The PECM technology is a special method for deliberately controlling, dissolving and removing metal by way of an electrochemical process. In a conductive electrolyte (salt water), a positively charged workpiece (anode) takes on the shape of the negatively charged tool electrode (cathode) with the help of a controlled pulse current. The PECM process thus represents a refinement of electrochemical machining. Using a precise pulse current and an oscillating tool electrode enables us to create the basis for a very small processing gap. This allows for high-precision and economic manufacturing without process-related tool wear. Workpieces can be created with a reproduction accuracy and reproducibility of 2-5 μm in an absolutely contactless fashion, all without chemical agents or mechanical forces.
