Dec 08, 2016· Driven by a slight angle applied to the regulating wheel relative to the grinding wheel, the method basically "squeezes" the workpiece across the grinding wheel and out the other side. Infeed grinding — also called plunge grinding — is used to grind cylindrical parts with notches or complex shapes, such as gear shafts.
Inside diameter grinding, also called as internal grinding, is used for grinding the inner diameter of tubular object. Workpiece or object will have already drilled hole and internal grinding process will be performed to finish the inner surface of workpiece with the help of small grinding wheel rotating at higher revolution per minute.

The act of grinding can be deceivingly simple. But the devil''s in the details. Effective grinding requires operators to apply enough pressure at the correct angle to let the grains—the "cutting tool" of a grinding disc—remove the most metal in the shortest time, while not prematurely wearing the disc or burning out the grinding tool.
