Sherline Model 4000-DRO 3.5" X 8" Lathe with factory installed DRO

This Sherline lathe with the digital readout installed has special hand-wheels with built-in encoders which are installed in place of the standard handwheels on the crosslide and leadscrew. These hand-wheels are connected to a display box that translates hand-wheel 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 hand-wheel 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 hand-wheel 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 hand-wheel is attached.

Standard equipment for the lathe includes:
 

A powerful 90V DC motor with electronic speed controller*

2.75″ (70mm) x 6.0″ (152mm) crosslide

15″ (381mm) steel bed to allow 8″ (203mm) between centers

Special hand-wheels are supplied with DRO machines. These hand-wheels can be reset to zero electronically with the push of a button on the DRO display box. Sherline DRO
