Difference Between Machining and Grinding
Machining Grinding Machining is one bulk material removal process (i.e. high MRR). Thus it is economical and suitable to give proper size and also for semifinishing. Grinding has low material removal rate and is preferred only for finishing. Accuracy and tolerance achieved by conventional machining

Basics of Grinding Manufacturing
grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding
