Cold rolling is the most common method of work hardening. This involves the metal being passed through pairs of rollers to reduce its thickness or to make the thickness uniform. As it moves through the rollers and is compressed, the metal grains are deformed. Examples of coldrolled products include steel sheets, strips, bars, and rods.

The action of a hardened ball against a softer, flat plate illustrates the process of burnishing. If the ball is pushed directly into the plate, stresses develop in both objects around the area where they contact. As this normal force increases, both the ball and the plate''s surfaces deform. ... Roller burnishing, or surface rolling, is used on ...

Transversal rolling of balls from the round billet is economical. It differs from other methods due to the possibility to produce grinding balls on the uninterrupted automated aggregates, which allows 2 to 8 times to increase the output and 1015% to reduce the consumption of metal. The process involves the following stages:

The high pressure applied to the balls also induces cold working, which strengthens the balls. Sometimes the balls are then run through a soft grinding process afterward to improve precision. This is done in the same type of machine, but the rill plates are replaced with grinding stones. If the balls are steel they are then heat treated.
