E-Catalog > SMW AUTOBLOK > D-Chuck for Hard Turning of Gears

SMW Autoblok’s D-Chuck is a high accuracy, quick jaw change diaphragm chuck for hard turning gears. The elastic deformation of the D-Chuck’s diaphragm provides constant, adjustable clamping force with extremely high precision. No sliding parts in the clamping system contributes to greater precision, and also to reduced maintenance and longer chuck life thanks to the absence of friction.

The quick jaw change system utilizes the ABS® Coupling (licensed from Komet), which offers high rigidity and accuracy. Jaws can be changed in less than one minute, facilitating fast changeover between jobs. Matched jaw sets can be used on different D-Chucks with no loss of accuracy.

To compensate for the centrifugal force caused by the jaws during operation, counter balance weights connected to the clamping jaws are mounted underneath the diaphragm.
