ABSTRACT:
Stainless steel belts having a thickness of about 0.060 inch used for casting sheet materials such as acrylic plastic sheet are refurbished by first grinding the back surface of the belt until no further distortions can be removed and then grinding the mirrored surface of the belt until said mirrored surface is uniformly dull and thereafter polishing the dulled surface to a mirrored finish. During the grinding and polishing, the belt is cooled to avoid local overheating.
