PURPOSE:To polish a machined surface very accurately and efficiently by pouring agents such as abrasives into a gap between an electrode and a work after electric discharge machining and controlling the relative positions of the electrode and the work. CONSTITUTION:After electric discharge machining a work 2 with an electrode 1, the electrode 1 and the work 2 after the electric discharge machining are kept set and a greasy viscous fluid 3 mixed with abrasive grains is blown into the gap between the electrode 1 and the work 2 instead of an electric discharge machining liquid. And while moving the electrode in the same movement as the relative motion in the electric discharge machining along a main locus vector (k), a rotation vector (w) is overlapped to the main locus. The rotation vector (w) is rotating at a fast cycle speed about 60-300 cycles per minute and its vector radius is about 1-30mum. |
