Sherline 4400-DRO/4410-DRO- 17" Lathe with Factory Installed Digital Readout (DRO)

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 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. (NOTE: The unit does not translate dimensions from inch to metric. It must be initialized to work with the pitch of the leadscrew to which the handwheel is attached.)
