摘要： A chuck comprises a mounting base 11, and a protruding shaft 12 protruding from a center of a front surface of the base and having a tapered surface 13 on the outer peripheral surface thereof. A hole 16 is formed in the protruding shaft and has an opened end surface, and the hole has holding portions 14 and pressure portions 15. The holding portions and the pressure portions are alternately arranged, and the holding portions are situated at a plurality of positions evenly spaced about an inner periphery of the shaft 12, and each of the holding portions has a short radius from the center of hole 16. The pressure portions are situated between the holding portions and have a long radius from the center of hole 16. A rotating cylinder 20 is detachably fitted outside the protruding shaft, and a group of rollers 21 is arranged inside the rotating cylinder that the axis of the group of rollers is aligned along the axis of the rotating cylinder and so that they are supported by appropriate means. The rotating cylinder is rotated, whereby the tool is held and removed.

摘要： A needle-roller type chuck for machine tools which includes a chuck body having a chuck barrel integral with the leading end portion of the chuck body. The chuck barrel has a leading end portion and an outer peripheral surface tapered to form a conical surface, and includes a plurality of holes extending from the leading end of the chuck barrel toward the chuck body. A rotatable clamping ring is positioned over the chuck barrel and has an inner conical surface extending in the axial direction of the chuck and parallel with the outer periperal surface of the chuck barrel. A needle-roller assembly having a plurality of needle rollers is positioned between the chuck barrel and the clamping ring in rotatable contact with the conical surface of the chuck barrel and the clamping ring.
