Abstract

The invention provides a micro hole machining method and equipment and belongs to the technical field of specially machining micro holes. The two ends of a tube electrode and the two ends of a machining workpiece are connected with double power supplies including an electrical discharge machining power supply and an electrochemical machining power supply respectively; and electrolysis and electrical discharge composite controllable machining is realized by controlling machining parameters of the electrical discharge machining power supply and the electrochemical machining power supply. According to the micro hole machining method and equipment, a recast layer and a burr generated by singly electrical discharge machining the micro hole can be removed, and the efficiency and the machining accuracy when the micro hole is singly electrical discharge machined are improved; and better quality of the machined surface of the micro hole as well as higher machining efficiency and machining accuracy can be obtained.

Description

technical field [0001] The invention relates to a microhole processing method and equipment, and belongs to the technical field of special processing microholes. Background technique [0002] With the continuous innovation and deepening of micro-hole processing methods and equipment for high-performance materials, micro-hole processing has been greatly improved in terms of production and application. At present, for micro-hole machining methods such as EDM micro-hole method, the surface of micro-holes is processed to produce a recast layer, which affects the surface quality of micro-hole machining; the method of electrolytic machining of micro-holes, the surface quality of micro-holes is better, but the processing efficiency And the machining accuracy is relatively low. In order to avoid the generation of recast layer in micro hole processing, improve the efficiency and precision of micro hole processing, etc., it is necessary to improve the surface quality of micro hole pr...
