Abstract

The invention provides a machining device and method for synchronizing piezoelectric ceramic vibration and electrochemistry discharging and belongs to the field of special composite machining. When anelectrochemistry power source outputs pulse currents, a piezoelectric ceramic power source outputs forward voltage excitation signals synchronously, piezoelectric ceramic is bent upwards, and a gap between a workpiece and a tool electrode becomes smaller; during pulse intermittence of the electrochemistry power source, when no glass workpiece is subjected to discharging machining, the piezoelectric ceramic power source outputs negative voltage excitation signals, the piezoelectric ceramic is bent downwards, and the gap between the workpiece and the tool electrode becomes large. The electrochemistry power source and the piezoelectric ceramic power source carry out discharging synchronously to enable the machining gap during the discharging stage to be reduced, the utilization efficiency ofthe discharging energy is improved, and the machining locality is enhanced; and during discharging stop intermittence, the machining gap becomes large, which is beneficial for throwing out corrosiveimpurities and updating electrolyte.

Description

technical field [0001] The invention relates to the field of composite micromachining in special processing technology, in particular to a processing device and method for synchronizing vibration and electrochemical discharge of piezoelectric ceramics, which is suitable for microfabrication and manufacture of insulating hard and brittle materials. Background technique [0002] Insulating hard and brittle materials represented by glass have excellent properties such as high hardness, chemical corrosion resistance, transparency and good biocompatibility. They are used in micro-accelerators, micro-reactors, micro-pumps, medical devices and optical systems in MEMS There are more and more applications. However, due to their hardness and brittleness, the processing technology is poor, precision micro-processing is more difficult, simple laser processing is prone to cracks, and the efficiency of electrochemical discharge processing is low. [0003] The laser electrochemical compos...
