As high-precision transmission components, measuring the surface topography of ball screws is not only essential for quality control but also critical for preventing failures and extending product lifespan. In practical applications, excessive surface roughness increases friction, leading to temperature rise and wear, while waviness can cause vibration and noise. Additionally, the accuracy of the raceway geometry—such as the radius of curvature and contact angle—affects load distribution and mot
