LEVELLING

The precision, rigidity and durab"ity Of the lathe depend on careful leveHing.

our final inspection tests conform tO ISO/DR l708 standards and can only be

repeated when the lathe is correctly levelled-

lt is not absolutely necessary that the bed be transversally and longitudinauy

horizontal. But it is important that the COnditiOnS Of the first levelling check

be applied to subsequent levelling, thus making all checks on the same plane.

No torsion or warping Can be tolerated unless it is within the Hmits of lSO/DR

1708 standards.

For love"ing the machine (See figure On OPPOSite Page) use a Precision level

(4) with a sensibility of 0.02 mm/meter (0.00025 inch/foot) and two paraHel

bars (5). Take readings at the indic.ated points always using the Same Parallel

bar on the same slide way.

Loosen nuts (1) and locknuts (3).

Adjust with screws (2).

verify longitudinally positions A and B.

verify transverse"y with level resting on paraHel bars in positions a and

D.

Tighten nuts (1) and locknuts (3).

Recheck level (4).

NOTE:- lt is advisable to check the levelling after the first working week tO

verify the soundness of the foundation and afterwards have a check every

six months.

lNSTALLATION OF CHUCK ON CAtuOCK SPINDLE NOSE

REFERENCE llA H

Before counting the Chuck, the bore and nose Should be thoroughly cleaned andwiped to rerove any a" or grease- upon mounting the chuck, rrBke Sure the line (D)on the c.hack coincides with the reference line (D) on the spindle. Optional seereferent.e ll B u.

with the proper wrench, turn a" lock pins, one by one untH they are slightlytightened to enable the preliminary location of the chuck On the nose. Now tightenall lock pins to obtain perfect fitting of the chuck to the nose.

Normal clearance Of Chuck face and SPindle face lS approximately 0.I mm(0-003937").see the illustrations and nrake sure Of the correct POSitiOn for tightening lockpins. with camlocks engaged, the force fitting is now a few hundredths of amillimeter betveen chuck face and SPindle face.

REFERENCE u B "

ln the event a chuck is different from the one supplied with the machine thecounting procedure is as follows:

. check thecorrect positionofall lockpinson thechuck (A, B and I).

. place chuckon spindle and check lf lock pins when tightened are in correctposition. otherwise, adjust each pin ac.cordingly.

. After this operation and upon Checking that the Chuck iS correctly tightened,make a reference mark on the chuck which w"I coincide with a reference mark onthe spindle to assure that the chuck is always mounted in this same position.

NOTE A chuck from another lathe should not be nrountedthe correct position of lock pins.

REMOVING CAMLOCK CHUCKS

before first checking

Turn lock pins One by One, until the lines coincide. With a wooden maHet hit thechuc.k from the rear until it is loosened from the SPindle rose.

APRON OPERATION

Cross and longitudinal feeds are engaged by a t\^K) position Single lever (I) withfrontal gear meshing to provide the respec.live feeds.

The corm gear and pinion is driven by the feed rod and is assembled inside a boxlocated in the rear side of the apron. This unit is readily accessible forcleaning and eventual repairs without disassembling the complete apron. lt is,however, nec.essary to remove the apron from the machine.

The operation of the half-nut (2) that is engaged to the leadsc.rew is act.omplishedthrough lever (3) located on the right side of theoperator.

Handwheel (4) for manual operation of the apron is located at the left side of theapron and it is disengaged by pulling it out.

All shafts are mounted on bearings and lubricated by an automatically operatedpump} when the feed rod is in operation. Oil is pumped to the reservoir located onthe upper part of the housing and gravity fed through piping to the points to belubricated.

The aprcln incorporates a precision automatic disengagement system (5) which isaccomplished by the disengagement of the feed gears against a spring. When theapron touches the solid stop} the effort exerted by the feed rod overcomes thespring force and disengages practically without variation. Through knob (6) therequired effort is select when light or heavy cuts are taken.

Manual pump (7) provides lubrication for saddle guide rays and crc)ss Slide Ways.

TA ILSTOCK

The tailstock is manually moved along the bed and is clamped in position on the bedby means of lever (I) located close to the handwhee1.

When " setting-over " the tailstock from the center line of its base, adjust thealignment with the headstock center by means of the tro screws (2) lot.ated at thebase of the tailstock body. One adjusting screw (2) is located in the rear.

A scale (3) located at the base, below clamping lever (I) is used to measure the" set over ". Each division corresponds to I mm.

Before the adjustment, the tailstock must be unclamped by actuating love.r (I).

The quill is clamped through lever (4).

CLAMPING OF TAILSTOCK

To increase clamping force of tailstock to the bed. proceed as follous:

I. Release clamping lever (1).2. Tighten manually nut (5) located under fixing claw (6) until desired positive

clamping force is obtained.

lf the maJ'Ority Of turning OPeratiOnS dO not require COnSiderable clamping force toavoid slippage, reduce clamping force by following above instructions in the rever-se_

This practice, besides reducing manual clamping and unclamping efforts, it wiuensure lesser elastic. strain to the structure providing| therefore long timeaccurac.y and repeatability in any kind of production work.

LIMIT BLOCK FOR AUTOtIATIC DISENGAGING, AND SAFETY CLUTCHES

The limit block is fitted on the bed vee slide between the apron and headstock bymeans of screws (1).

Regulating the position for automatic disengaging of the apron for distances lessthan I 3/8" is made byadjustingoneof the four sc.rews (2) in the drum fitted inthe side of the apron. For distances over I 3/8H the adjustment is made on thebar (3).

A safety clutch is fitted on the extreme left of the lead screw (4). The purposeof this clutc.h is tc) eliminate any possible damage that c.ould be caused if theoperator allowed the apron to hit against the limit blockwhilst thread cutting.This clutch has been regulated at the factory and must never under anycirc.umstanc.es be used to limit the pass whilst thread c.utting.

The safety device against longitudinal and transversal feed overloads isincorporated within the apron met.hanism.

HEADSTOCK

ustin main S indle end play

Main spindle is supported on tapered roHer bearings that provide smooth and

accurate operation of the headstock for a very long time even under hard

working c.onditions.

The spindle bearings are carefu"y adjusted before the lathe is shipped from

the factory and unless absolutely necessary this adjustment should not be

changed. lf the customerls requirements should differ from the origlna1, then

proc.eed as follows:

Run the headstock Slowly at first and then faster for about an hour until

bearings reach normal working temperature.

Remove rubber mat (I) and COVer (2).

Loosen lock nut (3).

Gradua"y t;ghten adjusting nut (4) and make sure the spindle rotates

smoothly by hand. Adjust until bearings are free of all end play.

Tighten lock nut (3) against nut (4).

To rec.heck rotate the SPindle by hand. Some resistance shc)uld be noticed

when using one hand on the left end.

lf necessary repeat this proc.edure.

Replace cover (2) and rubber mat (1).

lf bearings are replaced, fo"ow the above instructions for adjusting the new

bearings.

since these bearings are of the high precision type' it ls recormended that

this service is performed only by hi skilled servicemen.

After lc)ng use, main motor belts may become slack, requiring adjustment. This iseasily accomplished as follows:

. opendoor (I).

. Loosennut (3).

. Tighten nut (2) until correc.t belt tension is obtained.

I To c.heck whether the tension iS COrreC.t Place a straight edge over theoutside diameter of the pulleys.

a Apply Hght finger pressure on the belts which, when properly tensioned, wiumove from I/4" to 3/8ll from the straight edge.

. Tightennut (3).

BRAKE

MEASURING THE AIR CLEARANCE

with the c.ontinued use of the lathe} the brake friction lining wears and the air

clearance increases.

To assure perfect operation of the brake} the air clearance must not be more than

0.024H. lf theair clearance exceeds this measure) wear will c.ontinue and the

disc will not be attracted enough to actuate the brake.

ADJUSTING THE AIR CLEARANCE

See figure below and proceed as follows:

- Remove cover (1).

Thread and feed ear box

The thread and feed gear box is operated through heat treated gears with the

majority of its shafts supported by bearings. Lubrication is acc.omplished

through a pump operated by an eccentric located on one of the driving shafts-

The design of the thread and feed gear box makes it possible to obtain a wide

range of both metric and inch feeds and threads without changing the end

gearing-

The same range of module and diametral pitc.h threads is obtained by

repositioning one gear in the end gearing (see page p8297lB47/47).

When a partic.ular thread or feed is desired, selec.t the desired thread in the

chart lot.ated on the box. ln the same column and same line youwill find the

letters that will position the controls (3, 5, 6, 8 and 9).

Example I:- Tocut a metric thread of 1 mm pitch:

a). find pitch 1 in thechart,

b). by foHowing the arrows in the figure, all Indications

required for positioning the controls are found.

c"ial m ''s set ''n pos''tion |IIIII

The mac.hine is prepared for cutting 1 mm pitch threads.

Example 2:- Feed of 0.250 mm per revolution:

a). dial (7) is set in position RAb). position all other controls as indicated in example I-

NOTE:- To positic)n dial (9) pre-selectorof threads and feeds, it is

required that lever (8) is in neutral position, that is, ln center

position.

p8297l B49/49


Thread dial indiC,atOr (6 mm pitch Ieadscrew)

This clial shows the point at whlc.h the half-nut must be engaged in order thata" pitches necessary to c.ut a thread will coincide with the initial pitch.

The dial is provided with an engraved face Showing Six POSitiOnS and three (3)

gears z=12, Z-14 and z=15.

This device must be used according tO the Chart below:
