Details: Any Sherline lathe can be ordered with a digital readout installed. Special handwheels with built-in encoders are installed in place of the standard handwheels on the crosslide and leadscrew. These handwheels are connected to a display box that translates handwheel rotation into a readout of table position to within .0005 (or .01 mm). In addition, a constant readout of spindle RPM is displayed. The advantage of a digital readout is that you no longer need to count handwheel rotations when moving distances longer than a single revolution. This helps eliminate math errors. The large, easy-to-read display reads out to 3 and a half decimal places to give accuracy to within .0005. The display for each axis can be reset to zero at any time with the push of a button.
Backlash values can be set for each axis in the programming so that backlash is electronically eliminated when changing the direction of handwheel rotation. A third axis is available on the display box should you later decide to add a vertical milling column or use it on a Sherline 3-axis mill. The readout can function with inch or metric lathes. In the metric mode, the position reads out to 1/100 of a millimeter.
Standard equipment for the lathe includes:

A powerful 90V DC motor with electronic speed controller*
2.75 (70mm) x 6.0 (152mm) crosslide
24 (610mm) steel bed that has 17 (431mm) between centers
Special handwheels are supplied with DRO machines. These handwheels can be reset to zero electronically with the push of a button on the DRO display box. Sherline DRO lathes are outfitted with the special DRO 2 (51mm) handwheels on the leadscrew and crosslide feed screw, and a 2 (51mm) resettable zero handwheel on the tailstock. Each handwheel has laser engraved aluminum handwheel collars
Rocker tool post substituted for the standard tool po
