Deep Cavity EDM Specialist: Extended Reach Chuck for Complex Mold Manufacturing​

The ​PA-14002N Quick Chuck 50 with Extension Rod​ builds upon our PA-14001N design to solve a critical challenge in mold manufacturing: accessing deep cavities and complex geometries. While maintaining full compatibility with EROWA ER-034387 systems, this extended version provides the additional reach needed for sophisticated EDM operations where standard chucks cannot access.

​Key Advantages vs. Standard EROWA ER-034387:​​

• •

  ​📏 167.2mm Extension Rod:​​ Provides exceptional reach into deep mold cavities and complex geometries, enabling EDM processing of areas inaccessible to standard quick chucks

• •

  ​🛡️ Complete Rust-Proof Construction:​​ 100% Nippon Stainless Steel construction (57-60 HRC) ensures corrosion resistance in coolant-intensive EDM and wire-cut environments

• •

  ​⚡ Quick-Change Compatibility:​​ Maintains identical mounting pattern and 4000N clamping force of the ER-034387 for seamless integration with existing systems

• •

  ​🎯 Precision Performance:​​ Guarantees <0.002mm repeat accuracy for critical EDM and precision machining applications

• •
