💡 What is a ball screw kit used for in CNC machines?

Ball screw kits handy transform rotary motion into precise linear motion for accurate tool positioning.

- handy for precise positioning and repeatability - reduces backlash for smooth linear moves - supports vertical mounting with high static/dynamic stiffness - lowers friction, heat, and drive power for CNC setups
