講演内容 An electrode feeding device for micro-hole electrical discharge machining by using AZARASHI mechanism is described in this paper. This device consists of a controlled friction device, a friction device applying a constant friction and an extension device to change the distance between the friction devices. For easy friction adjustment, the displacement of a stacked piezoelectric actuator was magnified in the controlled friction device, and the constant friction was applied with a coil spring. The relationship between the feeding velocity of an electrode with a diameter of 0.2 mm and driving frequency was measured. Then performance of electrical discharge machining with a capacitance discharge circuit was measured. Because this device responds quickly, a high cut-off frequency of a low pass filter was usable.
