Precision Macro-Style Centering Plate for Electrode & Workpiece Mounting

The PA-21001V-TR is a high-precision centering plate designed for use in Macro-style reference systems. It serves as the interface between the workpiece or electrode and the chuck (either manual or pneumatic), ensuring repeatable positioning and quick changeover in automated or semi-automated machining cells.

Manufactured from Stainless Steel 420 and hardened to 40–44 HRC, this centering plate offers excellent wear resistance, dimensional stability, and corrosion protection. The precision-ground surfaces guarantee reliable seating and consistent reference positioning, critical for achieving high accuracy in electrode erosion and workpiece machining.

Key Benefits:

• Seamless Integration: Designed to interface with Macro-style chucks and pallet systems, making it suitable for expanding existing automation setups.

• Durable Construction: Hardened stainless steel ensures long service life even under frequent clamping cycles.

• Consistent Accuracy: Precision-ground geometry provides reliable reference surfaces, supporting repeatability within the tolerance limits of the overall system.

• Cost-Effective Alternative: Offers a practical solution for users seeking high-quality reference elements without compromising on performance.

Typical Applications:

• Mounting copper or graphite electrodes for EDM

• Workpiece holding for milling, turning, or grinding

• Integration into automated tooling systems requiring 54×54mm Macro-style interfaces

Note: For graphite electrode applications, a spacer plate may be required depending on the chuck and electrode geometry (refer to system requirements).

Compatibility: The PA-21001V-TR is designed to function with chucks and automation systems utilizing the industry-standard 54×54mm Macro interface. It is suitable for both manual and pneumatic clamping units.
