Abstract

The invention discloses a complex-surface recast-layer-free single/group-hole multi-station electric spark-electrolytic machine tool which comprises a machine tool body, a cathode system, a working solution circulating system, a power system and a control system. A control circuit of the power system controls switching among different-waveform power supplies according to different machining requirements, a power signal is applied to tool electrodes and a workpiece power supply system via an output circuit, and a single-loop or multi-loop power supply mode is adopted to independently supply power to the tool electrodes. A working solution circulation switching device can meet special requirements on free switching of internal and external solution flushing of tube electrodes for electric spark-electrolytic combined machining, and high-low pressure solution flushing and intermittent solution flushing can be realized; a clamping system of the cathode system can clamp single or multiple tool electrodes to realize single-hole and group-hole multi-station synchronous machining. The machine tool can realize electric spark-electrolytic combined hole-forming machining, and is simple in mechanism, high in machining efficiency and wide in application range; machined hole walls have no defects such as recast layers and micro cracks.

Description

technical field [0001] The invention relates to a single / group hole multi-station electric spark-electrolytic machining machine tool with complex curved surface without recasting layer, which belongs to the field of special processing equipment. Background technique [0002] In aerospace, electrical and electronics, instrumentation, light industry and textile and other industrial fields, there are more and more small single / group hole structure parts, and the number of holes in the parts is getting larger and smaller, and the diameter is getting smaller and smaller. The requirements for precision and surface quality are getting higher and higher. However, industrial parts have a wide variety of materials, complex structures, and difficult processing. Especially in the field of aerospace and military industry, due to the special environmental conditions of equipment work, the materials are often required to have high hardness and strength, good heat resistance and corrosion r...
