Centroid and centroidal deviation of bullets are important design parameters of bullets

and the measurement precise of these parameters is quite necessary to improve production quality and shooting veracity. In order to improve the measuring accuracy and efficiency

this paper presents the working principle and the relevant calculation formulae and measuring equipment for measuring the centroid and centroidal deviation of bullets based on three point method. The main factors affecting precision are discussed

multiple measuring platform with automatic leveling and column structure autorotation of 90°is put forward in the paper. The given experimental results show that these methods can improve greatly measuring precision and efficiency and satisfy the requirement for measuring the centroid and centroidal deviation of bullets with high accuracy. The equipment has wide measurement range

low manufacture cost and broad appliance and development prospect.
