Electrochemical Machining is one of the most promising non traditional machining processes. It has been applied in automotive and aerospace industries. Nowadays, only a few manufacturer worldwide possess the technology for the manufacturing of electrochemical equipment. This being the case, the present work aims to the develop a prototype to be used in research. Prior to the project specification, it is presented an explanation on the nature of the electrochemical process. Alter detailing the project and building the prototype, the machine was tested for drilling high speed Steel and deburring rings of SC 3428 (DIN 1629) Steel. The holes were analysed considering not only the remove material rate but also the overcut and taper accuracy. With regard to deburring, it was analysed the machining time and the visual quality of the surface. Additionally, the findings are related to those presented in the literature and possible reasons for the differences found are discussed.
