Accutex AU-iA Series – Fixed Table Moving Column Submerged-Type Extra Large Capacity Wire EDM

Accutex Edm Logo

The AccuteX AU-iA Series are large fixed-table, submerged-type, extra-large capacity wire EDM machines designed to handle heavy workpieces with exceptional cutting performance and precision. Uncommon in today’s market, the AU-iA Series delivers massive-scale capacity and features automatic wire threading over the full stroke, accommodating workpieces up to 31.3 inches in height.

Each machine is designed using Finite Element Analysis (FEA) for maximum structural integrity, featuring a Meehanite honeycomb-type base, heavily ribbed column, and reinforced lower arm that ensure rigidity and long-term accuracy under heavy-load conditions. Combined with AccuteX’s Intelligent AWT system, C1-class ball screws, and linear glass-scale feedback, the AU-iA Series achieves sub-micron precision, ultra-fine surface finishes, and reliable unmanned operation for demanding aerospace, medical, and mold & die applications. Competing directly with Mitsubishi, Makino, GF Machining Solutions, Sodick, and Fanuc, AccuteX offers a powerful, cost-effective alternative for precision EDM manufacturing.

Benefits for Metal Cutting Manufacturers

  • Unmatched Structural Rigidity: FEA-engineered Meehanite castings and reinforced lower-arm design minimize vibration and deflection during long EDM cycles.
  • Sub-Micron Motion Accuracy: Closed-loop AC servomotors, C1-class ball screws, and Fagor glass scales deliver consistent positional accuracy even on tall or heavy parts.
  • Reliable Full-Stroke Threading: The Intelligent AWT System automatically rethreads at the wire break point anywhere along the stroke for uninterrupted cutting and maximum uptime.
  • Superior Spark Control: The SD Master EPGA discharge circuit stabilizes spark energy, improving surface finish quality and reducing cycle times.
  • User-Friendly CNC Interface: The Windows-based 64-bit control with a 15″ color touch screen offers conversational setup, built-in cutting data, and easy operator training.
  • Thermally Stable Operation: Dual dielectric tanks with automatic temperature and conductivity regulation maintain consistent machining conditions.
  • Large-Scale Productivity: The submerged-type configuration enables efficient flushing and precision cutting of extra-large workpieces.

These benefits help manufacturers achieve higher part accuracy, reduced cycle times, and repeatable quality, maximizing throughput and profitability.
