Abstract
The method of preparing cold mill work rolls for forming a surface finish on a metal substrate includes the steps of placing a work roll on a grinder, truing the work roll, roughening the work roll, and performing at least one finishing pass on the work roll. The method may further include the step of sanding the work roll. The finished work roll may be inserted into a cold mill and the metal substrate cold rolled with the work rolls to achieve the desired surface finish.
