Precision ID Expansion Mandrel for CNC Clamping Fixture Workholding Solutions

Segmented clamping mandrels with hardened steel segments are particularly suitable for clamping workpieces with internal geometries.
Main applications include turning, grinding, milling, tool cutting, balancing, centering, and boring.

This Precision ID Expansion Mandrel delivers exceptional accuracy for internal workholding applications. Engineered with a precision-ground taper and high-rigidity expansion mechanism, it provides uniform clamping force for secure, vibration-free gripping of bores and cylindrical workpieces. The design ensures perfect concentricity within microns, eliminating runout for critical internal machining operations. Ideal for gears, bearings, and precision components, its quick-expansion mechanism dramatically reduces setup time while maintaining consistent clamping force. The hardened, heat-treated construction guarantees long-term accuracy in high-volume production, making it an essential CNC workholding solution for maximizing productivity in turning, grinding, and milling applications requiring internal clamping.
