluminum parts to my drawing?
Yes. 6061 Aluminum 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.
Can you EDM-machine hardened 6061 Aluminum?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult 6061 Aluminum can be machined to fine detail and tight tolerance without distortion.
What tolerances can you hold for CNC Sinker EDM 6061 Aluminum?
Achievable tolerances for 6061 Aluminum 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.
Why is 6061 Aluminum a good choice for CNC Sinker EDM?
6061 Aluminum is lightweight with excellent machinability, which makes it well suited to CNC Sinker EDM. We tune the process to the alloy so the finished 6061 Aluminum EDM machining part meets your dimensional and functional requirements.
