Lathe Machine Three-Jaw Compensating Chuck - 3W

The center compensation-type three-jaw chuck is designed for securely swinging and grasping workpieces, making it ideal for materials such as castings and forgings. It is particularly suitable for heavy machining applications. The chuck is sealed to protect against dust and cutting fluid, ensuring convenience during maintenance. Swing parts are heat-treated, hardened, and ground from steel to enhance durability and extend product service life. It offers a workpiece eccentric compensation of 2 mm, with a fixed position for the center thimble. Additionally, soft jaws and grippers are optional, and O.D. (outer diameter) and I.D. (inner diameter) gripping can be interchanged to meet various processing requirements.
