IPC: B23H1/02
Filed: 2003-03-17
Abstract: <P>PROBLEM TO BE SOLVED: To improve the machining speed while keeping the finishing quality of the surface of a workpiece.  <P>SOLUTION: This electric discharge pulse power device is used for an electric discharge machine in which an electric discharge pulse is generated between the workpiece 1 and a discharge electrode 5 disposed at a space from the workpiece, thereby machining the surface of the workpiece. A transistor TN is a switching element put in the off-state at least during a part of the period in applying a discharge pulse. A charge for a discharge pulse is stored in a capacitor C through the transistor TN. Since the switching element becomes an off-state, there is no fear of extension of discharge time and increase in an electric current of the discharge electrode 5. Accordingly, the charge current is increased to shorten the charging time of the capacitor C so that the machining time can be reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
