The roll grinding process is a special form of external cylindrical grinding between centres the only difference being that the rolls being machined have much larger dimensions than conventional workpieces. The rolls are subjected to continuous wear in both hot and cold rolling mills and must be replaced and reworked at regular intervals.
Grinding taper end relief on roll covers. Mark the length of taper on the roll ends. Increase the RPMs on the roll, carefully to a safe speed. Reduce the traverse speed as low as possible. Always start a taper on the face of the roll and traverse outward off the face. Turn the infeed slowly as the grinding wheel moves to the end of the roll.

The process of generating a new surface and removing material for high precision rolls is called roll grinding. Compared to other process such as milling or turning, the desired surface finish and precision can be obtained much more effectively through grinding a precision roll.
2002-9-1ensp0183enspThe purpose was to detect the main dynamical characteristics of the grinding system by such simplified equations. To investigate the dynamics of this roll grinding process in detail, the roll is considered as a rotor dynamical system with appropriate equations of motion. The theory of rotor dynamics is discussed e.g., , .
2020-10-18ensp0183enspGrinding 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.
