Grinding (abrasive cutting) - Wikipedia

Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool.. A wide variety of machines are used for grinding: Hand-cranked knife-sharpening stones (grindstones)Handheld power tools such as angle grinders and die grinders; Various kinds of expensive industrial machine tools called grinding machines; Bench grinders

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 oils.
