It is incorporated with slide gear structure. Turn off the power and loose screws inside the
exchange gear cover and screws in the exchange gear cover. Push or pull the slide gear to the
position shown in Table 1-5 by hand (the empty revolution of the gear is less 0.1mm). Fixed the
above loosen screws and try to turn the exchange gears and see it run flexibly, and four kinds of
threads about metric, inch system, module and diametric pitch can be transformed each other.
5.2.3 Feed box
Feed box is consisted of basic thread pitch changeover mechanism, multiplying mechanism
and metric, inch thread changeover mechanism.
Basic thread pitch changeover mechanism is operated through lever 21, so do multiplying
mechanism through 22, and metric, inch thread changeover through lever 23.
The thread was listed in table 1-5, cutting feed volume was listed in table 1-6.
5.2.4 Carriage
It consists of thread cutting mechanism, longitudinal, transverse manual and automatic
operation system, and rapid moving system. The machine type of 950mm and 1450mm with
rapid motor is supplied by order. The position of levers shown in Fig.1-9 and its relationship in
the nameplates of the carriage.
a) Thread cutting: lift up the lever20 to the open position; lever14 in the middle neutral
position, then operate the lever11.
b) Longitudinal, transverse manual feeding: lever11, 20 up to open position, lever14 in the
middle neutral position, operate the lever8 to perform the longitudinal feeding and lever9
for transverse feeding.
c) Longitudinal, transverse automatic feeding: if handle wheel8, 9 with folding knob, must
fold the knob in the wheel before rapid feeding or automatic feeding. First lever11 up to
open position; then to choose longitudinal or transverse feeding by lever14, finally use
lever20 to get automatic feeding.
d) Rapid moving system: rapid movement can complete by rapid motor to directly drive the
carriage in longitudinal and cross slide in transverse direction.
First lift lever11、20 to open position, then choose longitudinal or traverse feeding by
lever14, finally push button12 to get the rapid moving.
5.2.5 Footbrake mechanism and electric braking device
Action of footbrake mechanism is the same as that of electric braking device． User can
choose one in respond to the requirement.
While the footbrake mechanism cut off power by footboard 19 through lever mechanism,
the braking belt tightens the wheel on the axis of motor, consequently the lathe stop quickly.
5.2.6 lubrication systems
The lathe should be lubricated and cleaned fully to keep it high accuracy and long enough life.
All cups on the lead screw clutch, slide and tailstock can be lubricated by oil gun. The high
melting grease should be added to the bearing on lubricating position of the exchange gear every
50 hours (type of recommendation: ZL-4/SY1412-75).．The lead screw should be cleaned, and
injected oil with oil gun before cutting thread, So do smooth rod and slide guide. The guide can
also be lubricated by pump on the carriage.

6 Operation and precautionary measures
6.1Operation
Starting and the operation procedure in processing, stop procedure, the operating methods
and attention shown in the (Electrical Part) of the <operation manual>
The diagram of operation position was shown in Fig.1-9, the description of action was listed
in table 1-9.
6.2 Precautionary measures
a) Before starting the lathe, read the OPERATION MANUAL carefully, clean and lubricate
it fully as specified.
b) Operated rod 18 should be placed on the middle position before the main switch1 being
connected. The emergency button 6 and quick feeding button 12 should be opened
c) To change main spindle speed should be done after the lathe stopped, it’s forbidden to
shift the speed change lever in spindle running. Feed change, lead and smooth rod choice
should be operated at low speed or after the lathe stopped. Point movable button5 can be
used to make the operation become easy.
d) As the lathe was equipped with brake or treadle braking apparatus, don’t break it by
reversing.
e) Brake braking frequency ≤5 times /min.
f) Face plate velocity ≤the number marked on head stock.. It is forbidden to use the face
-plate and chuck whose diameter is larger than stipulated in the packing list. When the
chuck run at high speed, its jaws must hold the work-piece to avoid the jaws may fly out
from the chuck.
g) Cutting feed was listed in table 1-10 at high speed.

7 Maintenance, conservation and adjustment
7.1 Daily conservation
a) Before doing work every day, lubricate the machine fully to ensure it can be started
under normal condition.
b) After finishing work every day, sweep up and remove cutting washer and clean all part of
the machine, daub rust protection oil on it.
c) Take care of centers, axle neck of main spindle which fixed chuck and guide-way to keep
the lathe have a high processing accuracy.
d) Lubrication oil should be often injected between slide block and work-piece when steady
rest and follow rest being used. To ensure satisfied accuracy, adjust the slide block and
work-piece at any time as required.
e) To prolong the working life of lead screw and half-nut, use the half-nut only in screw
cutting (lubricate the half-nut before use).
f) Something happen while the lathe work, stop to examine it.

7.4 Adjustment
7.4.1 Pre-fastening and replace of the V-belt
General inspection should be made so as to keep the v-belt with some pre-fastening tension.
Otherwise, it will be worn out quickly. Therefore, check it regularly. The method is: press down
the v-belt about 5 mm by thumb appropriately. Otherwise it needs to adjust.
Adjust the V-belt regularly according to the following procedures: 1) pull the belt in the
vertical direction of the wheel and the force must be in the middle of the two wheels.2) fix the
four mounting bolts on the pedal of the motor. 3) Turn the adjust bolts and move the pedal of the
motor to let the V-belt have proper degree of tightness. First adjustment is done after 3 months of
the machine installed, afterwards, adjust every 6 months.
When the V-belt is required to be replaced, so do a couple of V-belt with same size and
specification.

7.4.2 Adjustment of the Headstock
If the cylinder gauge doesn’t conform to that of the certificate (item b p1), examine the
parallelism between center’s line of headstock and the guide-way, and adjust it as follows:
As shown in Fig.1-10, unfasten 4 bolts on the headstock, adjust two hexagon head bolts on
the part (1), revolve the headstock on the horizontal position, and adjust its center’s line. After
adjustment, refasten all bolts and nuts, examine again to be sure it is pretty good. (refer to item
G7 of the < test certificate>.

7.4.3 Adjustment of main spindle bearings
If the main spindle bearings gap is too big, it will influence the processing precision
directly. There are two kinds of spindle accuracy that is radial run-out (item G5) and axial slip
(item G6) which are guaranteed by front and hind bearings, and usually adjusted to be ready for
use before leaving the manufacturer. If the spindle must be adjusted because of being knocked by
tool rest or other reasons, please adjust the front and hind bearings of main spindle
simultaneously and also separately as requirement. The method was shown in Fig.1-11, The front
bearing adjustment: unfasten screw 3, adjust nut 4 as required then refasten the screw 3.The hind
bearing adjustment: unfasten nut 1, adjust nut 2 as you need, and refasten nut 1.After adjusting
the major bearings, let the machine run around 1 hour without loading, then examine its
temperature increment. General temperature rise are 25℃-40℃. The temperature contrast
between the front and hind bearings is usually less than 10℃. The temperature of spindle
bearings is not allowed to exceed 70℃, otherwise, loosen the nut slightly.
