Tungsten carbide machining | NEUAR EDM
To address the challenge of high electrode wear during machining of ultra-hard materials, the dedicated hard alloy circuit was developed. This technology effectively reduces machining loss and ensures that even the finest sharp-angle details are clearly defined, meeting the demands of high-precision mold manufacturing. AE II core tech delivers powder-free mirror finish to Ra 0.06–0.08 µm, 5 µm corners, ±10% Ra control and 18 m/min Z-jump for deep holes. See HQM2, SPRUE & book a demo.

The new AE II discharge power system breaks past limits and streamlines programming in 5 steps. Achieve ultra-fine mirror surfaces around Ra 0.06–0.08 µm without adding powder; HQM2 expands large-area finishing, cutting post-polish time and cost.
SPRUE module targets mirror-finish angled gates with excellent stability. AE II auto-generates Z-axis linear and 3-axis paths; the C-axis refines angles for precision molds. For IC packaging molds, the large-area fine circuit keeps overall Ra within ±10% of target—ideal for high-density, tight-tolerance tooling.
Hard-alloy circuits suppress wear on ultra-hard materials; SH2’s tungsten-carbide thread circuit completes internal threads with a single electrode. High-speed gap monitoring speeds graphite electrode finishing, while EtherCAT control enables Z-axis jumping to 18 m/min for efficient deep-hole machining—request tech notes or a live demo.
