💡 What is a ball screw used for in CNC machines and why pick a high lead style?
In short, ball screws convert rotary motion into precise linear travel with low friction, delivering fast, smooth axis moves.
- Ball screws provide accurate positioning with low backlash for reliable repeats
- High lead design boosts rapid travel while maintaining stiffness
- Ideal for milling, routing, and automated assembly lines requiring long, precise travel
