In ECG, generally the direction of wheel rotation is opposite to the direction of feed of workpiece. The contact area between wheel and workpiece is larger in EC face grinding process, hence it is a faster process. As the contact area is less, EC cylindrical grinding is a slower process. Typical values of ECG operating parameters are given as ...
