Polishing equipment for aluminum bar machining

The utility model discloses polishing equipment for aluminum bar machining, which comprises a device shell, a device top cover is arranged at the upper end of the device shell, a moving mechanism is arranged at the upper end of the device top cover, and polishing mechanisms are arranged at the lower end of the moving mechanism and located on the two sides of the bottom end of the inner wall of the device top cover. The upper and lower ends of the front end face of the device shell are provided with a device cover door and a material receiving box correspondingly. Through the rotary threaded rod at the upper end of the fixing base, the fixing blocks in the movable grooves in the two ends of the fixing base move relatively, aluminum bars of different sizes are rapidly clamped, the applicability of the device is improved, a closed structure is formed inwards through the device cover door and the device shell, and the practicability is high. The waste generated during machining is prevented from flying in the air
