ELECTROLYTIC DEBURRING DEVICE, ELECTROLYTIC DEBURRING METHOD AND ELECTRODE

摘要

PURPOSE:To uniformly and speedily carry out removal of burr grown at an intersection part of a plural number of holes by improving an electrolytic machining precision and a electrolytic machining speed by means of relatively oscillating a machined article in the shaft direction of an electrode. CONSTITUTION:At the time of removing burr grown at an intersection part of a plural number of holes provided on an machined article, a bar type electrode 2 is inserted in one of the holes selected from a plural number of holes holding the machined article 4. Additionally, voltage is applied so that this electrode 2 comes to be a negative electrode and the machined article 4 comes to be a positive electrode respectively. Electrolytic deburring is carried out by way of adding mechanical oscillation to the electrode 2 inserted into the hole of this machined article 4 into which this electrode 2 is inserted in the shaft direction of the electrode 2.
