Cross lathe-turning
Cross lathe-turning is carried out in a similar way to the
longitudinal one. A tool is moving towards the workpiece
centre when cross turning.
Set the main blade precisely over the workpiece
centre so there is no residue on a workpiece. Set the
tool along with centre point (2/19).
Inner lathe-turning
Inner lathe-turning is carried out in a similar way to the
cross and longitudinal turning. Because the tool is not
visible most of the time while turning, one must proceed
very carefully here.
Neck down and gauge out
Necking tool is used for necking down and scooper for
gauging out.
Taper turning
Loose the setscrews
Rotate the top slides (2/7) about its axis
Set the scale division
Tighten up the setscrews after the top slides were set
properly
Thread turning
Use special threading tool for thread turning, which is
to be fastened exactly perpendicularly towards the
workpiece axis.
When thread turning, the feed is done by leading
spindle (2/13) and must correspond with thread pitch.
Corresponding feeding speed is set by right
combination of the gearwheels (see Feed
adjustment).
Operation (pict. 2)
Turning the machine ON and OFF
The revolution controller (2/1) must be switched to
zero position before every the start or change of
turning direction.
Now set the right direction on selecting switch for
revolution direction (2/2). (L= left run / R= right run).
To turn on, press the revolution controller (2/1).
To turn off, press the main switch (2/3).

Instructions step by step (pict. 2)
Fasten the tool firmly in the tool holder.
Fasten the workpiece tightly and as far as possible in
3-jaw chuck (2/23).
Check if the workpiece is running without wobbling.
Feed must be always deactivated but not at thread
turning.
Turn the machine on.
Transport and storage
During the transport, the longitudinal slides must be shifted
forward the end of the support close to the tailstock and
fastened there.
Maintenance and treatment
Plug the power cord out of the socket before
every maintenance and cleaning!
You must pay attention to general maintenance when
using the machine. This will ensure high accuracy and
reliability of the operation for very long time.
1.
Remove the metal chips with brush.
2.
Before the start and after the finish of the work it is
necessary to lubricate all moving parts.
3.
Remove the metal chips from the sliding and
conducting surfaces regularly and lubricate again
especially when working with cast iron, brass, bronze
and aluminum. Do not blow the surfaces with
compressed air. Use broom, brush or vacuum cleaner
for cleaning.
4.
Check if metal abrasion residue is not deposited on
felt wipers between conducting surfaces. Remove a
metal abrasion, clean out felt wipers and fasten them
back so they will bear against conducting surfaces.
Grease the felt and conducting surfaces.
5.
To ensure high accuracy of the machine, the centre
punch points, conducting surfaces, sliding spindles,
etc. must be treated carefully.
If you find out any damages when checking the
machine, repair it immediately.
