Tailstock
The tailstock is typically used to support long
workpieces at the side opposite the spindle, using
a live or dead center. It can also hold a tapered
drill bit (or a drill chuck with a regular drill bit)
for boring holes. Unlike boring done with a drill
press where the workpiece is fixed and the drill
bit rotates, the drill bit in a tailstock remains
stationary while the workpiece is rotated by the
spindle.
The entire tailstock can be repositioned and
locked in place along the length of the bed. An
independently controlled offset adjustment
allows the upper part of the tailstock to move
perpendicular to the bedways so it can be aligned
with the spindle center (for concentric turning)
or offset from the spindle center (for tapered
turning).
The tailstock quill also features independent
adjustment controls that allow it to be advanced
toward the spindle or locked firmly in position.
