“CNC-Ready” machines are not turn-key machines. And cannot be used until stepper motors have been installed
All machines that are described as “CNC-ready” have Stepper Motor Mounts, but do NOT include Stepper Motors, Linux computer & software, or CNC software.
The MASSO G3 CNC controller, power supply, stepper motors, cable system and optical encoder are sold as a part of our Accu-Pro line of machines and are not available for purchase separately or as an upgrade option to existing machines.
See our CNC Machining FAQs page for answers to the most common CNC questions.










17″ CNC-Ready Lathe
The Sherline 17" CNC Lathe is a precision benchtop machine designed for small, detailed, and accurate turning applications. Built on Sherline’s proven 3.5" x 17" (90 mm x 430 mm) lathe platform, this CNC-ready version includes factory-installed stepper motor mounts on both the X and Z axes - allowing you to add your own stepper motors and controller for complete CNC control.
With a 17" long bed, 8" crosslide, and a working diameter capacity of up to 3.5" over the bed, this lathe provides the versatility needed for prototyping, small-part production, model engineering, R&D, and teaching environments. The rigid aluminum/steel construction, dovetail slides, and adjustable backlash compensation ensure repeatable accuracy on even the smallest parts.
All CNC-ready Sherline lathes include the same high-quality headstock, spindle, and bearings used in our manual models, giving you excellent spindle concentricity for demanding turning operations. The machine still allows for full manual operation when needed - simply turn the handwheels for quick setup or manual machining tasks.
Features:
- CNC-ready with factory-installed stepper motor mounts (X and Z axes)
- Turns parts up to 3.5″ (90 mm) diameter over the bed
- 17″ (430 mm) bed provides extended travel for longer workpieces
- 8″ (200 mm) crosslide for increased tool reach
- Precision-machined dovetail slides with adjustable gibs and backlash
- High-accuracy spindle and headstock used across all Sherline lathes
- Manual control possible with included handwheels
- Compatible with Sherline’s full line of accessories
- Made in the USA
Ideal Applications:
- Model making and miniatures
- Prototyping and custom part production
- Educational CNC training programs
- Hobbyist and light industrial use
Note: This is a CNC-ready lathe. Stepper motors and CNC controller are sold separately. For a fully assembled and tested system, see our complete CNC lathes.
