Precise Electrochemical Machining (PEM) is a powerful, non-contact metal shaping process that pairs a PEM Machine with an electrolyte processing unit, power generator, and operator control station. Using electric current and an oscillating tool bathed in a conductive electrolyte (salt water), PEM dissolves metal by liquefication. A positively charged workpiece (the anode) takes the form of the negatively charged tool (the cathode) as the metal is dissolved. The result is a high quality, burr-free part.
