去毛刺和精加工技术是制造先进精密零件的最后一道加工工序。在柔性制造系统中实现高效、全自动化的去毛刺加工是一个难题。对于各种形状、尺寸和性质的毛刺的去除没有标准化的程序，目前使用的是手工方法。特别是，垂直于主孔的内部交叉孔的去毛刺比较困难，电化学方法是一种潜在的解决方案。因此，有必要开发用于十字孔形状内部去毛刺的电化学去毛刺技术。本文研究了电镀立方氮化硼（CBN）砂轮的电化学去毛刺机理，并对其内部交叉孔的去毛刺性能进行了研究。此外，在电解电流和其他电化学条件下，考察了内部交叉孔的去毛刺效率。确定了与所获得的边缘质量相对应的内交叉孔去毛刺的最佳范围。
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.
