DIAPHRAGM COLLET CHUCK

A Diaphragm Collet Chuck is a high-precision workholding solution designed for exceptional concentricity and minimal workpiece distortion. Using an integral elastic diaphragm for uniform 360° clamping, it delivers micron-level repeatability, making it ideal for finish turning, grinding, and tight-tolerance CNC machining where superior roundness and surface finish are critical.

Diaphragm Collet Chuck is a high-precision workholding solution engineered for exceptional concentricity and minimal workpiece distortion. The chuck uses an integral elastic diaphragm that flexes uniformly to grip the component, delivering micron-level repeatability—ideal for finish turning, grinding, and tight-tolerance CNC operations.

Unlike segmented collets, the diaphragm design provides continuous 360° contact, ensuring superior roundness, surface finish, and consistency in high-accuracy production.
