Graduated hand wheels
   
There are four feed handles:
  • Longitudinal feed on the apron
  • Cross feed on cross slide
  • Compound feed on compound slide
  • Tailstock spindle feed handle

Each of this handles have a graduated sleeve where each line will represent a fraction of a mm.  Be aware that they differed from sleeve to sleeve on a lathe, and that different make lathes are also different.

Note:  Always take up slack in feed by moving the feed towards the work.  When touching work, sleeves can then be zeroed.

Some centre lathes is fitted with digital readout on the X and Y axis.  This means on the carriage feed and the cross feed.

Centre lathes can also be retrofitted with digital readout.  This is extremely useful as it eliminated backlash and play.  This result in increase in production and accurate work to be produced.
