Any Sherline lathe can be ordered ready for the application of stepper motors and Computer Numeric Control (CNC). Sherline installs stepper motor mounts in place of the leadscrew and crosslide handwheels. These mounts are designed to accept 23-frame size stepper motors. A dampened coupling for the 1/4″ motor shaft is included. The coupling drives the leadscrew through two 3/8″ bearings with adjustable preload to remove end play.
Once you have the machine, you will need to attach stepper motors and connect them through a driver to a computer. Several aftermarket companies provide the proper motors, drivers and software to complete the package. You can read a list of these supplies and visit their web sites for price comparisons by visiting the CNC Dealers page within Sherline’s site. Sherline also offers high quality stepper motors, which can be found in the accessories section of this site.
