Cylindrical Grinding is a process where you use a grinding wheel rotating in a horizontal axis to cut or grind a cylindrical work-piece mounted on a chuck or between centers rotating in an axis parallel to the grinding wheel axis, in the same plane. Abrasive particles on the grinding wheel do the cutting of material.
Ball hardness is in the 60–67 HRC range. They wear better than 440C stainless steel and through-hardened carbon steel. They are also recommended for applications where a through-hardened steel ball is needed in larger sizes (½" and larger). They are sometimes packaged with a very light oil finish to reduce rust due to humidity. (SAE 52100)

Heavy-Removal Grinding Wheelsfor Angle Grinders— Use on Metals. A large grinding surface, combined with a thick layer of rough abrasive removes more material than other wheels. They are also known as Type 11 wheels, flared-cup wheels, snagging wheels, and cup stones.
A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
2.1 Machining ball rolling elements. In the grinding process of balls, the balls are placed on a cast iron plate with grooves parallel to the grinding wheel. The process takes place over several stages which can be grouped into two overarching phases: rough grinding and finish or lapping operations. 2.1.1 Rough grinding.
