Title: Electric discharge machining of roll-shaped work
Inventor: KAWANO MITSUGI
IPC: B23H9/04
Filed: 1983-12-26
Abstract: PURPOSE:To make it possible to obtain a uniform satin surface even when there is an unstable machining or short-circuiting during the machining process by adjusting the feed speed of electrode to the moving speed of a column in the electric discharge machining method of a roll for cold rolling of a steel band. CONSTITUTION:Based on the measured value of a measuring instrument 16, which is used to measure the feed rate of electrode per unit time during the electric discharge machining of a roll for cold rolling, the feed speed of head columns 9, 9' is controlled by a column traverse-feed drive unit 7. The column traverse-feed drive unit 7 feeds the head columns 9, 9' based of the detected feed rate per unit time of electrodes 11, 11'. At this time, when an unstable machining or short-circuiting should occur, a current flows between the electrodes, but the machining process ceases to progress, and the feed rate of the electrodes 11, 11' remains unchanged in its value and the feed rate per unit time, namely the feed speed of electrode, becomes zero. In this way, the feeding of the head columns 9, 9' by the column traverse-feed drive unit 7 stops.
