3.1 SLINGING OF THE MACHINE :Figure 2 and 3 shows the lifting arrangement of LATHE MACHINE. To achieve balancetailstock and carriage should be moved to position shown and adjusted if required.Item recommended lifting :# Hemp rope dia. 40mm x 16mm long.# Wooden blocks size: 100 x 100 x 200.# Quantity-1
3.2 CLEANING OF THE MACHINE :Remove the anticorrosive coating from all side-ways, lead screw, rack & end train, etc,Using kerosene. Oil all bright machined surfaces immediately there after. Use heavy oilon the end gears. At the end of day work, clean machine carefully, do not use compressedair. Never use fluffy or cotton Waste. Though cleaning should be undertaken once a weekafter using very long production. Avoid uneven wear of the guide ways.
3.3 INSTALLATION :The machine should be unstained at a place, which provides sufficient room for its operationand maintenance. (See figure on page 2) The lathes can be free standing on hard andstable shop floor. Depth of foundation Depends on quality of floor but should be 400mm(min).
Foundation bolts : Diameter 16 mm x length 400 mm
3.4 LEVELING :The machine should be geometrically leveled before it put in to the operation. Alignmenttaste and accurately to the values specified in the Taste chart of this machine, will shownafter precision level. The foundation bolts are to be grouted and facilitate proper grouting.Between base plate and foundation. Foundation bolts should be tightened gently anduniformly without disturbing the level of the machine. Recheck bed level after tighteningthe foundation bolts. Periodically check bed level to ensure contained lathe accuracy.# Use spirit level accuracy of 0.05 mm/mt. (RSK Japan, Mitutoyo or Equivalent)
The machine must be leveled accurately to the values specified in the test chart (suppliedalong with the machine). Use precision level graduated to 0.02 mm per meter (SRK Japanmake or equivalent). Follow the procedure given below for accurate leveling.
Transverse Level A :Keep the precision level on cross slide transverse position. (A)Take the carriage to head stock end, adjust the bubble in precision level approximately asper shown in centre by adjusting leveling bolts.Move the carriage to tailstock end, and adjust the bubble as per same reading shown nearheadstock end, by adjusting the leveling bolts.Make both the readings at headstock end and tailstock end to be identical and same. NOTWIST OF BED IS PERMITTTED.
All Geared Lathe Machine
Page : 8
Longitudinal Level B :After setting the Transverse level as per (A) Do not adjust the leveling boltsMove the carriage to the centre of bed.Put the precision level on cross slide top on front ‘V of bed in longitudinal position (B).Ensure the bubble position approximately at the centre of the level. Use: Thin paper, ifrequired for marking.Move the carriage near to headstock and then to tailstock side and ensure the variation.Recheck the transverse level.
After properly leveling the machine, run the machine for about 2 hours at various speedand check levels. Reset if required.
Then the foundation bolts are grouted in the large holes, with 1:3 cement and sand mixture.Sufficient time should be allowed for the concrete to cure (3-4 days). The foundation boltsare tightened gently. Periodically check up bed level to ensure continued lathe accuracy.
3.5 LUBRICATIONS IN LATHE MACHINE :
3.5.2 FEED GEAR BOX :All drive elements in the feed gear box are splash lubricate. Oil pouring and drain pointsare at top and beneath to gear box. Oil silted glass is to maintain the level in feed gear box.Use servo gear oil H.P. 90 or equivalent.
3.5.3 APRON & CARRIAGE :Apron drive and saddle guide ways are lubrication by mean of hand lubrication pumpTWISE A DAY. An oil hole in apron at right hand to pour sufficient oil till the level. Thereis a drain plug in the beneath of apron. The dial indicator should be lubricated use servogear oil H.P. 90 or equivalent.
3.5.4 END GEAR TRAIN :Pour oil on the end gear train everyday by an oil gun. Use servo gear oil H.P. 90 orequivalent. Following area’s and item’s are lubricate through oil nipple’s everyday by oilgun.

Pouring3.5.1 HEAD STOCK :Head stock drive is splash lubricated, with oilstored inside head stock. The channel is connectedto front and rear bore at the top for properlubrication of spindle bearings. Oil shows up inlevel glass at the side of head stock.
Oil pouring is from top cover 1/2 bolt and drainpoints are at left side of head stock. Change oilevery 8 months. Maintain the oil level and usealways servo system 32 grade oil or equivalent.Use of in correct grade of oil cause damage.

While cutting lengthy screws, the half nuts required to be disengaged at the end of eachcut to bring the carriage quickly to the starting position for subsequent cut. This indicatoris useful to engage the half nuts at correct time, while cutting screws during beginning ofeach cut. So that the tool will follow original helix that is formed during previous cuts.
The recommended graduations on the dial in the column 3 coincide with the fixed pointon the bracket. This dial indicator is not useful for cutting other pitches Metric, Moduleand DP thread. While cutting these threads the tool should be with drawn withoutdisengaging the half nuts ant the end of each cut and spindle rotation should be reversedto bring the carriage (tool) to the starting position for subsequent cuts.

5.6 GEAR NOISE :In spite of the monumental research work done the subject given noise (as well as measuresfor it’s reduction) is one of the least understood areas of gear technology. Even if all therelevant machining instructions, tolerances, and other factors are observed faithfully, theseis no guarantee that a noiseless gear set will result. Generally speaking, the noise level atthe work place should be as possible. In case of various gear drives, certain guiding valuesfor intensity of sound can be given which have been measured at a distance of 500 mm.And which are usually encountered in industries. Rigid standards for permissible gearnoise have not been made, but the “American Gear Manufacturers Association” (AGMA)has given the following provisional noise limit for high speed helical and herringbonegear-sets.
(1) 107 db between 20 and 75 Hz
(2) 99 db between 75 and 150 Hz
(3) 94 between 150 and 300 Hz
(Here db (decibel) is the unit of sound level and Hz (hertz) for the frequency.)

5.7 POSSIBLE OPERATIONAL DIFFICULTIES AND REMEDIES :CAUSE OF INACCURATE TURNING :
Almost always the cause of inaccurate turning is faulty alignment of lathe. Theimportance of accurate alignment and proper grouting cannot there for be over lookedif, in spite of this, inaccurate turning occurs after some time, it is possible that thegibbs of the slides or the nut of the cross slide screw require adjustment, provided always thatthe cutting tool is properly clamping and does not vibrate. Chattering on lathes especiallywhen turning overhang, can be avoided by changing the speed and feed as the possiblethat in this case the critical speeds of machine and work piece ate the same. If a change if feedor speed does not step the chattering, it may be due to any of the following reasons.
To employ proper speed and feed.Improper leveling of the lathe.The work-piece is over hanging too far; a steady rest should be used.Slender components being machined without proper supports by steady rest.The legs are not properly grouted.Back plate of chuck not fitted properly.The gibes of the slide need adjustment.Dirt between spindle nose taper and center-holder.The cutting tool overhanging too far.The cutting tool is not clamped firmly.Un-balanced fixture of work-piece cause vibrations especially at high speed.Check the cooling and the coolant.
SPINDLE RUNS TOO TIGHTLY AND BEARINGS BE COME TOO HOT IN THE HEAD STOCK.
1. Check the bearing lubrication portion and see whether it needs to be or not. Use recommendedgrade of oil.
2. Loosen the check nuts of spindle and adjust the bearing.
CON PULLEY JAMMING ON MAIN SPINDLE AND BACK GEAR JAMMING.
1. Check spindle lubrication if lubrication is in sufficient, remove two screws (at rightangles) provided on the pulley diameter and fill recommended oil unit it over flowsfrom the other hole.
2. Clean the roughly and lubricate the back gear assembly.

As per IS : 1878 (PART 1) 1971PRACTICAL TESTS
(All Dimenstions are in Millimeters)
# Hardness of Bed - BHN
Note : The specification concerning local tolerance are given only to eliminate in case of linersideways, the possibility of too large deviations in straightness concentrated on a smalllength. (2.3.2.2 (d) of IS : 2063-1962 code for – testing machine tools)
However, in the case of slide ways with a regular convex which is approximatelysymmetrical with respect to the middle of their length, the specifications for local toleranceare too respective at the extremities of the slideway. In such cases the specifications forlocal tolerance may be doubled for the outer quarters of the slideway.
