The invention provides a turning, 
grinding and 
polishing all-in-one 
machine device for a rubber roller. By the adoption of the turning, 
grinding and 
polishing all-in-one 
machine device for the rubber roller, turning, 
grinding through a 
grinding wheel and 
polishing through an 
abrasive belt can be achieved at the same time. According to the turning, grinding and polishing all-in-one 
machine device for the rubber roller, a turning machine, a grinding machine and a polishing device for the rubber roller are highly integrated, and new functions are additionally achieved based on the grinding machine special for the rubber roller. A power machine head used for making a workpiece rotate is installed at one end of a machine body, and a machine 
tail is installed at the other end of the machine body; a spindle is arranged on the machine head; one end of the spindle is connected with a chuck, and the other end of the spindle is connected with a power device; a center used for fixing the workpiece is arranged on the machine 
tail, and the spindle of the machine head and the center of the machine 
tail are located on the same center line; a 
measurement device is installed on the upper surface of the machine body; and an annular 
abrasive belt driving and tensioning device is installed on a 
workbench. A whole annular 
abrasive belt can rotate around the axis of a driving wheel, so that the 
contact angle between the abrasive belt and the workpiece is changed, and accordingly the position, making contact with the workpiece, of the abrasive belt is changed, and different 
machining requirements are met.
