Core Technologies of High-Speed Mirror EDM Machines

In the EDM industry, achieving a mirror surface finish often requires adding powder to the dielectric fluid. However, NEUAR’s EDM machines utilize advanced mirror-finish discharge circuit technology that achieves an ultra-fine surface roughness of Ra 0.08 µm—without the need for any powder additives. This innovation not only enhances machining efficiency but also significantly reduces the time and cost of post-processing, delivering exceptional economic benefits to users.

No more Polishing required
NEUAR specializes in mirror surface technology. Through optimized power control and discharge parameter tuning, the new system features the second-generation “HQM2 – Hyper Quality Mirror Circuit,” which eliminates uneven reflection issues and achieves uniform and stable machining results. For mirror surface requirements in plastic molds, this technology eliminates the need for manual polishing, allowing molds to be used directly on machines.
Whether facing the challenges of intricate textures or pursuing the highest surface quality, our mirror EDM technology meets your most demanding requirements—offering a reliable and efficient solution for precision manufacturing and helping customers create highly competitive products.

Ultra Low Wear Control
The ultra-low wear control technology ensures the finishing electrodes almost no wear, keeping edges and corners sharp and distinct.

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.
