The carriage of a lathe is the assembly that supports, moves, and controls the position of the cutting tool during machining operations. It travels along the bedways, parallel to the axis of the spindle, and allows for precise movement of the tool relative to the rotating workpiece. The carriage consists of several key components—including the saddle, cross-slide, compound rest, tool post, and apron—each playing a role in guiding and positioning the tool.
Together, these components enable the carriage to perform a wide range of operations such as turning, facing, and threading. The carriage can be moved manually using handwheels or powered by the lathe’s feed system. Its stability, alignment, and smooth motion are essential for producing accurate cuts and maintaining tight tolerances. As the primary structure that controls tool movement, the carriage is one of the most functionally important parts of the lathe.
