ONA AX 350 CNC Sinker EDM

The ONA AX 350 is a high-performance CNC sinker EDM machine engineered for demanding production environments where throughput, surface quality, and unattended operation are critical. Designed for aerospace, automotive tooling, and precision mold manufacturing, the AX 350 combines ONA’s advanced generator technology with a rigid machine structure and comprehensive automation-ready interface.

At the heart of the AX 350 is ONA’s AIC (Adaptive Intelligent Control) generator, which uses real-time gap monitoring and adaptive algorithms to continuously optimize pulse parameters throughout the erosion cycle. This technology maximizes material removal rates during roughing while automatically transitioning to fine-finish parameters as the target depth is approached, reducing total machining time without operator intervention.

The machine features a large work tank accommodating substantial mold bases and aerospace structural components, with a dielectric system capable of maintaining precise fluid temperature for thermally sensitive finishing work. Its C-axis rotary attachment option enables rotational erosion of turbine blade slots, fuel injector bodies, and other complex geometries that require coordinated electrode rotation.

The AX 350’s ONAWIN control provides full remote monitoring capabilities, job queue management, and integration with electrode management systems for extended lights-out operation. ONA’s global service presence and their reputation for long machine lifespans make the AX 350 a strong long-term investment for mold shops and aerospace suppliers.
