Description

This Ø95x75mm Internal Expansion Lock is designed for precision CNC workholding applications where a workpiece needs to be held securely from an internal bore. The internal expansion clamping design allows the outside surfaces of the part to remain more accessible, making it useful for 5-axis machining, multi-sided machining, EDM workholding, and inspection setups.

Made from hardened chrome steel, the holder provides rigidity, wear resistance, and stable performance during repeated production use. The Ø30–32mm expansion range is suitable for precision bore clamping applications and can be customized based on specific workpiece requirements. With ≤0.01mm repeatability and a bottom zero point bolt interface, this internal expansion lock supports accurate fixture positioning, faster setup changes, and dependable performance in precision machining environments.
