Method and apparatus for purging the eroding zone during electroerosive countersinking

摘要

Method and apparatus for purging the eroding zone during electroerosive countersinking, in which one or more short-stroke second raising lowering movements of a tool electrode relative to a workpiece are performed in the dielectric between two first long stroke raising/lowering movements and the frequency and/or height of stroke of the raising/lowering movements is automatically adapted to the conditions in the working gap.
