Overview
The ONA JET 15 is a compact CNC sinker EDM machine designed for precision die and mold work, toolmaking, and medical component production. Built at ONA's facility in the Basque Country of Spain, the JET 15 represents ONA's entry into high-performance sinker EDM with a focus on surface finish quality, ease of use, and energy-efficient operation.
The machine features ONA's ONAWIN control system with an intuitive touchscreen interface that simplifies electrode programming, erosion parameter selection, and orbital motion strategies. The generator employs adaptive pulse control technology that monitors gap conditions in real time and adjusts pulse parameters to maximize material removal rate while protecting electrode geometry and achieving target surface finishes.
With a work tank capacity suited to medium-sized mold inserts and die components, the JET 15 handles graphite and copper electrodes across a broad range of workpiece materials including hardened tool steels, carbide, and aerospace alloys. Its dielectric filtration system maintains fluid cleanliness essential for fine-finish erosion cycles, and the machine's thermal stability design minimizes the effect of ambient temperature variation on part accuracy.
The JET 15 targets job shops, moldmakers, and precision toolrooms looking for a reliable, operator-friendly sinker EDM without the complexity of larger production-oriented machines. ONA's European service network provides local support, and the machine's modular design allows field upgrades to its generator and control system as technology advances.

Frequently Asked Questions
01
The JET 15 works with graphite and copper electrodes, with optimized generator settings for each material. Graphite is preferred for high-speed roughing while copper is used for fine finishing and tight-tolerance applications.
02
Yes. With fine-finish erosion cycles and mirror EDM parameters, the JET 15 can achieve surface finishes of Ra 0.1 µm or better, suitable for optical mold inserts and high-polish die cavities.
03
Yes. The ONAWIN control supports orbital erosion strategies (circular, square, planetary) that improve corner accuracy, reduce electrode wear, and help achieve uniform surface finish across complex cavity geometries.
