Depending on their specific condition, ball screws are often repairable. Certain issues, including loss of repeatability can be solved through regrinding the grooves of the ball thread and subsequently using larger balls in the entire assembly. If a ball sustains minor damage, it can generally be straightened and returned to service with its original intended accuracy. Ball screw repair can also fix problems such as chipping, brinelling, spalling, and feathering through re-plating and regrinding. At Comptrol, we provide these range of repair services for ball screws.
