The main function of ball & acme screw assemblies is to provide a drive mechanism, usually within a positioning table, to move a load. The drive mechanism is an element that contributes to position accuracy, repeatability, speed, and mechanical system resolution. This results in low wear and long life. Key Features of a Ball Screw System are:
- Rolled Ball Screw system utilizes a tapped nut with a standard accuracy grade rolled screw.
- Precision Rolled Ball Screw system utilizes a ground nut with a higher accuracy grade rolled screw.
- Ground Ball Screw system utilizes a ground nut with a high accuracy precision ground screw, and provides the highest performance and accuracy.
