Case Study: Reducing Costs in Automotive Machining Center
Technical Challenge
A worldwide manufacturer of automotive components was experiencing significant unplanned downtime due to the failure of the ball screws in their machining center. This had a major effect on manufacturing output, resulting in increased costs and reduced machine reliability.
NSK Ball Screw with High-Performance x1 Seal Design
NSK Solution
NSK analyzed three of the failed ball screws to determinate the main reason for the failures, and developed a special design that improved the performance characteristics, especially the high-performance sealing design. Reduced machine downtime and a substantive increase in ball screw life achieved a cost savings of $284,365.
