High-speed Tungsten Carbide Internal Threading | NEUAR EDM
When machining ultra-hard tungsten carbide using traditional CNC milling, tool wear is typically very high, resulting in significant cost. However, by using EDM technology, tool wear can be drastically reduced. NEUAR's latest AEII EDM technology significantly shortens discharge time for tungsten carbide thread machining. Unlike traditional methods that require at least two electrodes to machine internal threads in tungsten carbide, the SH2 model equipped with the "Super Hard Tungsten Carbide Circuit" enables completion of internal threading with just one electrode. 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.

Machining Case Study
Auto-calculates Required Loran Radius
For M3~M20 metric threads, simply select the size. NEUAR EXPERT system automatically calculates the optimal Loran radius based on electrode wear, whether for tungsten carbide or pre-hardened steel.
Using Just Only ONE Electrode
NEUAR all CNC series equipped with "Super Hard Tungsten Carbide Circuit (SH2)" ensures the screw fits tightly by using only ONE electrode.
Machining Case Study： Tungsten Carbide M6/M10 Internal Thread Machining
With just one copper electrode, even ultra-hard tungsten carbide materials can be machined—eliminating the need for alignment using two electrodes.
The low-wear EDM technology ensures efficient processing time while maintaining a secure, wobble-free screw fit inside the threaded hole.

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.
