Problems solved by technology

However, it is more difficult to manufacture electrodes with microstructure flutes; the method of lateral flushing is likely to cause electrode vibration, so the flushing speed is limited and the processing depth is still limited; the repetitive feeding caused by electrode retraction will reduce Machining accuracy; the method of electrode eccentric trajectory movement is not suitable for processing micro-holes with small diameters; the method of high-pressure flushing of hollow electrodes is limited by the outer diameter of hollow electrodes, and is not suitable for processing micro-holes with small diameters
[0004] At present, it is still necessary to solve the problems of difficult discharge of electrolytic products and slow renewal of electrolyte in micro-electrolytic machining

Abstract

The invention discloses an axial flushing micro-electrolytic machining device and a machining method. Connect the upper end of the lead rod to the negative pole of the pulse power supply, and the anode of the workpiece to the positive pole of the pulse power supply, so that the machine tool drives the axial flushing tool head close to the anode of the workpiece, and there is a machining gap between the working end of the tool electrode and the surface of the anode of the workpiece. The pressure of the pressure pump makes the electrolyte flush to the workpiece anode machined surface along the axial direction of the tool electrode, so that electrolysis occurs between the tool electrode and the workpiece anode machined surface until fine features are obtained on the workpiece anode machined surface. The processing method and processing device can effectively promote the discharge of electrolysis products and heat in the processing gap, accelerate the renewal of the electrolyte, and at the same time avoid the deformation and vibration of the fine tool electrode caused by the non-axial flushing. The axial flushing micro-electrochemical processing device and processing method of the present invention can realize efficient processing of micro-structure features with small size and large aspect ratio.
