The centroid and centroidal deviation of bullets are important design parameters of bullets, In order to improve the measuring accuracy and efficiency, a high accuracy inspecting system for measuring the centroid and centroidal deviation of bullets based on three point method is designed. The working principle, relevant calculation formulae and the measuring equipment for measuring the centroid and centroidal deviation of bullets are presented, and the main factors affecting measuring precision are discussed. Then,a multiple measuring platform with automatic leveling and column structure autorotation of 90°is put forward. The given experimental results indicate that the measuring precision of the centroid and the centroidal deviation is no more than 0.1 mm and 0.01 mm respectively, which satisfies the qualification needs for high accuracy measuring the centroid and centroidal deviation of bullets. The system has wide measurement ranges, low manufacture costs and broad application and development prospects.
