Expanding Flange Collet Chuck is a precision internal gripping workholding system designed to hold components from the inside diameter (ID). The collet expands radially against the bore while the flange face provides positive axial location, ensuring excellent concentricity, face squareness, and distortion-free clamping.
This chuck is ideal for thin-wall rings, bushings, bearing housings, flanged parts, and components where external clamping is not possible. Suitable for CNC lathes, turning centers, and grinding machines, it delivers repeatable accuracy for high-precision production.
