ABSTRACT:
A centrifugal force compensation device in a wedge-type balanced rotary chuck having jaws comprises, for each jaw, a balance weight and means for doubling the centrifugal force acting on the balance weight and applying the doubled force to the back face of that jaw near the outer periphery thereof thereby to press forward the jaw and impart thereto a moment urging it to rotate inward toward the chuck axis, whereby the so-called jaw flotation phenomenon is countered and prevented and, simultaneously, the reduction in chuck gripping force due to centrifugal force is compensated for.
