💡 What is a lead screw used for in CNC machines?

Lead screws convert rotary motion to precise linear travel, enabling accurate axis positioning.

- Provides controlled, smooth motion along an axis
- Works with a matching nut to convert rotation into linear displacement
- Common in CNC and 3D printer Z-axis applications for precise positioning
