ABSTRACT:
The disclosure of this invention pertains to the method of removing burrs from an electrically conductive article by exposing the article to a plasma flame wherein the parameters of the plasma are so chosen that the plasma becomes concentrated at the burrs and the consequent concentration of heat in the burrs causes the burrs to vaporize or otherwise diminish. The disclosure also pertains to apparatus for supporting the article and moving relative to the flame for a deburring operation.
