Abstract
The paper deals with the experimental research of clamping surface deformation zone of adaptive clamping jaw to equip lathe jaws chucks during machining work pieces of different diameters. The directly proportional displacement dependence on clamping force for the most deformed part of clamping zone ring segments in work pieces of different diameters machining is obtained. The results of experimental research have verified the theoretical calculations and showed that clamping part of adaptive jaw is being deformed sufficiently for full fitting of the clamping jaw surface and the work piece.
