Calibrating makes it possible to obtain a rough surface that is at the same time homogenous and flat: these are essential characteristics for the subsequent smoothing of ceramic and porcelain stoneware.

For many years Italdiamant has been producing cylindrical rollers and satellites for homogeneous, long lasting flattening: spiral rollers with 3, 5, 8, or 10 spirals, standard solution, or with the “Paccodisk” system for more cutting power, and metallic satellites with resin for perfect finishing.
