Embodiment

[0054] The machined part is a TC4 test block, and one side wall of the test block is removed by internal jet side milling electrolytic milling. The geometric size of the test block is 30 mm × 30 mm × 100 mm, the electrode size is 20 mm in diameter, and the side wall has 6 narrow slit liquid ejection ports, the slit width is 1 mm and the length is 21 mm.

[0055] Install the inner jet milling head and inner cavity electrode according to the technical scheme. After the installation is completed, the parts are connected to the positive pole of the power supply, and the electrode is connected to the negative pole of the power supply. Electrolytic milling process parameters and power supply parameters are selected, a certain machining voltage is applied between the electrodes, the electrolyte is flushed from the machining gap at a high speed with a certain pressure, and the electrodes are fed at the same time until the machining is completed.

Abstract

The side milling type electrolytic milling electrode comprises a columnar body, blind holes, first threads and a liquid spraying opening, the blind holes, the first threads and the liquid spraying opening are formed in the columnar body, the blind holes penetrate through the columnar body in the axial direction, and the first threads are formed in the outer wall of the columnar body and used for being in threaded connection with an electrode connector; the multiple liquid spraying openings are sequentially formed in the outer wall of the columnar body at intervals in the axial direction, and each liquid spraying opening is communicated with the corresponding blind hole in a one-to-one mode. The electrolytic milling cutter head comprises a liquid collecting sleeve, a mounting seat and an inner liquid spraying shaft, the inner liquid spraying shaft is sleeved with the liquid collecting sleeve, and the liquid collecting sleeve and the inner liquid spraying shaft are both mounted on the machine tool spindle outer sleeve through the mounting seat. The side milling type electrolytic milling electrode aims at solving the problem that in the electrolytic milling machining process, due to the fact that the space of a non-machining area is open, electrolyte overflows and is lost.

Description

technical field [0001] The invention relates to the technical field of electrolytic milling, in particular to a side milling type electrolytic milling electrode and an electrolytic milling head. Background technique [0002] Electrolytic milling is a processing method that uses a rotary electrode as a cathode to dissolve and remove anode metal materials based on the principle of anode electrochemical dissolution. Electrolytic milling uses a high-speed rotating electrode to move according to a certain trajectory through the control of a numerical control system to realize the formation of complex surfaces. The electrode of side milling electrolytic milling is generally cylindrical, and the outer side of the cylinder is the electrolytic milling processing area to realize side milling. During electrolytic milling, the distribution of the electrolyte flow field in the cathode and anode gaps has an important influence on the material removal process. The electrolyte not only ac...
