<p>The method making the cylinder (2) turn around its longitudinal axis (3) . Then removing the chromium covering (23) by contrast bodies (41) belonging to at least one first rotating disk (4). Finally smoothing the copper coat (22) down below the chromium covering, by at least a second rotating disk provided with abrasive elements. The removing of the chromium covering being determined by the breaking of the chromium covering which is obtained through the elastic collapsing of the down below copper coat (22) when the contrasting bodies (41) interfere against the chromium coat. The contrasting bodies are made of diamond granules which are fixed in the rotating disk by a bonding agent (42). A modular smoothing polishing machine is provided comprising a basement (202) which holds a support and a rotating group of a cylindrical body to be worked and a smoothing group (5) of the lateral surface of the cylindrical body.</p> |
