Question:-
Consider the following statements:
In electrochemical grinding,
1. a rubber bonded alumina grinding wheel acts as the cathode and the workpiece as the anode
2. a copper bonded alumina grinding wheel acts as the cathode and the workpiece as the anode
3. metal removal takes place due to the pressure applied by the grinding wheel
4. metal removal takes place due to electrolysis
Which of these statements are correct?
Option (A)
1 and 3
Option (B)
2 and 4
Option(C)
2 and 3
Option(D)
1 and 4
Correct Option:
(B)
Question Solution:
In the electrochemical grinding, a copper bonded alumina grinding wheel act as cathode and work piece as anode.
The material removal rate take places due to
90% chemical action
10% mechanical action
