FIELD: technological processes.
SUBSTANCE: invention relates to the field of rolling. Textured working roll is configured to impart a metal substrate, such as a sheet of aluminum or an aluminum alloy, to a given texture. Textured working roll can be used for gloss finishing of the metal base. Exclusion of probability of cracks formation on rolled sheet is provided due to that roller can be textured by grinding of working roll to obtain ground working roll, electrosparking texturing of working roll to produce electrosparked textured working roll and to polish working roll to produce polished working roll. Polished working roll has Ra value between 0.30 mcm and 0.70 mcm.
EFFECT: textured working roll for metal base is proposed.
