The electrochemical grinding process is a highly specialized method that combines surface grinding, chemistry, and fixturing, and has limited applications. OD grinding is used to shape the external surface of objects between the centers and excels at removing circular defects and restoring or creating roundness.
In this paper, the electrochemical grinding process removes most of the material by electrochemical machining, and a brittle passivation film is formed on the surface of the material. The diamond abrasives attached to the ball-end scrape the passivation film away by the rotation of the spindle, and a new passivation film is produced on the ...

NC electrochemical mechanical drilling was based on NC, Electrochemical machining and mechanical grinding. It drilled with different diameter composite cathodes. This kind of drilling method took the advantages of electrochemical mechanical, so it was not restricted by parts' strength, hardness and stiffness. The cover of cathode ensured the drilling precision.

Electrochemical Machining (ECM) is a non-traditional machining (NTM) process belonging to Electrochemical category. ECM is opposite of electrochemical or galvanic coating or deposition process. Thus ECM can be thought of a controlled anodic dissolution at atomic level of the work piece that is electrically conductive by a

Electrochemical Machining (ECM) is a non- traditional machining process belonging to electrochemical category. ECM is opposite of electrochemical or galvanic coating or deposition process. ECM is the controlled removal of metal by anodic dissolution in an electrolytic cell in which the workpiece is the anode and the tool is cathode.
grinding produces good surface finish and low values of tolerances but the machined parts are associated with burrs, heat affected zone and residual stresses. However, electrochemically machined components do not have such defects. Hence, a hybrid process called electrochemical grinding (ECG) has been developed.
