What is the chuck tip and what is its principle?

Working principle of the driving center: The driving center is a new type of machine tool accessory. By embedding the driving claw into the end face of the workpiece, the spindle of the random bed rotates, thus replacing the traditional heart-shaped chuck and chuck. It is suitable for one-time clamping and full-length machining of shaft parts. Chuck is a mechanical device for clamping workpieces on machine tools. A machine tool accessory that clamps and positions a workpiece by using the radial motion of movable claws evenly distributed on the chuck body. Chuck is generally composed of chuck body, movable jaw and jaw driving mechanism. The minimum diameter of the chuck body is 65 mm, the maximum diameter is 1500 mm, and there is a through hole in the center for the workpiece or bar to pass through; The back is a cylindrical or short conical structure, which is connected with the end of the machine tool spindle directly or through a flange.

Chuck is usually installed on lathe, cylindrical grinder and internal grinder, and can also be used on milling machines and drilling machines with various indexing devices. The driving center has a special tip and is uniquely designed for various machine tools. Driving centers for turning, grinding and gear machining can be used in various occasions. The center adopts patented dynamic balance and automatic compensation system, which can still be processed even if the tip of the tool points at the blank parts or inclined planes. There are three ways to connect with the machine tool: Morse taper handle, flange connection and soft claw clamping, which are convenient and reliable to install and use. In finishing and grinding series, the fixed connection of the center center can accurately locate the axial dimension. With different specifications of driving paddles, shaft sleeve parts with an outer diameter of 5-400 mm or even larger can be processed.
