In this paper, the effect of bending load on bending stiffness of a wedge-type power chuck with three top jaws is investigated. Bending tests of works with different diameters were performed in which the deflection of works were measured. The investigation showed that the bending stiffness of the chuck-work system significantly depends on the bending load when the bending load is increasing. The bending stiffness varies with gripping force and the ratios of the diameter of works to the gripping length of jaws. There is no effect of the bending load on the bending stiffness when works are clamped under the gripping condition in which gripping lengths are 0.8 times an large as work diameters. This gripping condition is also acceptable for the damping efficiency of the system.
