Tailstock
The tailstock serves as a counter bearing when turning between
the centres as well as for holding drilling, countersinking and
reaming tools. It is guided on the cheeks of the machine bed
and can be clamped at any point by a clamping lever (2).
The tailstock is secured in the machine bed (cast bed) with an
end position stop screw (1) to prevent the tailstock from sliding
out unintentionally (see picture on the left).
The tailstock spindle sleeve (1) can be moved by a threaded
spindle and a handwheel (3) and can be clamped with a
clamping lever (2). An inner taper in the quill accommodates the
centering point, a drill chuck or tools with a tapered shank.
•
Clamp your required tool into the tailstock sleeve.
→
Use the scale on the sleeve for adjustment and/or
readjustment.
•
Clamp the sleeve with the clamping lever.
→
Use the handwheel to retract and extend the quill.

Tailstock laterally offset
The transverse displacement of the tailstock is necessary, for
example, when turning long, conical bodies.
Loosen the tailstock clamping lever (1) and the adjusting screws
(2) on the left and right of the tailstock.
The desired transverse offset can be set with the help of the
scale on the back of the tailstock.
Finally retighten adjusting screws and clamping lever.
