The ball screw lathe design is a reimagined version of our popular 17″, 4400-series benchtop lathe. The lathe has a new solid aluminum base, which creates a very rigid assembly, a beefed-up saddle to accommodate the ball screws, a larger 8″ crosslide, and #23 NEMA frame stepper-motor mounts with high-torque couplings.
Ball Leadscrew Specifications
- Rolled Ball Screw with BSH Nut
- 10mm Diameter, 2mm Lead
- C7 Accuracy*, P1 Preload
*C7 accuracy has a linear tolerance of 50 micrometers / 300mm or .002″ / 12.0″.
The ball screws are only available in metric, so the numeric graduations on the handwheel dials are 2mm per revolution and .02mm per line.
Connecting your CNC-Ready Lathe to a Controller
Once you have the machine, you will need to attach stepper motors, a CNC driver, and a CNC controller. Sherline offers the following options to connect your ball screw lathe to a CNC controller:
- Stepper motors–High-torque (P/N 67126, recommended) or standard (P/N 67127)
- 4-axis Driver Box (P/N 8760)
- Acorn CNC controllers (P/N 9400) or Linux CNC computer (P/N 8761)*
*NOTE: The Linux PC includes a mouse and keyboard (a monitor is not included). However, you must provide your own computer for the Acorn Controller.
Ordering options:
Use the selections in the drop-down menus above to configure your machine. The Machine Accessories tab above provides more specifications on each option and accessory package.
- A powerful 90V DC motor with electronic speed controller*
- Standard headstock: #1 Morse taper with 3/4 x 16 external spindle thread (Option to upgrade headstock above)
- The base is a solid 28″ x 5″ x 1/2″ 6061 aluminum plate, and the headstock and tailstock mounts are solid, machined 6061 aluminum.
- The lathe saddle is hard anodized for long wear, and internal oiling ports are incorporated to keep the lathe bed dovetail areas lubricated.
- 2.75″ (70 mm) x 8.0″ (203 mm) crosslide
- 24″ (711 mm) steel bed that has 17″ (431 mm) between centers
- 2.5″ (63 mm) zero-adjustable handwheel for the leadscrew, one 2″ (51 mm) zero-adjustable handwheel for the crosslide feed screw, and a 2″ (51mm) zero-adjustable handwheel on the tailstock. Each handwheel has laser-engraved aluminum handwheel collars**
- A 3/8″ Insert Holder Tool Post (P/N 7600) with a 55° RH Tool Holder w/Carbide Insert(P/N 2256)
- Pulleys, drive belt, faceplate, lathe dog, two dead centers, three hexagonal keys, eight-foot three-wire power cord, and instruction manual
- Optional limit switches***
* Not included with a lathe ordered without motor and speed control.
**CNC-ready machines cannot be operated manually unless double-shaft stepper motors are installed.
***The limit switches were designed to work with our Sherline/MASSO G2 CNC Controller, but you can connect them to any controller that is configured to work with our limit switches, such as Acorn, Mach 3, Mach 4, etc. See the related products below on the limit switch product page.
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.
