Which lathe part carries a graduated rule for measuring the axial movement of the tool into the workpiece?

• A. Tailstock sleeve
• B. Carriage
• C. Cross slide
• D. Feed rod

Answer: (A)

The tailstock sleeve is the part that carries a graduated rule for measuring how far the tool extends into the work along the axis. The tailstock houses the quill, which can push a drill or center into the work, and the sleeve’s graduations let you read the exact axial extension of that tool. This direct readout of depth into the work isn’t provided by the carriage or cross slide, which control movement along and across the axis, or by the feed rod, which handles automatic feeding.
