Cylindrical grinding
Cylindrical grinding
The 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. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft.
Cylindrical grinding is define d as having four essential actions:
1. The work (object) musst be constantly rotating
2. The grinding wheel m ust be constantly rotating
3. The grinding wheel is fed towards and away from the work
4. Either the work or the grinding wheel is traversed with respect to th e other.
While the majority of cylindri cal grinders employ all four movements, there are grinders that only employ three of the four actions.
There are five different types of cylindrical grinding: outside diameter (O D) grinding, inside diameter (ID) grinding, plunge grinding, creep feed grinding, and centerles s grinding.

Grinding Wheels
A grinding wheel is an expendable
wheel that is composed of an abrasive compound used for various grinding
(abrasive cutting) and abrasive machining operations. They are used in grinding
machines.
The wheels are generally made from a matrix of coarse particles pressed and bonded together to form a solid, circular shape. Various profiles and cross sections are available depending on the intended usage for the wheel. They may also be made from a solid steel or aluminium disc with particles bonded to the surface.
