Michael Faraday 1791-1867

Old technology brought up to high-tech standard

The technology comprises elements of the sinker EDM but electrical current technique and work piece specific set-up tools are added factors.

Looking back: in 1832, Faraday established the principles of electrolysis, now known as Faraday's law of induction. Electrolysis is the separation of chemically bonded elements by passing an electric current through them. These laws are the foundation of electrochemical machining. The ECM principle was first applied in 1920 for the production of drills. A patent application for a working electrochemical sinker process was lodged as early as 1930. The process was applied in the aerospace industry for the first time in the 1950s.

PEMtec, an international machinery manufacturer, has been researching and developing Precise ECM metal working machinery since 1995. The company is amongst the leading manufacturers of the Precise ECM technique. To develop new markets, partnerships with qualified tool manufacturing companies have been forged which are represented as application centres.

The Gebr. Bräm Ltd company is the first such application centre and is responsible for the Swiss and Liechtenstein market as well as for some select clients abroad.
