2. DESCRIPTION OF ELECTRICAL EQUIPMENT OPERATION
2.1. PRINCIPAL ELECTRIC DIAGRAM OF MAIN DRIVE AND CROSS-RAIL CONTROL (fig.2)
The electric diagram provides for the following operations:
start and stop of the main drive electric motor and lubrication system electric
motor. Reverse motion of the main drive electric motor;
cross-rail up and down.
2.1.1. Main drive electric motor control
Main drive electric motor control is carried out from the push-button pendant
station by buttons 1KH2 ("Start") and 1KH1 ("Stop").
Zhen depressing the button 1л H 2 ("Start") the starter 1K1 of main drive electric
motor is switched on. The limiting smooth idling relay 1P1 of the main drive electric
motor is switched on. The relay operates with time! If the table does not set
in motion during that time, then circuit opening contact of time relay (circuit 4) will
' ' /
switch off the main drive starter.
Main drive electric motor is switched, off by button 1K Н1 ("Stop").If the table
rotates, the button 1Kii1 is blocked oy circuit closing contact of step-by-step
. elector llEIT . The faceplate has been stopped and step-by-step selector is in zero
position, the main drive motor may* be switched off.
2.1.2. Cross-rail centre..
The cross-rail traverse i: controlled by depressing the button 1E Hj ("Up") or 1K H4
("Down").
Preliminary the cross-rail is unclamped by handle, in so doing the contact of limit
switch 1BK1 (circuit • ' li> closed.
Button 1K HJ being pusped the magnetic starter 1K2 (circuit 6) of cross-rail tra-
versing motor is switched on.The cross-rail is moved upward till the button 1K И? is
depressed or until the jirnit switch 1B&2 will operate. Cross-rail downward traverse dif-
fers from cross-rail upward traverse. Button 1K i’ft being released or limit switch 1BKJ
(if limiting of owpwaii traverse) being operated, magnetic starter 1K2 has been
switched through contact of time-relay 11*2 of choice of clearance (circuit 5) prior to
cross-rail clamping. The magnetic starter- switches on the electric motor of cross-rail
X

2.2. PRINCIPAL ELECTRIC DIAGRAM 0? TABLE CONTROL5)
2.2.1. Choics of faceplate rotation speed.
Adjustment of faceplate rotation speed on the machine is a stepped one, .It is
carried out by means of speed box with electromagnetic couplings, which provide di-
rect switching over from one speed to another, whilst the faceplate is in motion.
The faceplate has 18 ranges of speed, which are selected and set by means of
sliding contact switch 134, mounted on the control pendant station.
The actuator, which directly switches on and over the relays of composition of
faceplate speeds diagram (1?5>•-1P1O; 1P14, 1218, 1219) is a reverse step-by-step
selector ШИ . The selector has the following coils: ШуМ (decreasing of faceplate
rotation frequency), ШИ-Б (increasing of faceplate rotation frequency). Table being
motionless step-by-step selector is always in initial "zero” position, which conforms
to switch on increasing (1P11) and decreasing (1P12) relays of faceplate rotation
speed. In so doing ell relays of composition of faceplate speeds diagram are deener-
gized, and through combinations of their Circuit opening contacts the diagram of face-
plate braking is composed and switched on (I3!’8,I3y9 )•
When main drive being switched on, operating voltage 24V of 1X3 is supplied through
contact of its starter 1K1 (circuit 34) to control circuit of relay 1213 of faceplate
start. The step-by-step selector is in' tile initial position due to the energized relays
1211; 1P72. Relays 1211, 1212 are switched on in circuit И 14-85-86-109-138-139-137-
914, the first one - due to half perioc of working voltage from 914 to И 14 , the
second v.v. - from И 14 to ';14. (Tapperative half-periods of voltage for given relays
ore released by parallel diodes\£Il and 1ДТ2 ).
Suppose we have chosen l:.cepi <re\speed that is propel’ for the 12-th position of
switch 1B4. Sutton 1Kiu3 ("Faceplate start") being pushed relay 1P13 is energized and
by its contacts is circuit^ 39 and Ы disconnects the feeding circuit of field Щ'-S
from feeding source-.of 5l7 (И14 ) and connects it to switch 134 slider. Due to diode
circuit (1Д23-1Д31» )» which is connected in series to circuit of relays 1211 and 1212,
the relay 1212 is uisconnected, because working voltage of its coil will be closed by
diode circuit. Vhen being,deenergized the relay 1212 by its circuit closing contacts
in circuit 6? and 3$'4-switches on coil ШИ-Б and relay 1221 of speed diagram switch-
ing over, '’the relay 1221 by its circuit opening contact in circuit 39 opens the
feeding circuits "of relays of speed diagram composition. Coil ШИ-Б attracts the electro.
/. У -
magnet armature and at the same time by its circuit opening contact in circuit 54
deenergizes relay 1211. The latter by its contact in circuit 68 deexcites the coil,
then electromagnet armature being dropped, step-by-step selector makes one step
and shifts the brushes in position "1". In so doing relays 1P11, 1212 are engaged
along circuit И 14-170-124-86-109-133-139-157-914, and by their opening contacts in
7
circuits 37 disengage relay 1P21. The latter with delay of time engages the feeding
circuits of relay of speed diagram composition. Belays 1P6, 1P8, 1P14, 1P19 are
engaged and by their closing contacts in circuits 43,45, 48, 51 engage the clutches
of the 1-st speed 1Эм2, 1Эм4, 1Эм7, 1ЭМ9, I3mI0. Belay 1P19 in circuit 49 by its
opening contact disengages clutch1Эм8 the faceplate starts to spqed up at the 1-st
speed, Step-by-step selector being in "1" position, relay 1R20 feeding circuit is
disengaged.Relay P2O with delay of time (2-2,5 sec.) by its closing contact in circuit
65 disengages the feeding circuit of ruiayh 1P11, 1x12. Thus relay is disengaged, and
relay 1P11 is engaged due to diode circuit 1Д24.. .1ДЗ4.Coil ‘ШИ-Б& engaged and
attracts the electromagnetic armature, by its opening contact in circuit 64 dis-
engages relay 1P11. Relay 1P11 disengages coil ljH-o,the latter releases the electromag-
net armature. Thus relay 1P11 and coil ШИ-Б start operation in regime of multivibra-
tor. In armature dropping step-by-step selector will shift the brushes for one step
in the direction of increasing of faceplate rotation frequency. Nevei^helees, it is
to be noted that step-by-step selector motion is carried out when the 1-st speed
clutches are engaged, because the diagram will be blocked by circuit closing contact
of relays 126, 1P8, 1214, 1P19.
When step-by-step selector reaches the i‘-th position, relays 1P11, 1212 are
energized and relay 1P21 is deenergized. Diagram of the 11-th speed will be composed
and thus step-by-step selector is not shifted in the course of time lag of relay 1P20
(2-2,5 sec.-), then the faceplate is speeding-up at the 11-th speed.
Timo lags of relay 1P20 on the 1, 11, 14, 1?-th steps of speeding-up are chosen
with allowance for optimum faceplate speeding-up and are determined by condenser
1C1O. Time lag of relay 1P20 on the 114th step being over, relay 1P12 is deenergized
and ШК-Б is switched on, step-by-step selector will be shifted in position 12. In so
doing brushes kM position coinsides with that of switch 1B4 slide. As a result
relay 1P12 is energized and relay 1P21 is deenergized, so the diagram of the 12-th
speed will be composed, and the clutches of speed box will be engaged according to
the 12-th faceplate speed'» The faceplate will be speeded-up and will operate at the
12-th speed.
When sliding contact switch 1B4 is switched over from the 11-th to the 18-th posi-
tion, step-by-step selector will be shifted until brushes position coinsides with that
of slide 1B4. Step-by-step selector will stop in positions 14 and 17 on time lag of
relay 1220 { the diagram of the 14-th and 17-th speeds will be composed.The faceplate
will be speeded-up at these speeds. When step-by-step selector reaches position ”18",
8
the position of its brushes will coinside with that of slide 1B4 and the diagram of
the 18-th speed will be composed. It is to be noted, that clutches operating diagmm,
when switching over the previous diagram to a new one, remains switched on dur-ing
diagram switching over, that is achieved by means of blocking of relays II^-IPIO, 1P14,
1P1B, 1P19 being switched on through circuit closing contacts of relays of 1P5-1P1O,
1P14, 1P18, 1P19. / '
If smaller speed (for example, the 4-th one) ie set by switch 134, then the relay
1P11 and coil Л'-М start operation in regime of multivibrator shifting brushes ШИ in
side of their coincidence with position of slide 1B4. On the 17, 14, 11-th steps the
table slowing down takes place on time lag of relay 1P2O. when step-by-step selector
reaches position "4", it stops; the speed diagram of the 4-th position will be com-
posed and the faceplate will rotate at that speed. In shifting of step-by-step selector
when only one of multivibrators 1P11 ЩИ-ul or 1У1: ИМ-Б operates, the circuit of relay
1P21 coil is opened with each Ш step, nevertheless/the relay is energized due to
condenser 1C11. 1P21 is deenergized only when ШИ position has coordinated with that
of switch 1B4 slide. In such a way, if anjAcharige of speed, step-by-step selector is
shifted in side of coincidence of brushes position with that of slide.Speeding-up
(braking) steps are chosen in sucli a way that to get optimum operating conditions of
speed box, when speed is changed.
n order to prevent impacts in speed box when switching over from step to step,the
scheme provides clutches 13m1...13m 1G engagement on time-lag. The clutches of pre-
vious step having been switched on and being switched on, the next step are not switch-
ed over due to blocking of the relay diagram. The clutches which do not take part in
the next step, are switched off. Heswitchfed clutches are switched on with time lag
due to relay 1P21 - (1,5-2 sec.).
The faceplate is deenergized, by depressing button 1Kji 6. in this case the brush 1B4
is deenergized, and voltBge is supplied to field ШИ-8 "0" through 1P1J circuit орегилк
contact in circuit p'-j/ In so doing ШИ returns to initial zero position, as a resulЪ_ДГ
faceplate braking clutches'are engaged, the faceplate is stopped.
2.2.2. Faceplate jogging /
For jogging, switch 132 is set in position 2 "Jog" relays 1P6; 1P14 are engaged.
Button 1KH.5 ("Start") being pushed relays 1P8, 1P19 are engaged, the diagram of the
first faceplate speed is composed, jogging operating mode takes place at that speed.
Button IKE,5 being released, relays 1P8, 1P19 are deenergized. Diagram of faceplate
braking is recomposed, and the faceplate in stopped
<.<•>. Faceplate operation when constant cutting speed..
Constant cutting speed device (V^.^xconst,) provides for upper head and 'it can be
used for face turning with head motion to and from the faceplate centre. For faceplate
to operate in that mode it is necessary to chose initial faceplate speed by means of
switch 2&i and start the faceplate pushing button 1Kh 5 "Start". After that set switch
IB? in position Vsconstant. •’he circuit for relay 1P16 engagement (circuit >8) is
created. When working feed direction has been chosen by switch 2132 it is necessary to
switch on th. working feed by depressing button 2KH2. If feed "frota centre', is chosen,
relay 1Р2Э will be energized, (if "to centre",then tne relay 122> will not be energized).
Relay 1P16 is energized whatever the head motion direction through circuit opening
contact ii'l'l (circuit >8),which is closed when faceplate being speeded up • > the
-nitial rotation frequency.

1P11 and 1112 are deenergized, relay 122'1 is deenergized and by its circuit opening
contacts in circuit 3<-switches on a new relay diagram. The' relays, in turn, engage
proper clutches of the new faceplate speed, which is one step more (or less) the pre-
vious one,-. Becan::-: is pushed relays 1i'i1 and-1212 .are switched on and coils

tion. Th- limit ./witch 13X6 being pushed,the step-by-step Selector is shifted for
one step in side of increasing (or decreasing) of faceplate rotation speed.If step-by-
10
step selector reaches the position of mismatch (terminals 37 or IO*) if is stopped
and further cutting will be carried out at constant rotation frequency. On head dis-
connection the faceplate rotation speed is preserved, because relay' 1P16 is switched
on. Only after switch 1B3 has been set in position V / const, the faceplate picks up
initial rotation frequency.
2.3. PRINCIPAL LLLCTRICAL CONTROL DIAGRAM OF HEAD (flg.4)
*
2.5.1. Head control.
Head control diagram provides the following operating duties:
choice of mot.bn direction (to centre,from centre, up, down);
brake on and off;
choice of feed value; /
/
Z-orking feeds switching on;
set traverses switching on.
'hoic-..- of lirection of head notion is .carried o.i by cross switch B2. If we have
c:.ocon hori.- .'ntal head motion, then..indepe’nd nitly of tumbler BJ position (brake "On")
with head switched on, braking clutches of\hr-ad horizontal traverse are disengaged
and braking clutched of head vertical tra”- can be engaged by tumbler BJ.Alter-
natively, if we have chosen head vertical traverses, then braking clutches of head
vertical traverse are switcher, off inde/endantiy of tumbler B3 position, and braking
clutches of head horizontal feeds can be engaged and disengaged by tumbler 35.
Head being : topped, brak.rig clutches of horizontal and vertical traverses are
engaged or disengaged by tumble'r BJ. .
Head {?•••! value is chosen by -i idinr contact switch 31, which has 18 positions
depending'on feed value. Working; feeds are switched on by depressing the master button
KF< _’£ cross switch B2. tentatively it is necessary to switch on the faceplate, set
feed switch in position 2 ("Working feed"), choose the value ind direction of feed.
Sutton KHR being depressed relay 22 and clutch of chosen feed direction are engaged.
Relay P2 by its contacts in circuits 79» 31, 85, 87 places on blocking itself and the
clutch being engaged. Relay P2 engages working- clutch Эм 7 .and braking relay P3 and
opens the circuits Of. braking clutches. Relay P3 by its contacts in circuits 81 and 83
prepare- the circuits of braking clutches when head is switched of. The head is
stopped if crosh—switch handle is turned in neutral position. In this case directional
clutch Ind relay ?2.are disengaged. Relay P2 by its contact in circuit 3? deenergizes
working clutch ,Эм 7 and braking relay P}, and in circuits 81 and 83 engages the head
braking clutches Эм 3, Эм H-. TilEe of braking being over (time lag of relay P3=1,5 -
2 sec.),braking clutches are disengaged by circuit closing contact of relay ?3.
II
2.3.2. Set traverses switching on.
Head set traverses are effected by electric motor M1. For this purpose switch B4-,
mounted on control station should be set in position 1. Working clutch Эм 7 circuit
87 is opened and circuit 70 of electric motor starter K1 switching on is prepared.
Proper head motion is chosen by cross-switch B2. Relay P2 and directional clutch are
engaged by button Кц 2. Relay 22 in circuit 70 switches on starter K1, which is
placed on blocking in circuit 71. Relay P2 by its contacts in circuits 81, 33 and 87
opens the braking clutches circuits and engages braking relay 23. Starter K1 by its
power contacts in circuit 73 switches on electric motor M1, and by block-contacts in
circuit 79 opens the blocking circuit of feed to be switched on. Relay 23 by its con-
tacts in circuit 70 opens the circuit of starter K1 switching on, and in circuit 71
connects in parallel the relay 22 circuit closing contact of head switching on. Button
/ /
Kh2 being released the relay 22 and directional clutch are deenergized. Due to relay
23 time lag braking clutches ЭмЗ and3»4 are engaged in, circuits 81 and 83. On time
\ / ,
of braking starter K1 is blocked in circuit 71, the mdtor remains switched on. All is
done for limiting the frequency of electrical motor Ml starts.
2.3.3. Head lubrication
Lubricators with electromechanical drive are mounted for head lubrication. The
lubrication is carried out when head sei traverses with the help of closing contact by
means of starter K1 in circuit ?4.
2.4. PRINCIPAL 3EECTRI0 DIAGRAM OF TURRET HEAD TURNING AND CLAMPING (fig.2)
The turret head hrn. - fi^ed positions. To turn the turret head from one position
to the otncr it is-necessary to depress button 2КнЗ» The button 2Kh3 energizes mag-
netic starter 2K1 - of • .флЪ clamping and turning. The magnetic starter by its circuit
closing Contacts in’circuit 94 engages the electric motor of turret drive - 2M4, and
in circuit 96 set;s on blocking through circuit opening contact of microswitch 2BK12
of turret head fixing ..and -in circuit 99 switches on relay 2P5. Thus, the turret head
is unclamped. At the end Of unclamping (before turning) limit Switch 2BK13 is released
and by its contact in circuit 101 deenergizes electromagnetic clutch 2Эм22. The turret
is turned td'necessary position (if the button is pressed). The turret being turned
microswitch 2BK12 operates. The latter deenergizes starter 2K2 (button 2Kh 3 should
be released) and switches on starter 2K3. The starter energizes electric motor 2M4 but
in reverse direction' - on turret head clamping. At the beginning of clamping process
limii switch 2BX13 operates and in circuit 101 energizes electromagnetic clutch 20м 22.
In the process of clamping limit switch 2BK12 is released, but the circuit of starter
2K3 is blocked preliminary by circuit opening contact of relay 22M1 (circuit 98). At
12
the end of clamping process limit switch 2BK11 of clamping control operates end by
its closing contact in circuit 77 (see fig.4) permits the head switching on. The ne-
cessary turret head clamoing force being achieved, the relay 2PH1 operates and starter
2K? and electric motor 2M4 are deenergized.
Note: Relay 2PM1 when J8OV, 40CV, 415V, 440V is adjusted for 2,5... 3,5A, when
220V - for 4,0... 5,2A.

b) to switch on the input circuit breaker 1BA1 and automat of control circuit 1ВАП ;
c) on the pendant station depress the buttonlKuli "Start" of the main drive. In so
doing, the shaft of electric motor rotor should rotate couterclockwise (look
from pulley side). If the direction of rotation does not coinside with the above
mentioned, it is necessary to switch over two any phases of the main lead-in.

Check the operation of oil pump and lubrication system electric motors, for this
it is necessary:
a) to energize the circuit breaker 13A2 of protection of oil pump electric motor;
b) to press button IKh2 on the pendant control station, cigrial lamp UIC' "Lubrica-
tion absent" should become dis; f J /
c) to switch on vertical head set traverses on the pendant station by means of
switch 32 and button Kh2 • In so doing the electric motor of lubrication system
should be switched on. Drive gears should rotate clockwise (look from side of
lubricators). ; - /
After that, check the operation of cross-rail Irive, limit switches 1BK2, 1BKJ
(limiting the cross-rail traverse) and limit switch 1BK1 of cross-rail clamping. For
this it is necessary to switch on circuit breaker 1BAJ, release the cross-rail with
the handle and depress one of the buttons ( уКнЗ or 1Kh4 ) of start of the electric mo-
tor of cross-rail traverse. Limit switch 1BK2’be/ng depressed manually (the cross-rail
traverses upward), the cross-rail should be stop; • i.^imilaxy, when cross-rail moves
downward and limit switch 1BK> being depressed the cross rail should stop. The cross-
rail being clamped (1БК1 is depressed) the lectric motor of traverse should not be
switched on.
After that it is necessary to check the limitation of head traverse. For this on
push-button pendant set the feed switch 2B‘+ and 4B4 in position "mm/min" and choose
156 mm/min feed by feed selector and with the help of cross-switch check alternatively
the direction of heads traverse. Sher, checking the proper head direction it is necessa-
ry to press manually the pusher of limit switch of head given traverse. The head
should stop. Choosing alternatively oy cross-switch the other directions for each head,
limit manually the head traverse. After that check the limitation of head traverses by
stops, if stop device tfi mounted on the machine,
\ /
Check the scheme of table control without main drive electric motor switching on.
For this purpose energize manually relay 1P15 of table start. Step-by-step selector
/
should be moved for one step, if speed selector is set in the 1-st position. On the
pendant, switch on alternatively each speed of the faceplate, otep-by-step selector
should folio* the switch. Relay 1P1J being released, step-by-step selector should be
returned to. initial zero position. Pay attention to delay time of speeding up (braking)
when past.rig through the 1-st, 11, 1* and 17-th steps of speed.
