The utility model relates to a metal bar fatigue specimen polishing device. The metal bar fatigue specimen polishing device comprises an upper cover 1, a clamping and rotating system 2, a polishing system 3, a support 4 and a grinding fluid spraying system 5. The clamping rotating system 2 fixes a sample 26, the stepping motor 23 adjusts the sample 26 to rotate intermittently, the grinding system 3 is fixed to the support 4, and the speed regulation electric grinding machine 32 drives the flexible grinding head 31 to grind in the axial direction of the sample 26 under the supporting effect of the adjusting supporting rod 33. Grinding fluid is sprayed to the surface of the sample 26 through the grinding fluid spraying system 5 to achieve the functions of improving the grinding efficiency and reducing the temperature of the sample, the bottom of the support 4 is an inclined face, and the grinding fluid can be collected. The metal bar fatigue specimen polishing device is high in automation degree, the polishing
