    A small roll diameter is advantageous because less roll is in contact with the material which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness which is overcome using backup rolls. These backup rolls are larger and contact the back side of the smaller rolls. Grinding represents a process that is done on the grinding machine where the roll surface is brought into an optimal condition by fine stock removal of roll material measured in micrones (value of roughness and stock removal).. Grinding operations prevent later splashing and popping of chrome layer from the roll surface which can result as a chrome peeling.
