A CNC machine tool for preparing high-precision graphite screws relates to the field of graphite threaded rod preparation equipment. It includes a transfer mechanism, a feeding mechanism, and an automatic grinding mechanism. The transfer mechanism includes a motor-driven transfer wheel. The feeding mechanism includes an inlet end for receiving graphite rods and a delivery fixing end for feeding the graphite rods to the automatic grinding mechanism. The delivery fixing end includes an openable and closable delivery fixing lip. The automatic grinding mechanism includes a worktable that can move closer to or further away from the delivery fixing end. The worktable is equipped with a rod-turning device that can reciprocate horizontally in the left-right direction of the delivery fixing lip. The rod-turning device includes a positioning arm and a grinding arm. The grinding arm has a rod-receiving mechanism on the side away from the positioning arm. The rod-receiving mechanism includes a receiving part and a collecting part. This invention has a high degree of automation and can mechanically pick up the graphite rods.
