The machine (10) has a coffee mill driven by an electric motor (14) and a measuring and counting circuit (22). the circuit (22) counts pulses which are proportional to the number of rotations of the coffee mill (28) and then controls stopping of the motor when a predetermined number of pulses have been counted. The measuring circuit (22) has a detector (20) which emits a counting pulse after each rotation of an element attached to the coffee mill (11). This element is connected to the mill's grinder (13).
