E-Series Automation Chuck
Precision for Automated Manufacturing
The Nextas E-Series Chuck is the definitive solution for high-precision, automated manufacturing. Fully compatible with the EROWA ITS system, this chuck provides a universal interface for electrodes and workpieces across various processes like EDM, milling, and grinding. Its robust design and exceptional repeatability make it the cornerstone of any modern, flexible production environment.
Product Details
The Nextas E-Series Chuck operates on a proven principle of precision and reliability. The chuck's internal mechanism, actuated by compressed air, opens the clamping collet to accept a workpiece holder or electrode. When the air is released, the collet closes with immense force, pulling the holder into a precise, repeatable Z-position against the hardened contact surface. This system not only ensures accuracy but also allows for rapid, automated changes, forming the backbone of a "set up once, machine anywhere" production philosophy.

Built for Durability and Automation
Manufactured from high-grade, rust-proof stainless steel, the E-Series Chuck is engineered to withstand the demanding conditions of EDM and grinding operations. Its sealed design prevents ingress of dielectric fluid and abrasive particles. Integrated connections for air pressure, cleaning, and presence check functions allow for seamless communication with robotic handlers and machine controllers, making it a truly "plug-and-play" component for any automation cell.

Application Cases

EDM (Electrical Discharge Machining)
The corrosion-resistant construction and high precision make it the industry standard for holding electrodes and workpieces in die-sinking and wire-cut EDM machines.

High-Speed Milling
Provides a rigid, stable base for high-speed milling operations. Workpieces can be pre-set offline on pallets and quickly loaded into the machine, maximizing spindle uptime.

Grinding & Jig Grinding
The exceptional repeatability is critical for precision grinding operations, ensuring ultimate accuracy for tight tolerances and fine surface finishes.

Tool & Mold Making
The ability to move a workpiece between different technologies on the same holder is a game-changer, drastically reducing lead times and improving accuracy.
