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. Coolants are applied by either flooding the work area or by ...

Surface grinding machine - SlideShare

The grinding operation is similar to that of face milling on a vertical milling machine. In this machine a cup shaped wheel grinds the work piece over its full width using end face of the wheel as shown in Fig b. This brings more grits in action at the same time and consequently a higher material removal rate may be attained than for grinding with a peripheral wheel.
