For sofe lif,ing the slings should be arranged as shown above. When leaving our plant the saddle is positioned for balanced lifting and should not be moved. Avoid setting the machine down hard on the floor oHieiwise accuracy may be impaired.

REMOVAL OF RUST PREVENTATIVE (See Section l. l)

All parts subject to corrosion ore protected by a rust preventative. This can be removed with white spirit or turpentine. Do not use o scraper or any instrument liable to damage machined surfaces. Do not use petrol (gasoline) or paraffin (kerosene),

NOTE: IF CHAINS ARE USED FOR LIFTING INSERT WOOD PACKING TO PREVENT DAM)\GE TO BEDWAYS AND SHAFTS.

2.5 LEVELLING

Your lathe ~ill only tum accurately if attention is given to accurate levelling . Use only a precision spirit level reading o. 000511 in 1011

•

The level should be placed crosswise on saddle top and lengthwise on the back way of the bed, the saddle being moved along the bed for checking crosswise at the different positions. ( If hydrau I ic copying, remove the front compound slides and place the level on top of tl.e cross slide.) The bed should be levelled initially in the crosswise direction and from end to end in thelengthwisedirectionusingthefrontand rear adjusting screws at extreme ends of lathe only . When this has been done move the saddle up to the chuck, tighten the front screw at 1A1 until the bubble in the level just moves i.e. (2 - divisions if level reads 0.000511 per division in 1011

) and bring back to level using corresponding rea r screw.

NOTE. Locknuts on adjusting screws should be tightened after each adjustment, It is also desirable to keep the machine as near the floor as possible.

When level ling tests are correct the holding down bolts shou Id be tightened and the level re­checked. At no time should levelling be corrected with the holding down bolts nipped tight, It should be realised that the whole purpose of the levelling operation is to endeavour to reproduce the conditions underw hich a lathe has been built and inspected at the D.S. G, plant. Here all testing isdonewith the bed levelled but not bolted down and therefore, free from stress • The level of the lathe should be checked periodically, say every six months,

TURNING TEST.

Before running read carefully sections 3, 4, & 5, Takea finishing cut a long a barprojecting 12" from the chuck and check diameter by micrometer. The bar should be porallel to within .000411 on d iameter in 911

• If outside this limit check on topandsideofbar using a dial indicator from saddle as parallelism of spindle test on inspection sheet, allowing for taper of bar. Adjust levelling screws of extreme LEFT HAND END of the bed only to correct any inaccuracy. Take a further light cut to check result.

2.5 LEVELLING

Your lathe wiU only tum accurate ly if attention is given to accura te levelling . Use only a precision spidt level reading 0-000511 in IO".

The level should be placed crosswise on saddle top and lengthwise on the back way o f the bed, · the saddle being moved a~long the bed for checking crosswise a t the different posi tions. (I f

hydraulic copying, remove the front compound slides and place the level on top of tLe cross slide .) The bed should be levelled initially in the crosswise direction and from end to end in the lengthwise direc t ion using the front and rear adjusting screws at extreme e.n.ds of lathe only. When th is has been done move the saddle up to the chuck, tighten the front screw a t 'A' until the bubble iri the level just moves i. e . (2 - divisions if leve l reads 0.000511 per division in 1011

) and bring back to level using corresponding rear screw.

NOTE. Locknuts on odjusiing screws should be tightened after eoch adjustment. It is a lso desirable to keep the machine as neor the floor as possible

When leveUing tests are correct the holding down bolts should be tightened and the leve l re­checked. At no time should levelling be corrected with the ho.lding down bolts nipped tight, It should be realised that the whole purpose of the levelling operation is fo endeavour to reproduce the conditions underwhich o lathe hos beeh built and Inspected at the D. S. G . plant. Here a II testing is done w i rh rhe bed levelled bot not bolted down end therefore, free from stress • The leve.1 of the lathe should be checked pericx:lically, say every six months.

TURNING TEST,

Before running read carefully sections 3, 4, & 5. Take a finishing cut a long a bar projecting 1211 from the chuck and check diameter by micrometer . The bar should be parallel to within .000411 on diometer in 911

• If outside this limit check on topond sideofbor using a dial indicator from saddle c s para llelism of spindle test on inspection sheet, allowing for taper of bar. Adjust levelling screws of extreme LEFT HAND END o f the bed only to correct any inaccuracy. Take o Further light cut to check result .
