The working principle and the using process of the invention are as follows:

preparing brake discs of the same type to be polished in the prior art;

before the brake disc needing to be polished is installed, the electromagnet 20 is turned on to attract the first magnet 19, so that the extrusion plate 17 is horizontally attached to the extrusion rod 16, and the extrusion plate 17 is further rotatably accommodated in the notch 14 in the first rotating shaft 7;

the electric push rod I28 is opened to push the sliding plate 27 to move upwards, so that the lifting column 31 and the polishing disc 33 move upwards, the polishing disc 33 moves upwards to be far away from the rotating shaft I7, a brake disc is placed conveniently, and the sliding plate 27 slides more stably under the action of the sliding column I29;
