Abstract: When bodies such as connecting rods, bearings, ring-shaped housings or similar are separated by breaking, material particles are torn out of the broken surface. These particles initially continue to adhere to the broken surface at first, before becoming detached from the broken surface and falling out when a force is exerted subsequently. According to the invention, the bodies are subjected to a vibration treatment after they have been separated by breaking in order to prevent detachable adhering particles of the material from falling out in an uncontrolled manner.
