The continuous moving thin metal wire (called the electrode wire) is used as an electrode, and the workpiece is subjected to pulse spark discharge to remove metal and cut. It is mainly used to machine a variety of complex and precise workpieces. In the process of slow wire cutting, the cutting is mainly done in water, so the requirements for water quality are relatively high. Suzhou Bojie resin provides EDM resin, high effluent resin, long and stable life cycle, and the effluent can reach more than 15 megaohms.
