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.
