FLANGE TYPE EXPANDING SHAFT

Asmita Industries is a leading Flange Type Expanding Shaft manufacturer in India, offering precision-engineered expanding shafts for accurate internal clamping applications. Designed for high concentricity and rigidity, our flange-mounted expanding shafts ensure stable, vibration-free machining for repetitive production.

A Flange Type Expanding Shaft is an internal workholding device used to clamp components from the inside diameter (ID). The flange mounting provides rigid axial positioning and easy installation on machines like CNC lathes, VMCs, grinding machines, and special purpose machines (SPMs).

When actuated (manual, pneumatic, or hydraulic), the expanding segments uniformly expand to grip the bore, ensuring excellent concentricity and repeatable accuracy.
