Overview

The ONA NX 6 is a mid-range wire EDM machine from Spanish precision machine tool manufacturer ONA Electroerosion, designed for precision toolroom and production cutting applications in industrial Europe and globally. The NX 6 features ONA's NControl touch interface and their latest ONAgen digital power generator, providing high-speed cutting with fine surface finish capability. The 600x400mm work table (XY travel) handles medium-format die inserts, extrusion tooling, and aerospace brackets. The cutting height of 320mm accommodates stacked or tall workpieces. ONA's intelligent auto wire threading system handles threading through start holes in submerged conditions, enabling unattended night-shift production. The NX 6 is ONA's primary offering to the extrusion die, stamping tool, and injection mold sectors across European and Latin American markets.

Strengths & Limitations

Strengths

600x400mm table — larger than many competitors at this price
Submerged auto wire threading for unattended production
ONAgen digital generator for clean surface finish
Spanish ONA has strong service presence in Europe and Latin America
NControl touchscreen for intuitive operation

Limitations

ONA less established in North America vs GF, Mitsubishi, or Sodick
250 mm²/min cutting speed lower than top-tier GF or Sodick systems
0.15 µm Ra (good but not best-in-class)

Best For

European extrusion die shops, stamping tool makers, and injection mold manufacturers seeking a capable mid-range wire EDM with large work area and competitive cost.
