The ball screw lathe design is a reimagined version of our popular 17″ 4400-series 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, 36V closed-loop stepper motors with #23 NEMA frames, motor mounts with high-torque couplings, and C5 bearings in the headstock for smoother spindle operation.
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.
