ECD

ECD (electro chemical drilling) is a technique that allows non-straight paths to be drilled in hard metals such as gas turbine components. It is an electrolytic process that is also called stem-drilling. The ECD principle works as follows: a product (anode) is hung in acid and a tool (cathode ) is placed. By applying a voltage difference, the particles of the work piece dissolve in the acid. The possibility of drilling holes is created by controlling the operation of this process. Based on many years of experience in ECD, Detechco developed its own advanced machine for this technique: the Techco 5.
