EDT involves taking a pre-ground roll with a known diameter and shape profile . a means of texturing mill work rolls in order to imprint a microscopic roughness. Jewelry Design with Found Objects Tickets, Sat, Jun 3, 2017 at 10 .
Using EDT instead of other traditional texturing methods gives us greater precision and control over the final product. Rockport Roll Shop's EDT process produces improved consistency from roll to roll, higher peak count, lower waviness, and better strip control. It also reduces the influence of roll hardness on the final roughness of the roll.
· 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 ...
