Precision Macro-Style Manual Spigot for Reliable Workholding
The PA-21003V-TR is a high-quality manual spigot (drawbar) designed for Macro-style manual clamping systems. It serves as the critical connecting element between centering plates, pallets, or reference elements and the manual chuck, providing secure locking and repeatable positioning.
Manufactured from hardened stainless steel (HRC 48–52) , this spigot offers exceptional wear resistance and dimensional stability under repeated clamping cycles. The precision-ground surfaces ensure consistent engagement and reliable locking force.
A key feature of this spigot is the integrated Ø7mm flushing hole, which allows coolant, compressed air, or EDM dielectric fluid to pass through the assembly. This is particularly valuable in EDM applications where efficient flushing is essential for optimal machining performance and surface finish.
Key Benefits:
Secure Locking: Designed to provide reliable clamping force when used with Macro-style manual chucks.
Flushing Capability: Ø7mm through-hole enables fluid or air passage, supporting EDM and machining operations.
Durable Construction: Hardened stainless steel withstands wear and maintains accuracy over long-term use.
Complete Assembly: Supplied with all necessary plastic components for easy installation.
Cost-Effective: A practical alternative for expanding or maintaining existing Macro-style manual systems.
Typical Applications:
Securing centering plates or pallets in Macro-style manual chucks
EDM electrode and workpiece mounting requiring through-fluid flushing
Manual workholding setups in milling, grinding, and EDM operations
Compatibility: The PA-21003V-TR is designed for use with manual chucks and clamping systems utilizing the industry-standard Macro-style interface. It is intended as a direct replacement for spigots used in such systems.
Note: This spigot is the short type version. For applications requiring different lengths, please consult system specifications or contact our technical support.
