Guide To CNC Chuck Jaws: Soft Jaws vs. Hard Jaws
soft jaws are more adaptable but wear out faster, while hard jaws are more durable but less flexible for customizing the fit of the workpiece. ...

A 4 jaw chuck is a workholding device commonly used on lathes for both metalworking and woodworking. Its distinguishing feature is four jaws that can be adjusted independently (in independent chucks) or simultaneously (in scroll-type chucks).
Holding Irregularly Shaped Workpieces: Each jaw moves independently, allowing secure clamping of square, rectangular, hexagonal, or asymmetric pieces—something not possible with standard 3 jaw chucks.
Precision Centering: The independent adjustment provides high accuracy in centering workpieces. This makes the 4 jaw chuck ideal for tasks requiring tight tolerances.
Eccentric or Off-Center Turning: Unlike 3 jaw chucks, a 4 jaw allows deliberate off-center clamping, enabling the machining of cams, crankshafts, or other eccentric forms.
Enhanced Grip Strength: 4 jaw chucks typically clamp stock tighter than 3 jaw chucks, which is beneficial when working with delicate materials or thin-walled tubing where load distribution minimizes deformation.
Machining Versatility: They are used extensively in manufacturing for turning operations on lathes, and in woodturning for crafting items like bowls and spindles. The capability to grip odd shapes expands their application range in both metal and woodworking.
