Lathes can be ordered new with factory installed digital readouts. The digital readouts are applied to the leadscrew and the crosslide screw. The sensors read handwheel rotation and electronically translate that into table movement on a digital display that reads out to the nearest .0005”. Backlash can be compensated for electronically, also to within .0005”. Because the movements on a lathe of this size are relatively small and the precision rolled leadscrews are highly accurate, this is system works very well while keeping costs down. In addition to reading the travel of both axes, the readout box also provides a continuous readout of spindle RPM.

Please note the picture shows the 4000A-DRO package which includes several options that are not included in the basic 4000-DRO package.
