Description

technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to an electrolytic machining device with a porous structure with variable apertures. Background technique [0002] In electrolytic machining, the size of the tool electrode machining aperture is usually controlled by controlling the magnitude of the pulse voltage. When it is necessary to expand the processing aperture of the tool electrode, the pulse voltage of the tool electrode is increased to obtain a larger processing aperture; but when the pulse voltage is increased, it is easy to break down the processing gap between the tool electrode and the workpiece, causing the inner wall of the workpiece to be processed and The tool electrode is directly short-circuited. After the short circuit, the tool electrode and the workpiece will be burned, resulting in the loss of the tool electrode and the workpiece, affecting the normal operation of the electrolysis and reducing ...

AI Technical Summary

Problems solved by technology

When the processing aperture of the tool electrode needs to be enlarged, the pulse voltage of the tool electrode is increased to obtain a larger processing aperture; however, when the pulse voltage is increased, it is easy to break down the processing gap between the tool electrode and the workpiece, causing the inner wall of the workpiece to be processed and The tool electrode is directly short-circuited. After the short circuit, the tool electrode and the workpiece will be burned, resulting in the loss of the tool electrode and the workpiece, affecting the normal operation of the electrolysis and reducing work efficiency; hole, or to process multiple deep holes with different diameters, such as fine nozzles, porous structures, etc., the processing efficiency of a single tool electrode is extremely low, and it is difficult to control the diameter change process when using multiple tool electrodes. Machining accuracy cannot be guaranteed
