Aiming at the improved high-speed bullet assembling line with a rotary structure; a new high speed rotation-type bullet providing method is proposed. Rotation-type bullet providing machine is time-sharing controlled by sampling the bullet qualities, and the feedback of the position of cartridge case signal makes sure the synchronization and match control between air cylinder bullet providing system and cartridge case provisions. The results prove that the high-speed continuous bullet providing system can reach the speed of 240/s; greatly improves the manufacture efficiency of small-caliber bullet; and steady running speed can reach 180~200/s.
