High Precision Expansion Pin for CNC Fixtures and Workholding Applications

Body:SUS630 HRC34

Tapered bolts:Steel (strength class 12.9) Oxygen resin coating

This High Precision Expansion Pin delivers exceptional accuracy for CNC fixtures and workholding applications. Engineered with a precision-ground taper and advanced expansion mechanism, it provides secure, vibration-free clamping with repeatable micron-level accuracy. The pin's unique design ensures uniform radial expansion for perfect concentricity, making it ideal for locating and securing components in machining operations. Manufactured from hardened, heat-treated steel, it withstands rigorous production environments while maintaining long-term dimensional stability. The quick-expansion feature dramatically reduces setup time while providing consistent clamping force, making it an essential component for high-volume precision machining of gears, bearings, and other critical components in milling, grinding, and turning applications.
