What Is a Lathe Chuck?
A lathe chuck is a device attached to the spindle of a lathe, designed to secure the workpiece.
There are three main types of lathe chucks: 3-jaw chucks, 4-jaw chucks, and collet chucks. The 3-jaw chuck, the most common type, features three jaws that move simultaneously to grip the workpiece, ensuring concentricity. The 4-jaw chuck, with its independent jaws, is more suitable for clamping non-axisymmetric workpieces. Collet chucks, ideal for small-diameter workpieces and precision operations, secure the workpiece using a cylindrical collet.
In operation, the workpiece is placed into the chuck, and the tightening handle is turned to secure it before starting cutting operations. Lathe chucks are essential in lathe operations, enabling safe and efficient work when used correctly.
