Caution!
Avoid abnormal body posture! Make sure you stand securely and
can keep your balance.
Caution!
Only work with a folded down chuck guard! If the guard is de-
fective, the machine may no longer be operated!
Example of straight turning (a)
Note:
Turning parallel to the rotary axis and machining cylindrical ob-
jects are the main applications of a lathe.
1. Clamp the workpiece as described in the chapter "Clamping
the workpiece".
2. Make sure that the workpiece can be turned freely.
3. Set the necessary rotational speed by shifting the belts in the
gear case (see previous section). Caution: Turn the rota-
tional speed regulating knob to the left before switching on.
4. Clamp the appropriate tool in the tool holder (see "Clamp-
ing the cutting tool").
5. Move the support to the workpiece from right to left.
6. Set the cutting depth with the cross slide 1.
7. Move the cross slide and upper carriage up to the work-
piece.
8. Switch on the machine using the master switch. Caution:
Make sure that the chuck guard is folded down.
9. Traverse the cross slide and upper carriage by turning the
handwheels. Caution: Do not let the carriage or cutting tool
run against the lathe chuck!
10. When you have completed your work, use the master switch
to shut off the machine.
Example of face turning (b)
Note:
This operating method is used to face turn the face side of a
workpiece. To do so, proceed in the manner of the previously de-
scribed straight turning with the following particularities:
1. Clamp the right cutter adjusted by approx. 2° to 3°. The an-
gle adjustment must be set by swivelling the tool holder.
2. Move the cross slide with cutting tool from the outside to the
inside (towards the centre) while machining the right face or
shaft shoulders.
Caution!
For larger workpiece diameters, the cutting speed from the out-
side to the inside differs rather considerably. Therefore, infeed
the cutting tool with the cross slide slowly and with sensitivity!
Example of taper turning (c)
The upper carriage is equipped with a scale and can be swivelled
to two sides by 45° for taper turning. To do so, proceed as de-
scribed at "Working with the upper carriage". The method of ma-
chining is the same as for straight turning.
Parting a workpiece (d)
Caution!
Insert the parting tool as far as possible when clamping. Pay at-
tention to the exact height of the parting tool cutting edge! This
should be at the level of the rotary axis or just slightly below it!
1. Clamp the parting tool at right angles into the tool holder.
2. Move the cross slide with the cutting tool with sensitivity
from the outside to the inside (towards the centre). When it
passes the rotary axis of the workpiece, it is separated.
Caution:
Proceed with great caution here to prevent the separated work-
piece from flying around. Risk of injuries!
Machining longer workpieces with tailstock
and lathe centre (Fig. 12)
1. For this purpose, a centring hole must be drilled on the right
side of the workpiece.
2. Face turn the right face side as necessary.
3. Insert the drill chuck (accessory) in the quill 5 as described
in the chapter "Inserting the drill chuck" and clamp a centring
drill.
4. Release the clamping lever 2 and move the tailstock 6 with
drill chuck and centring drill close to the front face of the
workpiece. Retighten clamping lever 2.
5. Switch on the machine and drill the centring hole with the
help of the quill feed. To do so, turn the handwheel 3 to the
right on the tailstock and lightly push the centring drill in the
workpiece with the quill. Switch off the machine.
6. Move the quill 5 back with the handwheel 3 until the cone of
the drill chuck releases. Exchange the drill chuck for the trav-
elling lathe centre 1.
7. Move the travelling centre 1, or the tailstock 6 up to the work-
piece. Please note that the clamping lever 2 is clamped after
having been pushed up to the workpiece.
8. Infeed the quill with the handwheel 3 until all play is elimi-
nated.
9. Block the quill with the help of the knurled screw 4.
