Apparatus for the preparation of machining liquid for an electroerosion machine

摘要

An apparatus for preparing a machining liquid of an electroerosion machine comprises a filter, to which is supplied concentrate flow from a concentrate tank and from which is drained a permeate flow. In order to obtain a high machining liquid quality the filter is constituted by a membrane filter, which is backflushed with a backflushing frequency, which is a function of a parameter of the electroerosion process.
