Fig. 4 schematically shows an electrochemical drilling unit. Power supply: During ECM, a high value of direct current ( may be as high as 40000 A) and a low value of electric potential ( in range of 5-25 V) across IEG( Interelectrode gap) is desirable. The highest current density achieved so far is around 20,000 A/cm 2. Hence, with the help of a rectifier and a transformer, three phase AC is ...

1 Surface Finishes Can Be Achieved With Electrochemical Grinding (Ecg) The Electrochemical Grinding (ECG) process does not leave the typical shiny finish of abrasive grinding. This is because there is no smearing of the metal as in conventional grinding. A 16 micro inch finish or better can be achieved but it will have a matte (dull) rather than a polished look. 2.

Electrochemical grinding - Wikipedia

Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour ...

Accuracies achieved by ECG are usually about 0.125 millimeter. A drawback of ECG is the loss of accuracy when inside corners are ground. Because of the electric field effects, radii better than 0.25 – 0.375 millimeter can seldom be achieved. A wide application of electrochemical grinding is the production of tungsten carbide cutting tools.
