Die sinking electrical discharge machine AF70(U)

precisionhigh-productivitywith electrode changer

Overview
The AF(U) Series precision CNC die‑sinker EDM machines are next‑generation units designed for high‑precision mold and component machining. The platform integrates a modern graphical operating system, upgraded electrical and mechanical architecture, and features that reduce electrode consumption while increasing machining speed and mirror‑finish capability. The machines include a remote operation center, automatic lifting work tank door and a 17″ LCD touchscreen to simplify operator interaction. The AF70(U) is suitable for moldmaking, aerospace components, special materials and automated production lines.
