LUBRICATION

The hfe and good service of a machine tool depends upon its proper lubrication, andspecial attention has been given to this important fuhction in the design of the cut MasterVertical Turret Lathes. I

Table spindle bearings, spindle gear and pinion, headstock clutch and-,brake) gearshift mechanism) and all brackets on the top of the machine with the exception of therail raising brackets are lubricated by means of a constant speed) positive displacementpump located in the bottom of the clutch case bracket. The oil is drawn from--the baseof the machine through a filter, and is then pumped under pressure to the poirits ndentionedabove from which it returns by gravity to the base.

A pressure gauge and switch are mounted on the rLcrht-hand side of the bed connectedin the main high pressure s3rvice line insuring constantlv maintained oil presstire. If anabnormal drop in pressure occurs) the main power units ;ease to function.

The feed brackets, rail raising brackets) and the gear trains within 'the various headsare lubricated independentlv from their own reservoirs in which the oil level must bemaintained.

All slide bearings and feed screws are arranged for independent pump gun I.ubrication.

SUGGESTED I:UBRICATION MAINTENANCE SYSTEM

The Bullard plant has practiced the following hit,a.hly successful lubrication controlsystem for the past five years. It has been applied to all types of -\Iachin6 Tools whichhave been produced by over thirty different -\Iachine Tool Builders and has proven to beeconomical 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 oilcharacteristics.

i Laboratory reports are used as a basis for determining sampling and changeperiods.

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 checkperiod will be determined by experience.

7. We Cha,nge Otl When the Nentralizckon N"mbe1. ReaiI..es 0.5 (Mithgrorms of KOHper 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 accumu-lated sludge and dirt.

9. 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 changedmore cheaply than the a.ost of tests to determine the condition of the oil. We changethem,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-handside of the machine. The start-button must be held in t,he depressed position for a fewseconds to allow the oil lubrication pump to build up a sufficient pressure to operate apressure 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 Brakeposition 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 withthe Pendant. With this arrangement the spindle will not start until one of these Startswitches fL1.e energized.

The spindle may be stopped by either energizing one of the Stop buttons or byswitching the Clutch Brake switch on the Pendant to the Brake position.

There are many cases which require jogging of the table for positioning and indicatingpurposes. 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 desiredposition or any fraction of a revolution. For very sensitive jogging control) hold theStop-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-handI.ear of the machine.

2. Allowi the motor to run several minutes before starting the Spindle. This willpermit the lubricating oil to circulate throughout the machine. It is advisable to turneach of the three filter cleaner handles) located in the rear base of the machine) one completeturn 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 pre-determined speed.

on the machines without a Ram He-ad there is only one Clutch Lever located at theright side above the Side Head. However, machines with a Ram Head are also providedwith a Clutch IJeVer On the left Side Of the machine.

HCUT MASTERM VERTICAL TURRET LATHE

The feed clutches are engaged by moving the feed and traverse clutch handles in thedirection of desired feed.

The construction of the feed and traverse clutch mechanism has the followingadvantages:

1. Hand wheels are not driven while head is being traversed, thereby safe-guarding the operator.

2. The feed and traverse clutches can not be engaged simultaneously in the sameor opposite directions.

3. Both horizontal and vertical feeds may be engaged simultaneously, whichmakes possible 45 degree angular cutting in any direction without swiveling the headand without the use of special attachments.

The feed change levers are located at the outer end o1' each feed bracket. The rateof feed is selected bv moving the feed change handles inward and outward and rotatingthem so that the loco-tions of the small pins in back of the handles correspond to the desiredrate of feed as shown on the feed rate plate.

Heac!s!ocA;.. The shifting of speeds on the Cut llaster Vertical Turret lathe is bymeans of hardened positive tooth clutches. All I,a.ears are in constant mesh and are nevershifted. It is, therefore) impossible to damage gears while changing speeds.

For machines with ball-shift type change, the speeds are selected by means of theprimary and secondary shift levers located adajcent to the side head. The outer lever is



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 mountedon the side head and apply the brake. When t,he spindle has stopped, move the primaryor secondary lever to its new position. If the lever can not be fully engaged) it indicatesthat the clutches have landed tooth on tooth, and no amount of pressure on the lever willengage the clutches.

When this occurs] the easiest method to engage the clutches is to simply maintain aconstant pressure on the gear shift lever while slowly engaging the clutch. It will be foundthat in this way very little effort is needed) and shifts may be made very quickly andeasily.

C/t,#trog SpeecZ Chclr!. (Fig. 4.) A cutting speed chart is supplied with each CutMaster and is mounted directly in front of the operator on the side head. The purposeof the chart is to provide a quick and easy method for quickly determining the cuttingfeet per minute.

For machines with ball-type shift speed change levers, the chart gives the position ofthe levers) as well as RPM of table and cutting feet per minute.

Ezc!77?P!e I.. If a cylinder25y in diameter is to beturned at 150 ft. perminute) the proper tablespeed and the headstockshift lever positions aredetemlined aS follows:

Follow the horizontal lineopposite "25" in the "Di-ameter of Work in Inches"column, found on the left-hand side of the chart) tothe right until it intersectsthe vertical Hne directly be-low "150" in the "Feetper Minute" column foundat the top ofthechart. Theintersection of these twolines falls on a diagonalline. By following this di-agonal line upwards to theright, it will be found thatthe proper headstock gearshift leverposition is ((C w-2,and the spindle speed is 22.5R.P.M.

Ezomp!e 2.. If a cut is being taken on a 35# diameter with the headstock shiftlevers in position "B-1 H) the feet per minute at the tool may be dete-ined as follows:

Follow the diagonal line opposite "B-1H dovmward to the left until it crosses thehorizontal line opposite "35u found in the "Diameter of Work in Inches" column onthe left-hand side of the chart. It will be noted that the intersection of these twolines is approximately halfway between the vertical lines which are directly under "70wand "100w in the "Feet per Minute" column at the top of the chart. The approximatefeet per minute at the tool, therefore, is half way between 70 and 100 feet per minute orabout 85 feet per minute. It will be found that after a little practice the use of thechart is very simple and will greatly facilitate obtaining the maximum efficiency fromthe tools at all times.

To raise the cross rail, loosen the four railbinder nuts, two of which are located on the back of each end of the cross rail) and movethe 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 movethe 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 therail raising lever so that if any rail binder is tight) the lever can not be moved. Thepurpose 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 thecross rail is securely gibbed to the machine. However, for very heavy cuts) tighteningthe cross rail binder nuts will result in increased cutting rigidity.

VThen the cross rail reaches its extreme upper or lower limits or approaches too closelyto 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 theside 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 forsafe maximum stroke are provided for each head. The feed stops consist of adjustabledogs which may be set at any desired point. TThen contacted by the moving head) theyactuate a movable bar which trips a fixed switch.

These switches) one for vertical and one for horizontal movement) close a circuit toactuate a solenoid and valve which in turn controls a piston unit and disengages the feedmechanism. These stops are set when the first piece of a n.n of work is machined and willstop feeding of the head within close limits on all subsequent pieces. These are not sup-posed to be micrometer stops. They facilitate the duplication of dimensions and arepart of the safety stop system) and they should not be used for finishing cuts too extremelyclose. lhThere such critical dimensions must be maintainell) the stops should be set tokickout a little beforehand and final size attained by using the hammer action of the hand-wheels in conjunction with the settings of the micrometer dials.

J14o67' Towrre! Head. Figure 5 shows the operation of these stops in the MainTurret Head. On the main head the vertical motion of the slide in feed may be auto-matically 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 downslide.

stopping positions are required while using the same face of the turret, the proper dog "Awshould be set for the uppermost stopping position and the corresponding dog ''B" setfor the lower stopping position. Then after the head has stopped in accordance with thesetting of the dog "Aw, the rotable dog "Dw may be tuned in a clockwise direction sothat the head will continue down until dog "D,, contacts dog "Bw.

" -,. The operation of all other stops is similar to that described above. The horizontalmotion 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

dogs "Hw will be contacted. Both the slideable plates "Cw and wJw are designed for anover-travel of approximately %'; therefore, after the feed has been automatically dis-connected, the head may be brought to its final exact setting by hand without disengagingthe dog "D)) or the pin "I". If the 94, over-travel is exceeded, the shafts "EM or "KMwill 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 headis shovm Qn Fig. 7. The operation of these stops is very similar to that on themain head. In this case) h-owever) the handle "Aw may be rotated in four positions inorder to select which of the dogs-" B", "C») or "D" will be contacted. The fourth post-Pod3;tion of the lever "A" is neutral in which no dog is contacted. Dogs "E,I, "F", andmounted on the right-hand side of the bed towards the back are used for automaticallydisengaging the vertical feed on the side head. The selector plunger "Hw is moved in-wardly 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 disengagingthe feed automatically should the side head be unintentionally fed into the cross rail, inwhich case the plunger "r will contact the cam "I" mounted on the cross rail andthereby disengage the feed.

Use a/ Stops. In general it will be found that the use of the stops will greatlyincrease production) especially where a number of similar pieces are to be made. It isgenerally advisable to set the stops somewhat ahead of the extreme position of the tooland bring the head to its final position by hand. However, careful adjustment of thestops after making several pieces will eliminate the necessity of moving the head to itsfinal position by hand.

For Ea;ample.. If after roughly setting the stops it is found that the head failsto reach its final position by.018") the stop itself may be moved.018|, in which casethe size may be quite accurately held without bringing the head to its final positionby hand.sti)tuez?ng a/ R¢tZ Heeds.

Engage main clutch and when spindlerevolving at proper speed, engage clutch lever"Dw which operates a single tooth clutch.VIThen the tool has reached the eh,d of its firstthreading cut, back the head out 'of the threadby means of the horizontal hand wheel. Neu-tralize the clutch lever "Dw and return thehead to its starting position by means of powertraverse lever "S-1H. The head may then bemoved in a little further to take the secondthreading cut and the clutch lever "DH oncemore engaged.

Because of the design of the clutch whichis operated by the clutch lever "D),, the threadchaser always picks up the oriSnal thread with-out any danger of splitting the thread.

Cowf¢'on.. Neverengage clutch and traversehandles "T-1" or "S-1W in their feed positionswhen cutting threads.

If it is necessary to pick up a thread at agiven position or to recut an old thread, thethread chaser may be accurately positioned inthe cut by first engaging the clutch lever ''Dl,with the vertical friction clutch "E" dis-engaged, nlnning the spindle One Or more

|n the Brake pc)sition)the piston bottoms in the cylinder,. in the Clutchposition, the Outer end o£ the piston hits a Stop Screw. This Stop Screw isset at the factory for the proper Clutch-BI.ike throw and Should notbe a1-tered.

To adjust the Clutch or Brake)remove from the Clutch Case Housingthe 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 whenlookingtowardtheback 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|ookingtowardthefront 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 post-tion 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 Ca-

revolutions to take the backlash out of the T. D. A. Unit, and then positioning the chaseraccurately in the thread with the spindle stopped. Then by tightelring the Verticalfriction clutch "E w) the head will automatically follow the original thread.

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 verticalfeed screw. In order to do this, it is necessary that the clutch lever "Dw be constantlyengaged 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 horizontalfriction clutch "F» be engaged simultaneously.

EirampZe I.. To cut an angle of 30 degrees from the horizontal) with tool start-ing at the O. D. and moving upwards and inwards.

Select the proper gears for the T. D. A. Unit as shown on drawing shipped with eachmachine equipped with the T. D. A. Unit and place them on the proper studs. Movethe 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 wupor out». Then engage the feed lever "T-1" by moving it downward. Tighten thefriction clutch "E". Start the main spindle, and the head will move along the desiredpath.

If the depth of the cut is not deep enough or too deep) release the friction clutch "Ewand adjust the vertical position of the head to the desired depth by means of the verticalhand wheel. Retighten the friction clutch "E", set cups on both the horizontal andvertical micrometer dials so that the same relative position can be duplicated. Engagethe main clutch and take the cut.

When the cut is completed) disengage both the vertical friction clutch wEu, and thehorizontal clutch lever "T-1 " and return the head once more to starting position againsHghtly away from the work. Engage the horizontal feed lever "T-1" and revolve thespindle 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 startingposition and then move it slightly further) depending on the depth of the cut which is tobe ,taken. Then re-engage the.vertical friction clutch "EH once more and proceed asbefore.

Couffom.. Never engage the vertical clutch lever "Sl w while the vertical frictionclutch wEM is engaged.

The operation of the T. D. A. Unit while cutting angles is entirely independent ofboth the feeds and the speeds in the feedworks or the headstock. Consequently) any rateof feed can be used while turning angles. Note that this is entirely different from theoperation of the unit when cutting threads.

E#c!mpZe 2.. To cut an angle of 60 degrees from horizontal (30 degrees fromvertical)) with tool starting at the O. D. and moving upwards and inwards.

The same gears are used for this operation as in Example 1. However) in this casesince the angle is greater than 45 degrees, the vertical feed clutch lever "S-1 " is engagedand the horizontal friction clutch "FH. The clutch lever "Dw is now shifted to the leftin its Down or In position. This lever of course determines the direction of motion of thefeed 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 theunit. AIl angles dovm to 1 degree and 47 minutes can be turned in any direction by properuse of the various clutches involved. In case of doubt as to which clutches to use) it isbest to operate the unit away from the work before taking a cut.
