Sinker EDM

for Aerospace Tooling & Complex Geometry

Creating Intricacy & Detail with Tight Tolerances

Burke Aerospace provides high-precision sinker EDM services for aerospace and defense components requiring intricate internal geometries, sharp corner detail, and tight tolerance control.

Sinker EDM (also known as ram EDM) uses shaped electrodes to erode material and form complex cavities and features that are difficult or impossible to produce using conventional machining. This process is ideal for hardened materials and high-precision tooling applications.
