Open Centre Power Chuck

An open center power chuck is a type of chuck that features a hollow center or opening through which workpieces can pass. This design allows for the machining of longer or larger workpieces that extend beyond the chuck's gripping jaws. They are commonly used in applications where the workpiece needs to be machined on both ends or where a bar or shaft needs to pass through the chuck for continuous machining operations.
