Abstract (en)

[origin: WO2016120393A1] A device and a method for cleaning fractured surfaces of fractured or cracked workpieces (6, 8), for example a bearing seat of connecting rods, crankshaft housings or Cardan shafts, are proposed. In this case, the two parts (6, 8) which have the fractured surfaces (10) are positioned such that the respectively associated fractured surfaces (10) are in contact or are spaced apart from one another. Then, the two parts are set into vibration with respect to one another in a direction along the fractured surfaces (10), wherein a ram (26, 38) is directed circumferentially against the first part (6) and/or the second part (8), wherein the impulses or impacts are/is introducible circumferentially into the first part (6) and/or the second part (8).
