A machine for processing food products, includes a processing tool oscillatingly driven by a motor and a drive train, and a trigger system which, in each cycle of oscillating movement of the processing tool, triggers a predetermined action of the machine at a predetermined timing, the trigger system including a signal generator arranged in the drive train to deliver a reference time signal in each cycle, a timer measuring a time passed since the last occurrence of the reference time signal, and an electronic control device storing a displacement/time curve of the processing tool for at least one processing speed of the machine and in which a position of the processing tool is programmable at which the action shall be triggered, the control device determining on the basis of the displacement/time curve, the trigger timing corresponding to that position and triggering the action when the timer reaches this timing.
