Electrochemical deburring system using electroplated cbn wheels

Abstract

Deburring and edge finishing technology as the final process of machining operation is required for manufacturing of advanced precise components. Fitting a deburring process into FMS (flexible manufacturing system) with high efficiency and full automation is a difficult problem. There is no standardized procedure for the removal of burrs of various shapes, dimensions and properties and currently manual methods are used. In particular, deburring of internal cross holes which are perpendicular to a main hole is more difficult and the electrochemical method is a potential solution. Therefore, it is needed to develop the electrochemical deburring technology for internal deburring in a cross hole shape. In this study, the mechanism of electrochemical deburring by using electroplated cubic boron nitride (CBN) wheels is described and its deburring performance is investigated in an internal cross hole. Also, deburring efficiency for internal cross holes is examined with electrolytic currents and other electrochemical conditions. The optimum range of deburring the internal cross hole corresponding to the acquired edge quality is determined. (C) 1997 Elsevier Science Ltd.
