The invention relates to the technical field of abrasive and grinding tool equipment, and discloses an abrasive grinding tool convenient to polish. The abrasive grinding tool comprises a supporting plate, a guide groove is formed in one side of the top of the supporting plate, and a guide block is slidably connected with the guide groove, one end of the guide block penetrates through and extends to the outside of the guide groove and is fixedly connected with the bottom of a motor base, the top of the motor base is fixedly provided with a driving motor, one end of the output shaft of the driving motor is connected with a coupler in a clamped mode, a transmission shaft is connected with one end, far away from the driving motor, of the coupler in a clamped mode; and a grinding wheel piece isfixedly connected with one end, far away from the coupler, of the transmission shaft. The abrasive grinding tool convenient to polish is characterized in that the guide block, the driving motor and the grinding wheel piece are cooperated to use, so that mechanical parts can be machined by translation of the driving motor; and the situation that the machining error occurs due to the fact that handshakes during hand-held machining is avoided, the machining quality of the mechanical parts is improved, and the rejection rate is reduced.
