Lathes have four main components&colon; the bed, the headstock, the carriage, and the tailstock. A tailstock has a Dead Center, while headstock has Live Center. The tailstock is a tool (drill), and centre mount, opposite the headstock. These machines consist of (at the least) a headstock, bed, carriage, and tailstock. The tailstock was also of completely new design. A Tailstock is particularly useful when the workpiece is relatively long and slender.
