CNC Expansion Clamp Expanding Mandrel Fixture 140mm 165mm For Internal Bore Clamping

High Performance CNC Expanding Mandrel Fixture for Internal Bore Clamping Applications

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 High-Performance CNC Expanding Mandrel Fixture delivers exceptional precision for internal bore clamping applications. Engineered with a precision-ground taper and high-rigidity expansion segments, it provides uniform radial pressure for secure, vibration-free gripping of cylindrical workpieces. The design ensures perfect concentricity within microns, eliminating runout for critical bore machining operations. Ideal for gears, bearings, and precision components, its quick-expansion mechanism slashes non-cutting time while maintaining consistent clamping force. The hardened construction guarantees long-term accuracy and reliability in high-volume production, making it an essential solution for maximizing productivity in turning, grinding, and milling applications requiring internal workholding.
