Abstract

The invention relates to an electric spark micropore machining device and an electric spark micropore machining method. The electric spark micropore machining device comprises a shell, a ceramic nozzle and a workpiece fixing piece. The shell is provided with a cavity, and the cavity is used for bearing an electrode wire. The shell is further provided with a vent hole, the vent hole communicates with the cavity, and the vent hole is used for introducing gas into the cavity. The ceramic nozzle is connected with one end of the shell, the ceramic nozzle and the shell are coaxially arranged, the opening size of the ceramic nozzle is decreased in the direction away from the shell, and the ceramic nozzle can allow the electrode wire to penetrate through. The workpiece fixing piece is used for fixing a workpiece, so that the plane where the bottom of the workpiece is located is perpendicular to the axial direction of the shell and the ceramic nozzle. The electric spark micropore machining device can control the size precision of the workpiece electrode and reduce the perpendicularity error between the electrode wire and the workpiece plane.

Description

technical field [0001] The invention relates to the field of microhole machining, in particular to an electric discharge microhole machining device and an electric discharge microhole machining method. Background technique [0002] With the development of product components in the direction of precision and miniaturization, micropores (aperture <0.1mm) have been widely developed in the fields of aerospace, precision instruments and automobile manufacturing with their unique functional structures, such as in the air duct of high-pressure compressors of aeroengines. Damping bushings for high-pressure turbines, front axle damping cylinders and rear axle damping rings, electron microscope apertures, chemical fiber spinnerets, and automotive engine fuel injectors, etc. As an important part of micro-machining, micro-EDM technology with non-contact, no obvious macroscopic force, and softness over rigidity has been widely used in micro-hole machining of difficult-to-machine mater...
