ABSTRACT:
An electric discharge machine includes a clean work fluid tank for storing a clean work fluid and a work tank connected to the clean work fluid tank for receiving and storing the work fluid. An electric discharge is designed to occur through a small space between two charged electrodes, which are a workpiece and a tool, so that at each discharge a small amount of workpiece material is removed, producing particles which are suspended in the work fluid. A settling tank is connected to the work tank that receives and stores the work fluid and a filter container containing a ceramic filter is connected between the clean work fluid tank and the settling tank, so that the work fluid which is supplied from the settling tank passes through the ceramic filter and so that work fluid which has not been filtered is sent back to the settling tank.
