CS260028B1 - Method of electro-erosion polishing - Google Patents

Abstract

The solution concerns electro-erosion treatment and is intended for polishing parts preliminarily electrically erosive. The aim is to reduce the polishing time of large ones surface evenly polished surface. In the EDM polishing using pulsed electric, arc with one polarity connected The electrodes according to the invention are carried out in intermittent conditions the same-directional arc, being medium fcodňota current limited by size, ensuring the time of existence of the arc is smaller one microsecond, taking to the electrodes a voltage of 300 to 800 V is connected.

Claims (2)

OBJECT OF THE INVENTION -k- 1, an electroerosive polishing method, "using a pulsed electric arc of the same polarity of the connected electrodes, characterized in that, in order to reduce the polishing time of large surfaces while providing a uniformly polished surface, the process is conducted under arc-direct arc interruption conditions, wherein the mean current is limited to a magnitude providing an arc time less than one microsecond, with a voltage of 300 to 800 volts attached to the electrodes. 2. Method according to claim 1, characterized in that the self-interrupted arc is intermittently interrupted at a frequency which, in the extreme, is ten times less than the automatic interruption frequency.
