Application of the Electrical Discharge Truing Technique on the Lapping Machining Process

This paper discussed the principle about the Electrical Discharge Truing(EDT) technique ,which applied in lapping machining process, including EDT status with different environment and machining conditions, and an EDT equipment on a lapping machine have been developed and used in the experiment of EDT. Then some experiments were carried out for verifying of the EDT effect with different EDT parameters such as electric voltage, EDT gap, and the EDT media. Finally, the efficient and precision EDT was achieved with the suitable EDT parameters.
