The device, which serves for processing, particularly for cutting and diffusing at least one product, particularly a food product, includes at least one blade that is connectable via at least one coupling member and an energy converter to an ultrasound source and that is fastened to a blade holder, which is connected to a drive device that is held by a framework. According to the invention the drive device includes a plurality of actuators, which are connected each on one side via a first rotary joint to the blade holder and on another side via a second rotary joint in such a way to the framework that the blade holder is held by the actuators alone and is displaceable and optionally turnable within a volume of operation.
