Abstract

The prospects are shown in the combination of the processes of electro-chemical dilution and electro-erosion removal of material worked at pinholes broaching with a fixed cathode-tool. The procedure of high-voltage pulses formation for the parameter control of integrated working is presented. The source ensuring the formation of high-voltage pulses with voltage up to 400 V, duration of 4 mcs and a period from 12 to 50mcs is developed. The experimental plant has been developed for the integrated electro-erosion and electro-chemical broaching of pinholes at electrolyte supply under pressure through a fixed cathode-tool. It is shown that the introduction of an electro-erosion constituent in the course of working increased a broaching rate more than 10 times. The creation of channels of discharge on a gas-vapor jacket in a spark gap allows realizing current densities from 50…100 a/cm2 at the primary moment and up to 10…15 a/cm2 by the end of working. The limitations were established to ensure the accuracy of a hole formed and connected with the instability of the value of a spark gap. There is offered a way to increase a hole accuracy at the expense of the use of the working procedure with the stabilization of the value of a spark gap.
