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 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.

- WW Collet Adapter*
- Drawbar & 3/8" Knockout Bar
- Set of 5 Collets: Inch set: 1/16", 1/8", 3/16", 1/4", and 5/16" Metric set: 2.0 mm, 3.0 mm, 4.0 mm, 5.0 mm, and 6.0 mm
WW Collet Sets
Collets provide a quick, easy method of mounting cylindrical parts or bar stock in the lathe with a great deal of centering accuracy. Each collet is actually a small, precision 3-jaw chuck that fits into a special tapered adapter in the headstock. A drawbar that passes through the headstock and threads into the backside of the collet is used to draw the collet up into the tapered adapter. The adapter causes the jaws of the collet to close down, gripping the part to be machined. Typically, collets provide a very accurate part mounting system, but each size collet can accommodate only a small range of diameters of approximately ±.001" (.02mm).
WW collets differ from milling collets in that they have a hole all the way through the collet and drawbar. The maximum diameter stock that can pass entirely through the collet is 3/16" or 4.5mm. The WW collets that are larger than this diameter are sometimes referred to as "pot" chucks.The Sherline WW collet set includes a WW style collet taper adapter, a drawbar, and a set of five WW collets. These collets are manufactured by Sherline and are built to standard WW specifications; however, we have come across collets that are called WW and will not fit our drawbar and adapter. Be sure to check WW collets made by other manufacturers to be sure they fit our adapter before you purchase them. Sherline manufactures a slightly larger .315" adapter and drawbar set that will accommodate some of these other brands.
Collet AccuracyThese collets have a maximum runout of .002" or less. If the WW collet adapter is trued in as suggested in the instructions, it will run dead true. This will allow the collet runout to be at its best. Collet sizes above 3/16" (4.5mm), considered pot chucks, are not bored through. They are only bored .260" deep and depending on your setup and length of the part, you may experience greater runout further away from the front of the collet.
5-piece collet set includes:Other Collet Sets
Sherline also offers sets that include a wider selection of collets. It includes 17-inch size collets from 1/16 to 5/16", while the metric set includes 14 metric collets from 1.5 mm to 8.0 mm. These sets come in an oak box with a divider that has extra holes for more collets should you add them later. It also includes a drawbar, a collet adapter, knockout bar, two collet pot chucks, and a collet blank.
The largest set we offer includes 78 collets from 0.3 mm to 8.0 mm by 0.1 mm increments. This comes in an oak box with 96 holes in case you add some inch sizes but does not include the adapter, drawbar or other accessory items in the sets described above.
