Beschreibung
Zusammenfassung:	The utility model provides a polishing device which comprises a driving mechanism, a fixing mechanism and a polishing mechanism. The driving mechanism is connected with the fixing mechanism and is used for driving the fixing mechanism to rotate according to a preset rotating speed; the grinding mechanism comprises a moving unit and a polishing unit which are connected with each other; the moving unit can drive the polishing unit to do linear motion and rotary motion relative to the fixing mechanism. The polishing unit comprises an abrasive belt, a first abrasive belt winding disc, a second abrasive belt winding disc, a grinding head and a driving unit; one end of the abrasive belt is wound on the second abrasive belt winding disc, and the other end of the abrasive belt is wound on the first abrasive belt winding disc through the grinding head; the driving unit is used for automatically winding the abrasive belt of which the polishing times exceed a set threshold value onto the first abrasive belt winding disc
