Adjustment Of The Tailstock; Adjusting The Tool Rest - Holzstar DB 900 Operating Instructions Manual

Fig. 12: Adjustment of the spindle head
Step 1: Do not turn the spindle head counterclockwise
when it is in this position (Pos. 1, Fig.12).
Step 2: Do not turn the spindle head clockwise when it is
in this position (Pos. 2, Fig.12).
With the lathe DB 1100, you also have the option of mo-
ving the spindle head on the machine bed after releasing
the spindle head clamp (Figure 13).

Fig. 14: Adjustment of the tailstock
After releasing the tailstock clamping lever (Pos. 1, Fig.
14), the tailstock can be moved on the machine bed as
required.
To clamp a long workpiece between centres, clamp the
tailstock to the clamping lever (pos. 1, Fig. 14). Turn the
tailstock spindle on the handwheel out until the travelling
centering point is pressed sufficiently deep into the work-
piece to be machined. This should protrude approx. 20
mm from the tailstock. Clamp the spindle to the lever
(Pos. 3, Fig. 14). Check by hand whether the workpiece
is firmly seated.
NOTE!
Adjust the lace from time to time during machining to

9.5 Adjusting the tool rest

Fig. 15: Adjusting the tool rest
Use the tool rest for safe guidance of the lathe tool and
as a support for the hand. A distance of approx. 1-3 mm
must be set between the workpiece and the tool rest. Ad-
just the tool rest approx. 3 mm below the axis of rotation.
Thinner workpieces can also be worked without an ex-
tension arm (Pos.1, Fig.15). Insert the tool rest (Pos.2,
Fig.15) directly into the traverse slide (Pos. 3, Fig. 15).
By releasing the clamping lever (Pos.4, Fig.15), the travel
carriage can be moved on the machine bed as required.
When machining larger workpieces, the tool rest with ex-
tension arm must be mounted to the left of the headstock
(Figure 16).

Finally tighten all clamping levers.
Turn the workpiece several times by hand to check the
settings and avoid collisions.

For an optimal lathe turning result, perfect and shar-
ply ground tools must be used.
