ABSTRACT:
An apparatus and method for removing burrs and other roughage from stamped, milled and cast metallic articles. A conical combustion chamber is provided with a spiral groove which creates a turbulent flow for an ignited combustible mixture, which turbulence transforms the process from combustion to detonation. The detonated gaseous mixture is directed down the conical combustion chamber in expanding fashion to the articles which are to be de-burred, which articles are stored in a receptacle in axial alignment with the conical-shaped combustion chamber. During detonation, the burrs and other roughage are removed from the articles, while the remainder of each article is kept in tact.
