Ball Screws for High-Accuracy Machine Tools

Reduced frictional variation when the ball screw reverses direction of motion thereby enabling higher surface finish quality.

All new NSK technology reduces frictional variation when the ball screw reverses direction of motion. This significantly reduces motion errors called quadrant glitches thereby increasing surface finish quality.

Features

1. Stable torque when the ball screw reverses direction nearly eliminates the peak 2 from quadrant glitches.

2. Up to 20% less dynamic frictional torque allows for better correction of the peak 1.

3. Mounting dimensions fully interchangeable with conventional products make for an easy upgrade in existing equipment.

4. Improved surface quality shortens finishing time and saves energy.
