Abstract
Deburring of metal articles and parts in a combustion chamber process is accomplished in a machine requiring only a short stroke to open and close the combustion chamber in the processing of a series of articles or parts. Only the cap plate of the combustion chamber is fixed to the upper part of the vertical frame of the machine, it being provided with the inlet for the combustion gases, and the hollow cylinder and bottom plate form a mating unit of the combustion chamber, of which a number may be provided for sequential operation, which may travel into the work position and out of it on conveyor rails. Compression to seal the parts of the combustion chamber together during combustion processing is provided by a hydraulic or pneumatic piston drive mounted on the bottom portion of the frame to bear against the bottom plate of the particular interchangeable combustion chamber unit that is located in the work position.
