Ball Screw

High Flexibility in Application
Although the continuous load in the high-speed range is comparatively low, very high short-term peak loads also act on the ball screw during the temporary change of the high accelerations or decelerations as well. So that the balls can roll without slipping and precisely in all operation phases, the preload and therefore the detachment force may need to be modified accordingly.

Application Areas
In addition to high-speed main spindles, machine tools, such as machining centers for high-speed cutting applications, require very dynamic feed axes to be able to produce highly precise workpieces in short cycle times. The high travel speeds minimize the non-productive times and allow for optimal machining processes. With the high dynamics of such feed axes, however, not only is the focus on the axial travel speed, but rather especially on a high acceleration and a high deceleration.

High-speed ball screws are used for extremely dynamic requirements. That is why they are designed to achieve extremely high travel speeds, especially for very high pitches. For this purpose, they effortlessly handle high-speed acceleration and deceleration, peak loads and also severe jerks.
