Electro-chemical machining – great precision and highly cost-effective
The electro-chemical machining process is based on the principle of electrolysis. An electrode is connected to a D.C. source to act as a cathode (tool). The workpiece represents the other electrode and is poled as anode. In a watery electrolyte solution cathode and workpiece exchange a charge that machines the workpiece at the selected point, generating contours, annular grooves, flutes or cavities of the highest precision, without touching. The material being removed separates from the electrolyte solution as metal hydroxide.Machining takes place irrespective of the microstructure of the metal. Both soft and hard materials can be machined. The components are exposed to neither thermal nor mechanical stresses.
