High accuracy - ±0.015mm cutting precision, ±0.01mm/300mm straightness, and 0.001mm single-pulse accuracy thanks to P3-grade ball screws and 5-phase stepper motors.
Fast cutting - 100 mm²/min max speed, works on any conductive material (steel, carbide, magnetic alloys, thin walls).
Taper & capacity - 300*360mm table, 400mm workpiece height, standard ±3° taper (optional up to ±45°).
Low operating cost - Consumes only 1.2 KVA, cuts energy bills by ~30% vs. conventional EDM.
Good finish - Ra 1.6-2.5 μm, 4-axis linkage for smoother contours, supports multi‑cut (CoolCut) for even better finish.
Easy maintenance - Automatic wire tensioning, 320m wire storage, fast return‑to‑zero (50k steps/sec) to reduce downtime.

Frequently Asked Questions

What factors should I consider when selecting the right machine?

When choosing a machine, first match the worktable travel and cutting capacity to the size and thickness of your workpiece to identify a suitable model. Additionally, verify whether the precision and surface finish meet your standards.

The standard voltage in our country is three-phase 220V (or single-phase 220V, etc.), but your machine uses three-phase 380V. Is voltage adjustment possible?

Absolutely. Just let us know your specific voltage requirements, and we can customize the machine accordingly.

What details do you need from us to prepare a proposal?

We'll need the worktable dimensions, required travel range, and any special requirements you may have.

Are you a manufacturer or a trading company?

We specialize in manufacturing CNC machine tools and have over 20 years of experience in this industry.
