Page 17: Operation
OPERATION SIMPLE TURNING Before starting the machine, it is imperative that the setup for the type of work to be carried out is fully checked. The following notes are guidelines as to how to set up the lathe in order to carry out a simple turning operation. - Page 18 Whilst carrying out these manoeuvres, rotate the chuck by hand to ensure that nothing will come into contact with it when turning takes place, i.e. there is adequate clearance between the saddle, cross-slide, tool post or cutting tool, and the chuck. It may be necessary to adjust the position of the compound slide or reposition the work in the chuck to guarantee that there is adequate clearance.
- Page 19 until you reach the previously marked line on the work, then retract the tool one or two complete turns on the Cross-Slide feed handle. Wind the saddle back to the beginning then wind the tool the same number of turns ‘IN’, plus the depth of desired cut, and proceed to cut once more. NOTE: This describes the procedure for general rough cutting.
