Driveshaft & Ball Screw Measurement

Precision Measurement for Driveshafts and Ball Screws

Application Background

Ball screw accuracy directly impacts power transmission, machining precision, and equipment lifespan. Traditionally, only a few dimensions were sampled in the lab using length gauges. Likewise, worm shafts in reducers are typically inspected with contact-type gear testers—time-consuming, operator-dependent, and limited in accuracy. As precision and efficiency demands increase, manufacturers need inline, high-accuracy, automated solutions to ensure consistent quality and improve yield.

Common Challenges

• Long, slender parts deform easily during manual measurement
• Complex features like threads require multiple tools and setups
• Lab-based inspection disrupts production flow
• Manual operations and records risk data loss and traceability gaps
