Precision Checking Pin for Macro-Style Chuck Setting & Verification

The PA-21009V-TR is a high-precision checking pin (control rod / mandrel) designed for use with Macro-style chucks and automation systems. It is an essential tool for setting, verifying, and calibrating chuck accuracy, ensuring that your workholding system maintains optimal performance.

This checking pin features precision-ground C-reference surfaces that provide reliable alignment references for chuck setup. The 54×54mm base interface allows it to be loaded into the clamping system just like a standard pallet or electrode holder, enabling straightforward integration into existing setup routines.

Manufactured from hardened stainless steel (HRC 48–52) , the PA-21009V-TR offers exceptional wear resistance, dimensional stability, and long service life even under frequent shop floor use. The reference surfaces are precision ground to achieve a parallelism tolerance of ±0.005mm, ensuring consistent and repeatable measurement results.

Key Benefits:

• Accurate Chuck Setting: Provides reliable reference for centering and aligning Macro-style chucks.

• Calibration Tool: Ideal for verifying chuck accuracy and detecting wear over time.

• High Precision: ±0.005mm parallelism tolerance ensures dependable measurement results.

• Durable Construction: Hardened stainless steel withstands repeated use in demanding environments.

• Easy Integration: Standard 54×54mm interface works seamlessly with existing Macro-style clamping systems.

• Cost-Effective: Offers a practical alternative for users seeking quality setup tools without premium pricing.

Typical Applications:

• Setting and centering Macro-style chucks during machine installation or maintenance

• Verifying chuck accuracy and repeatability

• Calibrating automation workholding systems

• Quality control and periodic accuracy checks

• Training and setup verification in manufacturing cells

Compatibility: The PA-21009V-TR is designed for use with Macro-style chucks and clamping systems utilizing the industry-standard 54×54mm interface. It serves as a reliable reference tool for systems requiring precise chuck alignment.

Note: For optimal accuracy, ensure that the reference surfaces are clean and free from debris before use. Regular calibration checks using this mandrel can help maintain consistent machining quality over time.
