A bilateral automatic machine for machining the edges of plates of glass, stone-like and of other plate shaped materials and the like, comprising a supporting frame (1) which has a conveyor (2) for the plates (3) to be machined. There are also provided an abutment shoulder (5) and a movable shoulder (6) for supporting abrasive grinding wheels (10a,10b,10c) which act on the opposite edges of the plates (3). The machine comprises, for each shoulder (5,6), downstream of the last grinding wheel (10a,10b,10c) in the direction of advancement of the plates (3), a sensor (30) for detecting the dimensions of the plates (3) being machined which drives an advancement device (AD.M.) for the advancement of the last grinding wheel. Each grinding wheel (10a,10b,10c) except for the first grinding wheel (10a) along the advancement direction of the plates (3) is provided with a detector (D.M.) for detecting the energy absorbed by the corresponding motor (M) and an actuator (A.M.) for actuating the advancement device (AD.M.) of the grinding wheel that is located immediately upstream as the energy absorbed by the grinding wheel located immediately downstream of it increases. <IMAGE> |
