Abstract

The invention discloses a special-purpose high-frequency pulse power supply for an ultrafine micro electric discharge machine tool, which mainly includes two modules, namely a main control module and a high-frequency discharge module. Its power supply discharge voltage and discharge gap are multi-level adjustable, and the two can be combined at will. The invention can adapt to discharge machining of different materials, processing sizes and precisions, and can conveniently expand the pulse power supply to multi-pulse output, so as to adapt to various types of ultra-fine electric discharge processing machine tools.

Description

technical field [0001] The invention relates to the field of high-frequency pulse power supply, in particular to a high-frequency pulse power supply specially used for ultra-fine electric spark machining machine tools. Background technique [0002] EDM is to connect the tool electrode and the workpiece to the two poles of the pulse power supply respectively, and immerse them in the working fluid, and use the electrical corrosion phenomenon during the pulsed spark discharge between the positive and negative electrodes to erode the excess metal, and change the size and shape of the parts. And the special processing method that the surface quality is processed to the predetermined requirements. [0003] The voltage, pulse frequency and pulse width interval of the existing high-frequency pulse power supply used for EDM are not adjustable during pulsed spark discharge. Due to the diversity of workpiece materials, processing dimensions and precision requirements in actual process...
