Super Shining mirror surface in Ra 0.06μm

Core Technologies of Automated High-Speed EDM Machines

In the industry, it is common to add powder to the machining fluid during EDM mirror surface processing to achieve a large-area mirror effect. However, NEUAR's EDM machine, with its advanced mirror EDM circuit technology, achieves ultra-fine mirror effects with a surface roughness of Ra 0.06 µm over large areas, without the need to add powder to the machining fluid. The built-in High Quality Mirror Circuit (HQM2) expands the machinable surface area for finer finishing. eliminating post-polishing process, enables immediate use after machining.


Machining Case Study

Through optimized power control and discharge parameter adjustments, NEUAR ensures consistent surface machining quality even for large workpieces, preventing uneven reflection and achieving uniform and stable results. This technology is particularly well-suited for applications requiring extremely high surface finish, such as high-end mold manufacturing, optical component processing, and semiconductor packaging.
Whether addressing the challenge of fine textures or striving for exceptional surface quality, our mirror finish technology meets your high demands, providing reliable and efficient solutions for precision manufacturing and helping customers create highly competitive products.

Super Shining mirror surface in Ra 0.06μm | NEUAR EDM

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.
