Electrochemical process where an electrolyte is pumped under pressure through the tool to cut a hole through rapid corrosion. Beskrivning The process By connecting it to a power source the workpiece acts as the anode and the tool as the cathode. A preheated electrolyte [1] is continuously supplied through the tool down to its tip where the workpiece is dissolved by accelerated corrosion resulting from electrochemical machining. The tool thus never touches the workpiece but there is always a gap with a liquid between them. This means that the processed contour is always slightly larger than the tool [2]. The tool's sides are insulated [3] to prevent the bore sides from continuing to be corroded. Over time the processed hole becomes deeper. Electrochemical drilling Process films
