Mill Ball Screw XYZ-Axes Retrofit Kit
The Mill Ball Screw XYZ‑Axes Retrofit Kit is a retrofit upgrade for Sherline milling machines that replaces the standard X and Y axis lead screws with precision ball screws to reduce backlash and improve smooth, accurate motion. It includes rolled ball leadscrews with BSH nuts (10 mm × 2 mm lead, C7 accuracy), high-torque stepper-motor couplings and mounts, and ball screw mill saddles assembled at the factory for easy installation.
Why it matters:
- Better positional accuracy and smoother CNC motion on the X and Y axes
- Fully assembled components ready to install
- Works with high-torque stepper motors for improved performance
