6844-Series Ball Screw Benchtop Lathe with High-Torque Stepper Motors
Complete Ball Screw Benchtop Lathes

Our new ball screw lathes are based on our popular 17″ 4400-series benchtop lathe and are available with an assortment of accessories. The ball screw benchtop lathe was designed with the ball screws directly under the lathe bed and crosslide to help avoid chip contamination and give direct in-line feed from the ball screw. You can order it as CNC-ready if you already have #23 NEMA frame stepper motors, or you can order it with our high-torque stepper motors. Low friction in ball screws yields high mechanical efficiency compared to other leadscrew alternatives, and efficiencies can range from 70% to 95%.

The essential upgrade parts for the ball screw benchtop lathe include the ball leadscrews, a solid aluminum base, stepper motor high-torque couplings, the ball screw lathe saddle, an 8″ crosslide, and optional limit switches on each axis.

NOTE: Ball screw lathes come in metric calibrations only
