[0005] The working principle of the utility model is as follows: The barrel body of the piston cylinder to be polished is fixed through the clamping mechanism. Then, the polishing member is placed into the piston cylinder to a specified length through the push rod motor, and the end of the cylinder is positioned and fixed through the positioning member. After that, the rotating motor is started to control the polishing member to rotate, and the inner wall of the piston cylinder is polished through the abrasive discs. The debris generated during polishing is collected through the gaps between the abrasive discs.
