ID grinding is grinding occurring on the inside of an object. The
grinding wheel is always smaller than the width of the hole being
ground. The object is held in place by a collet which also rotates the object in place. Just as with OD grinding, the grinding wheel and the object rotated in opposite directions giving reversed direction contact of the two surfaces where the grinding occur.
The Okuma cylindrical grinder is a type of grinding machine used
to shape the outside of an object. The cylindrical grinder can work on a
variety of shapes, however the object must have a central axis of rotation.
The cylindrical grinder is responsible for a plethora of innovations and inventions in the progression of science and technology. And situation in which extremely precise metalworking is required, the cylindrical grinder is able to provide a high level of precision. From the automotive industry to military applications, the benefits of the cylindrical grinder are numerous.
