SYSTEM FOR CONTROL OF FLUSHING FLOW IN A SPARK DISCHARGE (EDM) MACHINE

摘要

A control system for flushing fluid flow in an EDM machine provides independent control of flow characteristics at the upper and lower nozzle outlets (39). The control system operates in a flow control mode and a pressure control mode. In the pressure control mode, pressure transducers (144, 146) are utilized to provide a feed-back signal (Fig. 5).
