Sheet producers under pressure to produce flawless sheet for automotive and other demanding applications know that texture on work rolls is critical because it's transferred to the sheet being produced. Electro-Discharge Texturing (EDT) is a specialized texturing process that replaces shot blast and provides a superior surface texture on rolls prior to chroming. It produces consistent, repeatable surfaces with tight tolerances from 50-350 Ra, extremely uniform surface with little variance over the surface of the roll and superior textured surfaces on hard work rolls.
Using proprietary EDT equipment, designed and manufactured by SMS Modern Hard Chrome, we can uniformly texture the entire roll surface, with no gaps on the ends. And our EDT equipment also removes grind chatter while texturing to produce dependable rolls that consistently deliver quality sheet.
More information on electro-discharge roll texturing is available in the "Advanced Roll Maintenance for Increased Productivity" brochure on the "Literature downloads" page of this site.
