Precision Macro-Style Centering Plate for Larger Electrodes & Workpieces

The PA-21002V-TR is a precision centering plate designed for Macro-style reference systems requiring a 70×70mm interface. It serves as a robust pallet or reference element for mounting larger electrodes, workpieces, or fixture plates onto compatible chucks (manual or pneumatic). This size is commonly used when additional stability or larger part capacity is needed.

Manufactured from Stainless Steel 420 and hardened to 40–44 HRC, the PA-21002V-TR provides excellent wear resistance, corrosion protection, and long-term dimensional stability. The precision-ground surfaces ensure repeatable seating and consistent reference positioning, critical for high-accuracy EDM or milling applications.

Key Benefits:

• Expanded Capacity: 70×70mm footprint accommodates larger electrodes or workpieces than standard 54×54mm plates.

• Seamless Integration: Designed for use with Macro-style chucks and automation systems, enabling quick changeover and flexible production.

• Durable Construction: Hardened stainless steel withstands repeated clamping cycles without deformation.

• Cost-Effective Alternative: Offers a high-quality reference element at a competitive price point.

Typical Applications:

• Mounting larger copper or graphite electrodes for EDM

• Workpiece holding for milling, turning, or grinding operations

• Building custom fixture plates using the 70×70mm Macro interface

Compatibility: The PA-21002V-TR is designed to function with chucks and automation systems utilizing the industry-standard 70×70mm Macro interface. It is suitable for both manual and pneumatic clamping units.

Note: For specific system requirements (e.g., clamping force, air pressure), refer to your chuck manufacturer’s specifications.
