An electrosparking head device (10) is used in the electrosparking method and comprises a lower rack (3), an upper rack (6) and an inner rack (1), the upper rack (6) is positioned above the lower rack (3), and the inner rack (1) is positioned in a cavity formed by the lower rack (3) and the upper rack (6) and can slide up and down.

Description

technical field [0001] The invention relates to the field of electrical discharge machining, in particular to an electrical discharge machining method. Background technique [0002] EDM is a special processing method that uses the electric erosion effect generated by the pulse discharge between the two electrodes immersed in the working fluid to erode conductive materials, also known as electric discharge machining or electric erosion machining. [0003] During EDM, the tool electrode and the workpiece are respectively connected to the two poles of the pulse power supply, and immersed in the working fluid, or the working fluid is filled into the discharge gap. The tool electrode is controlled to feed to the workpiece through the gap automatic control system. When the gap between the two electrodes reaches a certain distance, the pulse voltage applied to the two electrodes will break down the working fluid and generate spark discharge. A large amount of heat energy is concen...
