YOU SAVE $45.00 over the price of these items purchased individually. Sherline Lathe (Metric)-For years, Sherline lathes have been retrofitted by various companies to add CNC controls. Rather than providing different hole patterns and mounts for each company, Sherline has now standardized the CNC mount by introducing their own design. All accessories and handwheels that would normally come with that machine are included, but they are configured with stepper motor mounts on the crosslide and leadscrew, ready for your stepper motor and controls. The mounts feature a superior flexible coupler that is connected to the leadscrew through two ball bearings that are preloaded to eliminate play.
