A three-jaw self-centering chuck is a clamping device used on lathes and other machine tools that holds a workpiece by using three jaws that move simultaneously to the center of the workpiece. It is constructed with a scroll gear mechanism that ensures all jaws move together for quick and accurate centering. These chucks are durable, often made of materials like hardened steel or cast iron, and feature reversible jaws for both internal and external clamping.
