Shtprme7'! amd Trcmsc't. Before shipment from the Factory) this machine was given
a fun-load running test for several hours at au speeds and feeds) and every machine
element was in correct adjustment and alignment at the conclusion of the test) at which
time all oil was drawn from lubrication reservoirs.
When placed on the car, the machine was properly skidded and blocked, and all
bright parts heavily coated with slushing compound, and the entire machin-e enveloped in
a waterproof cover intended to protect it from the elements as well as from cinders arid dirt.
While in transit the machine has been subjected to conditions beyond our control;
the covering may have been removed or torn) thus allowing cinders and dirt to.lodge in
and around the machine; or the car may have been roughly handled in switching) and if so,
the machine may have been subjected to injurious jolts and strains which may affect its
alignment and operation.
RECEIVING YOUR MACHINE AND UNLOADING FROM CAR

LUBRICATION
The hfe and good service of a machine tool depends upon its proper lubrication, and
special attention has been given to this important fuhction in the design of the cut Master
Vertical Turret Lathes.
I
Table spindle bearings, spindle gear and pinion, headstock clutch and-,brake) gear
shift mechanism) and all brackets on the top of the machine with the exception of the
rail raising brackets are lubricated by means of a constant speed) positive displacement
pump located in the bottom of the clutch case bracket. The oil is drawn from--the base
of the machine through a filter, and is then pumped under pressure to the poirits ndentioned
above from which it returns by gravity to the base.
A pressure gauge and switch are mounted on the rLcrht-hand side of the bed connected
in the main high pressure s3rvice line insuring constantlv maintained oil presstire. If an
abnormal drop in pressure occurs) the main power units ;ease to function.
The feed brackets, rail raising brackets) and the gear trains within 'the various heads
are lubricated independentlv from their own reservoirs in which the oil level must be
maintained.
All slide bearings and feed screws are arranged for independent pump gun I.ubrication.

LUBRICANT SPECIFICATIONS
Continuous, long-te-) trouble-free operation of modern Machine Tools can only be
achieved if proper lubrication controls are estabtished and maintained.
Fundamentafly) successful control must include :
(A)
Careful and wise purchasing of the most suitable lubricating and hydraulic
oils to specifications.
(B)
(C)
Cleanliness in installation and application of lubricants.
A simple but positive test at regular periods to deterlnine COnditiOnS Of Oils.

Neutralization Number is the
index of acidity of oils.
It is obtained by i.ollowing the procedures set forth in A.S.T.M.
.. Spec. D663 or D664 of the _American Society for Testing Materials. Durintjcr use of machimes) organic acids are I'ormed in the lubricating oils.
lhThen an oil has become con-
taminated with organic acids to the point where its Neutralization Number equals or
exceeds (0.5), oxidation can increase at a very rapid rate) resulting in attack on the machine
members and causing their malfunctioning. Badly contaminated machines require very
frequent oil changes to thorou_a.hly clean their systems.
The use of the Neutralization test) plus an exami-tion of the ch'#ere7?Ce in appearance
and odor of new and used oils, will tell a user when to change oils. Complete tests should
:; be made if a slight rancid odor is noted at any time. Copies of testmethodsmaybe obtained
I'rom the American Society for Testing Materials, 1916 Race Street', Philadelphia 3) Pennsylvania. Test can be performed bv the user if simple facilities are available or by any
commercial laboratory at a nominal.charge.

SUGGESTED I:UBRICATION MAINTENANCE SYSTEM
The Bullard plant has practiced the following hit,a.hly successful lubrication control
system for the past five years. It has been applied to all types of -\Iachin6 Tools which
have been produced by over thirty different -\Iachine Tool Builders and has proven to be
economical in every respect..
1.
_ill lubricants are bought to specification and laborator]. acceptance tests are made.
Instr2riclil.nnd1:V:d.uk:1acnadrdl:stairneg mmaeea.odut.ffo.:1ienag:ht,I,np:a;hinleuTr:cs:nng, i:do¥hteiro:ufbrroiFa,:nh:
information.
3.
Laboratory test; are made on samples from main reservoirs for ,important oil
characteristics.
i
Laboratory reports are used as a basis for determining sampling and change
periods.
5.
h-ew machines have oil chang.ed after one month of operation.
6. Initially, a check period of every foul. months is employed) but the final check
period will be determined by experience.
7. We Cha,nge Otl When the Nentralizckon N"mbe1. ReaiI..es 0.5 (Mithgrorms of KOH
per Gra,m of Oil) Regard1,ess of lay Other Consideraiton_
8. When changing oil, we clean all filters and lnOP Out Sumps tO remove any accumulated sludge and dirt.
9.
tl
We lubricate T\_ays and Feed LScrews (Zerk Fittings) once each shift. I-
10. Small reservoirs, under 5 gals. capacity, containing heavy oil, can be changed
more cheaply than the a.ost of tests to determine the condition of the oil. We change
them,every six months as a routine proposition.
I
i
\
TO START MACHINE
1. Start the main drive motor by pressing the start-button located at the right-hand
side of the machine. The start-button must be held in t,he depressed position for a few
seconds to allow the oil lubrication pump to build up a sufficient pressure to operate a
pressure switch which in turn holds the circuit for the main drive motor.
2. Move the Clutch Brake switch lever on the Pendant type control to the Brake
position which releases the mechanical interlock holding the speed selector dial.
3.
Set the speed dial to the slowest spindle speed.
4. Move the Glut.ch Brake lever on the Pendant to the Clutch position.
5. To start the spindle in motion; the machine is equipped with conveniently located
start and stop switches) one for each head on the machine, which are wired in series with
the Pendant. With this arrangement the spindle will not start until one of these Start
switches fL1.e energized.
The spindle may be stopped by either energizing one of the Stop buttons or by
switching the Clutch Brake switch on the Pendant to the Brake position.
There are many cases which require jogging of the table for positioning and indicating
purposes. This is very easily accomplished through the use of the Start-Stop switches.
By alternately pressing the Start and Stop buttons the Table can be jogged to any desired
position or any fraction of a revolution. For very sensitive jogging control) hold the
Stop-Button in the depressed position while operating the Start Button for jogging.

1. Start the main dril-e m-o-tor by pressing -the start button located at the right-hand
I.ear of the machine.
2. Allowi the motor to run several minutes before starting the Spindle. This will
permit the lubricating oil to circulate throughout the machine. It is advisable to turn
each of the three filter cleaner handles) located in the rear base of the machine) one complete
turn in a clockwise direction (Fig. 2B).
3. With the Clutch Levermoved to the extreme right, set shifter levers "A" and
"B" for the slowest Table speed as charted on Speed Chart) Fig. 4) page 13.
4. Move the Clutch lever to the extreme left) and the Spindle will assume its predetermined speed.
on the machines without a Ram He-ad there is only one Clutch Lever located at the
right side above the Side Head. However, machines with a Ram Head are also provided
with a Clutch IJeVer On the left Side Of the machine.
OPERATION
Feed BrclcL.e!s. The operation of all head movements is controlled by the feedworks
on which are mounted:
Hammer hand wheels for horizontal and vertical motion.

HCUT MASTERM VERTICAL TURRET LATHE
The feed clutches are engaged by moving the feed and traverse clutch handles in the
direction of desired feed.
The construction of the feed and traverse clutch mechanism has the following
advantages:
1. Hand wheels are not driven while head is being traversed, thereby safeguarding the operator.
2. The feed and traverse clutches can not be engaged simultaneously in the same
or opposite directions.
3. Both horizontal and vertical feeds may be engaged simultaneously, which
makes possible 45 degree angular cutting in any direction without swiveling the head
and without the use of special attachments.
The feed change levers are located at the outer end o1' each feed bracket. The rate
of feed is selected bv moving the feed change handles inward and outward and rotating
them so that the loco-tions of the small pins in back of the handles correspond to the desired
rate of feed as shown on the feed rate plate.

Heac!s!ocA;.. The shifting of speeds on the Cut llaster Vertical Turret lathe is by
means of hardened positive tooth clutches. All I,a.ears are in constant mesh and are never
shifted. It is, therefore) impossible to damage gears while changing speeds.
For machines with ball-shift type change, the speeds are selected by means of the
primary and secondary shift levers located adajcent to the side head. The outer lever is
ll
used for shifting the primary speeds and the inner lever for shifting the secondary speeds.
In order to shift these speeds, determine the speed desired from the speed chart mounted
on the side head and apply the brake. When t,he spindle has stopped, move the primary
or secondary lever to its new position.
If the lever can not be fully engaged) it indicates
that the clutches have landed tooth on tooth, and no amount of pressure on the lever will
engage the clutches.
When this occurs] the easiest method to engage the clutches is to simply maintain a
constant pressure on the gear shift lever while slowly engaging the clutch. It will be found
that in this way very little effort is needed) and shifts may be made very quickly and
easily.

A cutting speed chart is supplied with each Cut
Master and is mounted directly in front of the operator on the side head. The purpose
of the chart is to provide a quick and easy method for quickly determining the cutting
feet per minute.
For machines with ball-type shift speed change levers, the chart gives the position of
the levers) as well as RPM of table and cutting feet per minute.
The cutting feet per

It will be noted that the intersection of these two
lines is approximately halfway between the vertical lines which are directly under "70w
and "100w in the "Feet per Minute" column at the top of the chart. The approximate
feet per minute at the tool, therefore, is half way between 70 and 100 feet per minute or
about 85 feet per minute. It will be found that after a little practice the use of the
chart is very simple and will greatly facilitate obtaining the maximum efficiency from
the tools at all times.

To raise the cross rail, loosen the four rail
binder nuts, two of which are located on the back of each end of the cross rail) and move
the rail raising lever "Rw (Fig. 2A), mounted on the left-hand side of the bed, to the right
(in a counter-clockwise direction). To lower the cross rail,, proceed as above, but move
the rail raising lever to the left (in a clockwise direction).
The rail binder nuts serve not only to bind the cross rail to the bed, but also lock the
rail raising lever so that if any rail binder is tight) the lever can not be moved. The
purpose of this construction is to prevent moving the rail while it is bound.
In general it will not be found necessary to bind the cross rail to the bed) since the
cross rail is securely gibbed to the machine. However, for very heavy cuts) tightening
the cross rail binder nuts will result in increased cutting rigidity.
VThen the cross rail reaches its extreme upper or lower limits or approaches too closely
to the side head) the rail raising lever is automatically cammed to a neutral position, which,
however) does not prevent the cross rail from being moved in the opposite direction.
If the rail raising lever is cammed to a neutral position by the rail approaching the
side head too closely) the raft may be lowered further after the side head has been lowered.

Adjt,s!abZe At,fo77?Cl!?'C Feed Slops.
Adjustable feed stops and automatic kickouts for
safe maximum stroke are provided for each head. The feed stops consist of adjustable
dogs which may be set at any desired point. TThen contacted by the moving head) they
actuate a movable bar which trips a fixed switch.
These switches) one for vertical and one for horizontal movement) close a circuit to
actuate a solenoid and valve which in turn controls a piston unit and disengages the feed
mechanism. These stops are set when the first piece of a n.n of work is machined and will
stop feeding of the head within close limits on all subsequent pieces. These are not supposed to be micrometer stops. They facilitate the duplication of dimensions and are
part of the safety stop system) and they should not be used for finishing cuts too extremely
close. lhThere such critical dimensions must be maintainell) the stops should be set to
kickout a little beforehand and final size attained by using the hammer action of the handwheels in conjunction with the settings of the micrometer dials.
J14o67' Towrre! Head. Figure 5 shows the operation of these stops in the Main
Turret Head. On the main head the vertical motion of the slide in feed may be automatically controlled by the settings of the dogs "AH and WBw on the slideable plate "C».
These dogs are contacted by the Potable dog "DH mounted on the sbaftiWEWin the down
slide. The positions shown on the drawing) the dog "Dw will contact neither the dogs
"A" or "B" so that the operation of the automatic feed stops is disconnected.
By moving the dog "D" in a counter-clockwise direction) the dogs.,,I"A" will be
contacted, while moving the dog "Du in a clockwise direction will crfuse the dog "Bw
to be contacted. The shaft "Ew is moved inward and outward to register over each of
the five dog slots when the turret is indexed. Consequently) the head magivbe automatically stopped in any number of different positions vertically, dependin'g tifon the face of

stopping positions are required while using the same face of the turret, the proper dog "Aw
should be set for the uppermost stopping position and the corresponding dog ''B" set
for the lower stopping position. Then after the head has stopped in accordance with the
setting of the dog "Aw, the rotable dog "Dw may be tuned in a clockwise direction so
that the head will continue down until dog "D,, contacts dog "Bw.
The operation of all other stops is similar to that described above. The horizontal
motion of the main head is controlled by the settings of the dogs "Fw, wGw, and wHw,
all of which are of different heights. These dogs are contacted by the pin "I" which is
located directly under main Saddle. This pin has four positions inwardly and outwardly;
the one shown on the drawing being the extreme outward position in which no dogs are
contacted.
- By pushing the pin to its extreme inward position, the dogs "F" wiu be conti6ted.
In its next outward position, the dogs "G" will be contacted, and in its third position)

dogs "Hw will be contacted.
Both the slideable plates "Cw and wJw are designed for an
over-travel of approximately %'; therefore, after the feed has been automatically disconnected, the head may be brought to its final exact setting by hand without disengaging
the dog "D)) or the pin "I". If the 94, over-travel is exceeded, the shafts "EM or "KM
will rotate, thereby automatically throwing the stop dogs out of position. The shafts
"Ew and wKw must be retumed to their normal positions before using them further.
Under no circumstances can over-travel damage the stopping mechanism.
Sdde Head. The operation of the adjustable automatic feed stops on the side head
is shovm Qn Fig. 7. The operation of these stops is very similar to that on the
main head. In this case) h-owever) the handle "Aw may be rotated in four positions in
order to select which of the dogs-" B", "C») or "D" will be contacted. The fourth posttion of the lever "A" is neutral in which no dog is contacted. Dogs "E,I, "F", andPod3;
mounted on the right-hand side of the bed towards the back are used for automatically
disengaging the vertical feed on the side head. The selector plunger "Hw is moved inwardly and outwardly to select the proper dog.
The side head stops like the main head stops are designed to provide for over-travel)
and excessive over-travel can in no way damage the mechanism.
The plunger "I" mounted on the top of the side head is for the purpose of disengaging
the feed automatically should the side head be unintentionally fed into the cross rail, in
which case the plunger "r will contact the cam "I" mounted on the cross rail and
thereby disengage the feed.
Use a/ Stops. In general it will be found that the use of the stops will greatly
increase production) especially where a number of similar pieces are to be made. It is
generally advisable to set the stops somewhat ahead of the extreme position of the tool
and bring the head to its final position by hand. However, careful adjustment of the
stops after making several pieces will eliminate the necessity of moving the head to its
final position by hand.
For Ea;ample.. If after roughly setting the stops it is found that the head fails
to reach its final position by.018") the stop itself may be moved.018|, in which case
the size may be quite accurately held without bringing the head to its final position
by hand.

2. Loosen the saddle binder bolts and rotate the head the required number of
degrees and minutes. The wo- "AH is of such a pitch that one revolution of the
wormn shaft) (shaft "C") causes rotation of two degrees. The dial "D" is marked
in five minute intervals up to two degrees.
3. ThThen the head has been moved to its approximate position, take up the
binder bolts slightly and move the head slowly to its final position, being sure that the

backlash in the wo- is taken up in the same direction as in the original setting.
4. Clamp the binder bolts securely. The head may be moved back to its
vertical position in the same manner and if care is used in properly aligning the dial
"D" with the registry line "F") it will be found that the head may be retumed to
an exactly vertical position without difficulty.
Note: A very slight misalignment of the main head will cause taper turning. Therefore) it is very importanc that before moving the head from its original setting as the
machine is received, the above steps be carefully understood and followed.

CLLITCH AND BRAl(I ADJuSTAAENT
The Clutch and Brake is operated by a piston in the Hyd_rau|ic Speed
Snifter Unit- Cc)nstant pressure on the inner side ol the piston applies the
Clutch. Working pressure on the outer side of the piston applies the Brake.
|n the Brake pc)sition)the piston bottoms in the cylinder,. in the Clutch
position, the Outer end o£ the piston hits a Stop Screw.
This Stop Screw is
set at the factory for the proper Clutch-BI.ike throw and Should notbe a1tered.
To adjust the Clutch or Brake)remove from the Clutch Case Housing
the Cover having the oil filler spout, and proceed as follows:
CLUTCH
ADJUSTMENT:
Depress the detent pin in the Toggle Ring and turn the(Clutch)Toggle
Ring Nut one or t\x,o notches in a clockwise di=.ec:tion whenlookingtowardthe
back I)i the machine.
Each notch o£ adjustment represents approxirr}ately
.OO3 of an inch of take-up.
BRAKE
ADJUSTMENT:
Depress the detent pin in the Toggle Ring and turn the(Bral<e)Toggle
Ring Nut one or two notches in a clockwise direction when|ookingtowardthe
front ol the machine. Each notch of adjustment represents approximately
.OO3 o£ an inch of take-up.
After a Clutch oI. Brake adjustment it iS advisable to check the posttion o£ the Toggle Rolls as follows:
I.) Re-ove the Link Pin in the Clutch-Brake Operating Rod.
Z.) Using a prybar againstthe Clutch Fork,
force the Toggle Cainto engage-eat and thereby check the position ol the Toggle
Rolls to be sure thatthey are at rest onthe flat surface onthe
inside o£ the Toggle Ca-.

Opercl!¢.oro-A71gt,Zar Tt4r7".7)g.
The principal of turning angles with the T. D. A.
Unit is to simultaneously drive the horizontal feed screw in a fixed relation to the vertical
feed screw. In order to do this, it is necessary that the clutch lever "Dw be constantly
engaged and that either the horizontal feed lever "T-1 " and the vertical friction clutch
"E" be engaged simultaneously, or that the vertical feed lever "S-1 w and the horizontal
friction clutch "F» be engaged simultaneously.
EirampZe I..

J`J-J
Select the proper gears for the T. D. A. Unit as shown on drawing shipped with each
machine equipped with the T. D. A. Unit and place them on the proper studs. Move
the head to the proper starting position for the cut, but slightly away from the work,
and engage the clutch lever "D" by moving it to the right in the position marked wup
or out». Then engage the feed lever "T-1" by moving it downward. Tighten the
friction clutch "E". Start the main spindle, and the head will move along the desired
path.
If the depth of the cut is not deep enough or too deep) release the friction clutch "Ew
and adjust the vertical position of the head to the desired depth by means of the vertical
hand wheel. Retighten the friction clutch "E", set cups on both the horizontal and
vertical micrometer dials so that the same relative position can be duplicated. Engage
the main clutch and take the cut.
When the cut is completed) disengage both the vertical friction clutch wEu, and the
horizontal clutch lever "T-1 " and return the head once more to starting position again
sHghtly away from the work. Engage the horizontal feed lever "T-1" and revolve the
spindle until the micrometer dial is in exactly the same starting position as for the first cut.
Stop the spindle at this point. Move the vertical hand wheel to its original starting
position and then move it slightly further) depending on the depth of the cut which is to
be ,taken. Then re-engage the.vertical friction clutch "EH once more and proceed as
before.
Couffom..
Never engage the vertical clutch lever "Sl w while the vertical friction
clutch wEM is engaged.
3f
The operation of the T. D. A. Unit while cutting angles is entirely independent of
both the feeds and the speeds in the feedworks or the headstock. Consequently) any rate
of feed can be used while turning angles. Note that this is entirely different from the
operation of the unit when cutting threads.
E#c!mpZe 2..
To cut an angle of 60 degrees from horizontal (30 degrees from
vertical)) with tool starting at the O. D. and moving upwards and inwards.
Zi=
The same gears are used for this operation as in Example 1. However) in this case
since the angle is greater than 45 degrees, the vertical feed clutch lever "S-1 " is engaged
and the horizontal friction clutch "FH. The clutch lever "Dw is now shifted to the left
in its Down or In position. This lever of course determines the direction of motion of the
feed shaft which is connected to the T. D. A. Unit. The operation of using the T. D. A.
unit is identical to Example 1 except that the operation of all clutches is reversed.
A careful study of the chart mentioned above will fully explain the operation of the
unit. AIl angles dovm to 1 degree and 47 minutes can be turned in any direction by proper
use of the various clutches involved. In case of doubt as to which clutches to use) it is
best to operate the unit away from the work before taking a cut.
