Can you EDM-machine hardened 7075 Aluminum?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult 7075 Aluminum can be machined to fine detail and tight tolerance without distortion.
Why is 7075 Aluminum a good choice for CNC Wire EDM?
7075 Aluminum is lightweight with excellent machinability, which makes it well suited to CNC Wire EDM. We tune the process to the alloy so the finished 7075 Aluminum EDM machining part meets your dimensional and functional requirements.
What is CNC Wire EDM 7075 Aluminum and how is it done?
CNC Wire EDM 7075 Aluminum refers to wire EDM cuts conductive metal with a charged wire, achieving fine detail and tight tolerance with no cutting force. Applied to 7075 Aluminum — lightweight with excellent machinability — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What tolerances can you hold for CNC Wire EDM 7075 Aluminum?
Achievable tolerances for 7075 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.
What surface finish is achievable on 7075 Aluminum with CNC Wire EDM?
Surface finish on 7075 Aluminum is controlled to your specification; we confirm the achievable Ra against your callout.
Can VT machining make custom 7075 Aluminum parts to my drawing?
Yes. 7075 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.
