The machine has an output shaft (12) for driving a cutting tool in motion and is connected to first and second motors by a transmission with rotationally driving ring (18) and tapped drive nut (27). The transmission has a transmission assembly with an epicyclic train that comprising pinions (14-17) attached to diving ring and nut. A reduction ratio of epicyclic train and reduction ratio between pinions are determined such that the difference between rotation frequency of nut and ring is equal to the product of rotation frequency of second motor and a constant. |
