When the polishing machine is used specifically, firstly, a user needs to start the belt driving motor 43, the belt driving roller 42 drives the thick and thin double-sided polishing belt 44 to move at a high speed, and the surface roughness of the belt driving roller 42 is large, the friction force with the thick and thin double-sided polishing belt 44 is large, and the contact area is also large, so that the thick and thin double-sided polishing belt 44 can be driven to move at a high speed, and the thick and thin double-sided polishing belt 44 moves at a high speed and displaces with the surface of a polished workpiece 55, so that the polished workpiece 55 is polished;

in the polishing stage, the workpiece rotating motor 56 is started at the same time, the clamping device 54 drives the polished workpiece 55 to slowly rotate, the rough surface of the rough and fine double-sided polishing belt 44 is in contact with the polished workpiece 55, and the surface of the polished workpiece 55 can be kept in a uniform and relatively rough state under the condition of removing the large concave-convex characteristics of the surface through polishing, so that the polished workpiece 55 can be combined with a paint surface;

in the polishing process, the manual push-pull handle 53 is pushed to and fro slowly until the surface of the polished workpiece 55 is in an even and relatively rough state, the L-shaped sliding limiting plate 50 is pushed to the extreme position of the end part at the moment, so that the thick and thin double-sided polishing belt 44 is separated from the polished workpiece 55 and wrapped on the clamping device 54, and the polishing process can be finished by turning off the belt driving motor 43 at the moment;

while the workpiece 55 to be polished rotates slowly, the slidable spray head 58 sprays the surface of the workpiece 55 to be polished layer by layer for multiple times, and the sprayed area of the workpiece 55 to be polished continues to rotate upwards immediately after being sprayed with the paint, so that the problem that the liquid paint naturally flows before solidifying can be greatly avoided;
