Screw down the adjustable feet to each take its share of the load without losing ground contact at any other foot. Lock the adjustable feet. 3. Run the lathe. Any evident vibration will be due to incorrect setting of the adjustable feet; and this can be eliminated by slight alteration of the setting whilst the machine is running. Re-lock the adjust-- able feet. 4. For all normal operating requirements, the mount- ing as described will give allthe support necessary. CHUCK MOUNTING 5.
lt is essential that the machine is correcfly leveiled before using it in production and each- time an adjustment is made to the foundation bolts or mounting feet. A precision engineers'level should be used and readings taken across headstock and tailstock ends and then in two positions on both front and rear bed shears in a longitudinal direction. Careful attention to levelling will greafly add to the accuracy of work produced and to effibient life of the machine. lf the foundation is not accurate and level it may be necessary to adjust the levelling screws provided at the base of the cabinet, ]fe A.S.,A.
long-taper key drive spindle nose (to L1 standard) is incorporated on this machine ahd has been selected in order to overcome the danger of chuck or faceplate detachment when the spindle is stopped or reversed rapidly. Before fitting a chuck to the spindle nose, ensure that the centre and centre bush have been removed, Care should be taken to make sure that the taper and the key of the spindle nose, together with the internal tapered bore of the chuck, are scrupulously clean. Any dirt, swarf or burrs on these surfaces will upset the accuracy of the machine, may prevent the coirect locking of the chuck on the spindle nose and can cause irremediable damage to the mating surfaces.
The spindle nose drawnut engages with the thread on the back of the chuck: and when the drawnut has been screwed up by hand, without trouble, the special spanner wrench supplied with the machine should be used to tighten the drawnut fully. lt is advisable to give the stock of the Spanner wrench one or two sharp blows with a mallet to ensure that the drawnut is quite tight. Do not, however, fit extension handles over the spanner wrench for tightening purposes. BOLTING DOWN 1, Position the lathe level upon the three fixed feet (shown in the installation plan as FF). 2. Screw down the adjustable feet to each to take its share of the load without losing ground contact with any other foot.
Lock the adjustable feet. 3. Insert ff;in diameter foundation bolts through the bolt positions provided and into cleanly drilled holes in the concrete foundation. When inserted. they should be firmly secured within the foundation before attempting to tighten the holding-down n uts. 4. Secure the holding-down nuts firmly but avoid overtightening. Bolt tension should be just sufti- cient to retain the machine in position without disturbing the cross-wind alignmbnt. 5. Run the machine. Any evident.vibration will be due to incorrect setting of the adjustable feet which can be remedied by slackening all mounting bolts and altering the adjustment a little at a time.
Care and attention given to obtain the correct setting at this stage will be well repaid. Re-lock the adjust- able feet before tightening the mounting boltd. 6. lt is essential that the machine is correctlv levelled before using it in production and each- time an adjustrnent is made to the foundation bolts or mounting feet.
