The chuck is a mechanical device on the machine tool to clamp the workpiece; and a machine tool accessory that can clamp and position the workpiece firmly by use of the radial movement of movable jaw uniformly distributed on the chuck. It is learned that a chuck is composed of chuck body, movable jaw and jaw driving mechanism three parts. The diameter of a chuck can range from 65mm to 1,500mm. There is a through hole in the center, which facilitates the workpiece or barstock to pass through; and the back of the chuck has a cylindrical or short taper-shape structure, which can be connected to the end of the shaft of the machine tool via a flange plate. The chuck is usually installed on the lathe, cylindrical grinder and internal grinder and can also be used together with all kinds of dividing apparatuses on millers and drillers.
