Tailstock - Scheppach Lata 5.0 Traduction Du Manuel D'origine

Driver, Fig. 1.2, A
The driver is used exclusively for work between both
centers.
Face plate, figure 1.1
The face plate is used with flat larger tools.
Change of the clamping tools
• Loosen grub screw on the shaft of the clamping tool.
• Retain spindle with mandrel, release the clamping tool
with the hexagonal spanner.
Headstock, figure 9
• The headstock can be swivelled after releasing the
clamping handle and pulling the locking bolt up to 180°
(engagement positions 60°/90°/135°/180°).
• The headstock must be clamped again in each posi-
tion.
• The headstock is to be adjusted in the released posi-
tion on the drilling bed in order to attach the tool rest
from the left onto the tailstock.
• These positions enable you to process tools with larger
diameters.

Tailstock

• Once the eccentric clamp has been loosened, the tail-
stock can be moved over the entire length of the bed
and can be secured at any distance from the head-
stock.
• To insert a workpiece between the centers, loosen the
binder, turn the sleeve approx. 20 mm outward and
clamp.
• Slide the tailstock to the workpiece and place the tail-
stock center into the sunken point in the center of the
workpiece.
• Screw out the tailstock sleeve until the tailstock center
rests securely in the wood. Retighten the binder.
• Turn the workpiece to see if it rests securely between
the two centers and can be rotated freely.

• Loosen the binder (5).
• Turn tailstock spindle sleeve totally backwards until
the tip can be removed.
Tool holder, Fig. 9, 10
• The tool holder both insures safe use of wood turning
tools and at the same time serves as a support for the
hand.
• The height of the tool holder can be adjusted once the
binder has been loosened. To turn further, pull in the
direction indicated by the arrow.
• Place the tool holder at a distance of 1 – 3 mm from the
workpiece. Check the adjustment in addition to rotating
the workpiece by hand.
• Set the tool holder ca. 3 mm above the axis of the
workpiece.
• Check the adjustment once again by rotating the work-
piece by hand.
• Once the eccentric clamp has been loosened, the
holder console can be moved along the entire length of
the bed and in the direction perpendicular to the work-
piece. Furthermore, the holder console can be tilted
over approx. 45º to either side.
• To work with a plane surface, turn the tool holder 90º
and place up against the surface to be worked. De-
pending on the wood turning tool, place the tool holder
up to 6 mm underneath the axis of the workpiece.
• If the headstock is swivelled, then the tool rest with the
extension is to be used (Fig. 11).
• Therefore it is inserted from the left of the headstock so
that larger discs can be processed.

the most frequent forms. Once the machine has been
plugged in, it is ready to be used. Observe the operating
instructions in „Electrical connection".
Operations
A perfect and sharp wood turner tool is a precondi-
tion for professional wood-turning.
Selection of materials
• Wood to be turned must be of good quality and with-
out imperfections such as fissures against the grain,
a marred surface, or knots. Faulty wood tends to split
and becomes a risk for both the operator and the ma-
chine.
• Workpieces that have been glued together should only
be processed by experienced craftsmen. Because the
workpiece can explode as a result of developing cen-
trifugal force, turning such wood demands careful glu-
ing without weak points.
Note: Beginners should first master fundamental skills by
working exclusively with solid material.
Preparation of the materials
• To turn long pieces of wood, the material must be cut
into a square form beforehand.
• To turn a cross-arm, the material must be cut to size in
its natural state as well. Saw out the rough form with a
band saw. An octagonal form is recommended for the
material so that vibrations are reduced.
Centering of the workpiece (Fig. 12)
Centering the prepared workpiece is an important opera-
tion to be performed before placing it into the machine.
Centering consists of measuring the middle point of the
workpiece and marking it with a center punch.
Make a depression of 1.5 to 2 mm in the middle point.
If the workpiece has not been centered exactly, strong
vibrations will develop as a result of the imbalance. It is
possible that the workpiece could be hurled outward as
a result.
NOTE: Exact centering of the workpiece produces
smooth concentricity.
While working with the turner
• Work with a rough workpiece should be conducted at
low speeds.
• Only after the wood has been pre-turned (the pre-turn-
ing operation is complete once the basic form of the
workpiece as well as an even concentricity have been
achieved) can the speed be raised.
• The live center must be readjusted from time to time
with the hand wheel. This operation only should be
performed when the motor has been turned off.The
tailstock center should rest firmly in the wood.
• Turn the workpiece by hand to check if it rests secured.
