“Significant breakthroughs have been made in the field of normal cross-section detection of ball screw raceway. The expert team has established a ball screw raceway normal section measurement system based on optical micrometers. By designing a detection device and optimizing data processing algorithms, fast, accurate, and non-destructive testing of the normal section of the ball screw raceway has been achieved. This system not only improves detection accuracy, but also significantly enhances the stability and reliability of measurement results. Experimental verification shows that compared with the data provided by the manufacturer, the error of the normal cross-section parameters measured by the optimized detection system is significantly reduced, and the improvement rate is significant. This research achievement provides a powerful tool for accurate measurement of the normal cross-section of ball screw raceway, which is of great significance for improving product quality and promoting technological progress in related fields.”
