Is it true that the material removal is about 90% electrochemical and 10% abrasive?
The 90/10 electrochemical/abrasive rule is a myth. The ratio of electrochemical to abrasive cutting is widely variable by parameter settings. Cutting at 2 volts would give a predominately abrasive cut. However, if it produces the desired result it should be used. A proper and effective Electrochemical Grinding Equipment setup should focus on maintaining the correct balance of productivity, wheel wear, tolerance, surface finish and metallurgical condition.
