O (D) None of the above​

Answer 1

Which is CORRECT statement about electro-chemical grinding operation?

O (B) Very hard materials can be ground precisely

Answer 2

Answer:

Correct Option:(B)

Explanation:

The electro-chemical grinding operation can manage the hard material very easily.During the Electro-Chemical Grinding/ECG process, metal shearing is made possible by the effects of abrasive particles and electrochemical dissolution. In electro-chemical grinding method, about 90% of the metal that is cut from the work piece is cut by chemical dissolution, and the rest of the metal is cut by abrasive particles.The electrochemical abrasive method is similar to the normal abrasive process. In electrochemical abrasive method, an abrasive wheel is used in which the workpiece is set. About 10% of the machining on the workpiece by abrasive wheel is done by this method and the rest by electrochemical dissolution.
