Abstract
To regulate the flushing liquid medium in the cutting zone of a TW electroerosion apparatus an elongate element is introduced into the cutting slot formed behind the advancing wire electrode and is maintained immediately behind the wire electrode and in parallel therewith, and thus dams the flushing medium in the space between the wire electrode and the element while serving to hold the wire electrode against deflecting rearwards. The elongate element is advantageously a tube having one or more apertures formed in a lateral wall thereof juxtaposed with the wire electrode, through which apertures the cutting liquid medium is discharged into the cutting zone and/or the flushing liquid medium in the cutting zone is sucked to assure an equalized distribution in the rate of flow in the cutting zone across the thickness of the workpiece. During a course of the cutting operation, the elongate element may be axially moved or reciprocated, or laterally oscillated.
