Wire electro discharge machining (WEDM) uses electric current and fine wire to cut conductive materials with low residual stress to exceptionally tight tolerances.
Why use WEDM?
WEDM offers tolerances to ±0.005mm. The process is burr-free, distortion-free and can be used to machine exotic materials which are work-hardened, ductile or brittle.
As the axis of the wire can be rotated to produced tapered-cuts, free-curves and complex geometries with exceptionally straight profiles, allowing components to be stacked for low-mid volume production.
Precision Micro and WEDM
Precision Micro is one of the few etching companies to offer WEDM in-house. Combining WEDM with photo etching means component profiles can be cut to tighter tolerances and unique characteristics such as tapered edges can be achieved. WEDM enables the profiling of thicker, surface etched components to 3mm thick.
