2. DESCRIPTION OF THE MAIN UNITS
GEAR BOX
The gear box is mounted on the machine corp. the rotation motion to this gear
box is transferred through V-belts and belt pulley from an el. motor mounted on
the guide way.
QUADRANT
The quadrant is destinated to transfer the motion from the gear box to the feed
box through some change gears. It is mounted in the quadrant box. The latter
is closed by a cover.
FEED BOX
The feed box is fixed to the face side of the machine corp.—just below the gear
box. It includes all the mechanisms, by the help of which is effected the
adjustment for selection of the feed or thread pitches.
Required adjustments for the different values of the feed or thread pitch are
realized by the help of respective drums, located on the front part of the feed
box.
CARRIAGE GROUP AND ITS MECHANISMS
The carriage group is destinated for fixing and driving the cutting too. It
includes five basic parts: carriage box, carriage board, lower slide, cross piece
and upper (top) slide.
A. Carriage box
The carriage box is mounted on the carriage board. It contain the mechanisms
that are used for driving the carriage longitudinal and cross feed, as well as the
mechanism for engagement of the nut to the lead-screw while threading and
the mechanism for manual feed of the carriage.
B. Carriage board
The carriage board is mounted on the corp. guide ways. All the rest parts of the
carriage group are fixed to this carriage board.
C. The lower slide moved on the guide ways of the carriage board in

transverse direction. This movement may be effected automatically or
manually.
D. When short cones have to turned by hand, the cross piece may be
swiveled at 90° towards the lower slide in both directions and be fixed in the
required position by the help of suitable bolts and nuts.
E. The top slide on which the four-position tool holder is mounted, may be
shifted only by hand in the direction of the cross-piece.
Thus you may obtain longitudinal, cross and combined feed for the cutting tool.
THREAD-INDICATOR
This device is mounted to the carriage box (disengaged to the driving screw)
for getting into thread pitch
TAIL STOCK
The tailstock is clamped to the corp. guide ways. It is designed for working
piece clamping during machining between centers for drilling operations with
manual feed of the tool.

3. MACHINE INSTALLATION
TRANSPORTATION
The machine is transported in a special wooden case (or with foot stands
separately packed in carton), being fixed to the base of the case or slide by
suitable bolts. Some of the accessories are mounted on the lathe well fixed
and the other packed in a separate box or directly fixed on the case base.
The places where the ropes or chains have to be passed during handling of
the packed machine are marked on the packing. Be aware of the heavy side
while you are handling the machine with forklift.
UNPACKING
After the machine had been unpacked, check carefully its general condition, as
well as the availability and condition of all the accessories, shown in the
packing list.
HANDLING
Unpacked machine shall be handled only by the help of a suitable crane.
Before passing the ropes over the specified places, shown on the Fig.2, pull
out the tailstock and carriage and fix them in the rear hand position so that
when lifting the machine you will obtain required balancing. When handling the
machine never strike or hit it sharply because this may affect the machine
accuracy—irrespective of whether there are or not may visible defects.
Since the paint on some part of the machine may be damaged during handling,
place protective pads of fabrics or other suitable material on the respective
places.
PREPARATION
Before mounting the machine on the predetermined place, clean it carefully
from the protective oil. Respective machine surface shall be washed by the
help of pure naphtha or benzine.
This protective oil shall not be removed by hard objects or solvent that may
damage the metal surface or paint of the machine. Well-cleaned surfaces are
dried by the help of dry threads and covered with pure machine oil. Remove
the end gear cover. Clean all components of the end gear assembly and coat
all gears with heavy, non-slinging grease.
MOUNTING, FOUNDATIONS AND LEVELLING
To obtain accurate, durable and trouble-free operation of the machine, mount it
only on suitable, foundation and level it carefully. The foundation is prepared

OWNER’S MANUAL
Page - 13 -
by concrete with a thickness from 200 to 300 mm according to the soil
strengthness.
The unpacked machine is lifted by crane according to the specified method
and after the anchor and leveling bolts are in place, lower the foundation so
that the anchor bolts enter into the respective holes. The leveling plates (shims)
are placed below the leveling bolts. The guide way horizontality is checked in
longitudinal and transverse direction towards the machine axis by the help of
level with an accuracy of ±0.02/1000 mm and ± 0.04/1000 mm. After this initial
machine leveling had been carried out, pour the holes for the anchor bolts and
the space blew the machine legs with cement putty with ratio between the
cement and sand 1:3
After the cement is setted well (3-4days), tighten the nuts of the anchor bolts
carefully and evenly.
Check the machine leveling once again and if necessary—correct it by the help
of the leveling bolts.
CONNECTION TO THE EL. SUPPLY SOURCE
Check whether the data on the el. panel scheme (voltage and frequency of the
supply source) correspond to the available.
The controlling level should remain in the middle and also press down the
switch to keep the machine power off.
Make sure the lathe in properly grounded.
PUTTING INTO OPERATION
Before starting the machine, clean it once again carefully and lubricate it
according to the Fig. 3a 3b 3c –Lubrication System.
Check the V-Type belt, which located from motor to the low speed wheels,
whether it’s too tight or not. Too tight belt will spoil the bearings, also, if the
V-Type belt is too lengthened, it will skid, so the belt must be adjusted
Starting is effected in the following order:
Check manually the movement of all mechanisms. It shall be smooth. Check
also the operation of all the controls.
Fill the tank of the cooling system with the specified coolant (optional
accessory to be ordered separated). Switch on the main el. motor.

OWNER’S MANUAL

4. MACHINE SERVICE
LUBRICATION
The trouble-free operation on the lathe depends on its careful servicing. Of
special importance is the regular lubrication of all machine-operating parts with
the recommended lubricants. These lubricants are listed in the Fig. 3a 3b 3c
–Lubricating System.
The headstock (see Fig. 3a 3b 3c) is lubricated by the splash in of the oil,
charged in it. The oil may be poured into after removal of the cap from the
combined oil vent with oil filler. (p.1), located in the headstock cover. The oil
draining by unscrewing the plug (p.1--1) to the oil draining tube. If the oil has to
be replaced, clean the headstock with pure naphtha carefully. While charging
new, its level must be to the middle of the oil sight glass. The disk couplers and
the main spindle front bearing are lubricated by an oil-collecting groove.
The feed box is charged oil through a hole (p.2), located in its l. h. side (III type
feed box) and r. h. side (I & II type feed box) (viewed frontally). The oil quantity
must be also such that its level reaches the middle of the sight glass. The oil
drainage is effected through the plug (p.2--2).
The change gear sleeve for the quadrant shall be lubricated with grease once
per day by the help of suitable oiler. The change gears shall be lubricated with
oil once per shift.
The carriage box is lubricated through a common hole (p.3), wherefrom the oil
is fed into a tank which is also common for the whole box. By suitable grooves
the oil is fed further to the respective bearing as a portion of it drops on the
bottom of the box, from where the gears are oiled. The oil is drained through a
plug (p.3--3).
The carriage as well as the slide-guiding surface are lubricated by the help of
suitable oilers (p.6), pressed into the carriage and cross slider (p.8). The el.
motor bearing shall be cleaned well and filled with new grease once per six
months. All the friction surfaces of the carriage, traveling stock and conic lineal
shall be oiled by the help of an oil-holder or oiler according to the lubricating
system. The lubricating points are marked in the Fig. 3a 3b 3c –Lubrication
System.
