A grinding machine comprises a frame having a rotary casing that bears rotary holders for grinding discs, as well as a drive motor which is mounted on the frame and interacts with the casing and the holders to drive the machine. The drive motor is connected by means of a continuous flexible or articulated element to the holders for driving the latter in the direction of rotation, wherein at least one of the holders is coupled to the frame by means of a gear transmission, in order to bring the casing into rotation when said holder is driven. |
