Overview
The ONA NX 10 is an advanced CNC sinker EDM machine from ONA Electroerosion's NX platform, engineered for high-precision die and mold applications where surface finish quality, dimensional accuracy, and process automation are critical production requirements. The NX 10 represents ONA's top-tier sinker EDM technology, incorporating the company's most capable generator system, enhanced thermal stability architecture, and automation-ready design to serve aerospace, medical device, and high-precision mold manufacturing industries.
At the core of the NX 10 is ONA's advanced digital generator with an expanded current range and refined pulse control algorithms that enable aggressive roughing alongside ultra-fine finishing within the same machine cycle. The generator's intelligent gap monitoring system operates at nanosecond response speeds, distinguishing stable spark discharges from arcs and short circuits and adjusting pulse conditions to eliminate damaging discharges before they degrade surface integrity. This level of generator sophistication is particularly valuable in deep-cavity erosion where gap conditions are difficult to control through flushing alone, and in fine-finish sequences where maintaining consistent discharge energy directly determines the achievable Ra value.
The NX 10's structural architecture prioritizes thermal stability and mechanical rigidity above all else. The machine base uses high-grade cast iron with integrated internal ribbing that maximizes stiffness while minimizing thermal mass. Temperature-controlled dielectric circulation and ambient temperature compensation in the CNC system reduce thermal positioning errors during extended production runs, enabling the NX 10 to achieve and maintain positional accuracy of ±0.001 mm across multi-hour burn cycles. This level of accuracy supports aerospace tolerance requirements and the production of high-precision gauge tooling.
Automation integration is a design priority on the NX 10. The machine's automatic electrode changer accepts up to 32 electrode positions and integrates with ONA's electrode management software for sequenced unattended operation. Pallet changing interfaces and standardized tooling systems (Erowa, System 3R) allow the NX 10 to be integrated into automated cell architectures where workpiece setup and electrode management are handled robotically. For high-volume precision component manufacturers, this capability transforms the NX 10 from a standalone machine into a fully automated erosion cell.
The ONA-CNC control on the NX 10 provides comprehensive process management including graphical electrode orbit programming, multi-electrode cycle sequencing, and remote monitoring integration. ONA's NX platform supports Industry 4.0 connectivity through standard OPC-UA and MTConnect interfaces, enabling process data collection, remote diagnostics, and integration with plant-level MES and ERP systems. For precision manufacturers operating in regulated environments such as aerospace and medical device, the NX 10's data logging and traceability features support quality system requirements.

Frequently Asked Questions
01
The NX 10 achieves positional accuracy of ±0.001 mm across extended burn cycles, supported by temperature-controlled dielectric circulation, high-resolution servo encoders, and ambient temperature compensation in the CNC. This level of accuracy is suitable for aerospace component tolerances and precision gauge tooling.
02
The NX 10's automatic electrode changer (AEC) accommodates up to 32 electrode positions, allowing multi-electrode roughing-to-finishing cycles to run unattended. ONA's electrode management software sequences operations, tracks electrode wear, and substitutes electrodes automatically based on programmed criteria.
03
The NX 10 supports Erowa and System 3R tooling interfaces as standard, enabling integration with robotic pallet handling and electrode loading systems from these manufacturers. This allows the NX 10 to operate as part of automated manufacturing cells with minimal operator intervention.
04
Yes. The NX 10 provides OPC-UA and MTConnect interfaces for standard machine data communication. These protocols enable process data collection, remote monitoring, and integration with plant-level MES and ERP systems, supporting quality traceability requirements in aerospace and medical manufacturing.
05
The NX 10 is ONA's top-tier sinker EDM with a larger work envelope (450×350×400 mm vs. 350×250×300 mm), higher generator amperage (128 A vs. 64 A), finer achievable finish (Ra 0.1 µm vs. 0.2 µm), and full automation integration features. The NX 10 is chosen when the highest accuracy, finest finish, and automated cell operation are required; the AX 350 is the value choice for precision mid-size cavity work.
