18.8 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 tailstock sleeve.
18.8.1 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.
18.9 General working instructions
W A R N I N G
Do not clamp workpieces that exceed the permissible clamping range of the
workpiece holders, machine chucks, etc. The clamping force of a machine chuck is
too low when the clamping range is exceeded. The clamping jaws can become loose.
C A U T I O N
Regularly check the closed condition of the clamping bolts.
The workpieces must be clamped securely and firmly on the machine before machining. The
clamping force should be dimensioned in such a way that the workpiece can be securely gripped,
but no damage or deformation of the workpiece occurs.
