Microtube Electrode System for Electrolytic Cutting of Large Thickness Workpiece Method

Abstract

The invention relates to a method and device for performing electrolytic cutting on a large-thickness workpiece by using a micro tube electrode, and belongs to the technical field of electrochemical machining. The method is mainly characterized in that a micro hollow metal tube with grouped holes or grouped seams or a hollow non-metal tube with a conductive coating is selected to replace an existing metal-wire-shaped electrode to cut the large-thickness workpiece; structures of the grouped holes or the grouped seams are formed in the micro tube electrode with one closed end, an electrolyte with certain pressure is injected from one end of the micro tube electrode and is jetted out from the grouped holes or the grouped seams, the fresh electrolyte flowing at a high speed can directly reacha machining area to perform etching cutting on the workpiece, and electrolysate and bubbles in micro cut seams can be rapidly washed away; and in the machining process, a servo motor drives the microtube electrode to rotate through a steering device so as to change the jetting direction of the electrolyte, and meanwhile, the relative movement of the micro tube electrode to the workpiece can be controlled by utilizing the movement of a numerical control machine tool workbench, so that steering cutting of the workpiece can be realized. The method and the device have the advantages that the update rate of the electrolyte in machining clearances can be increased, the electrolytic reaction speed can be increased, the electrolytic cutting stability can be improved, and meanwhile the electrolytic cutting capacity of the large-thickness workpiece can be improved.
