Italdiamant’s diamond tools for calibrating engineered stone and quartz arose from a combination of an in-depth knowledge of production cycles and keeping track of our clients’ evolving needs. Calibration is not only the first step in working with these materials, but it is also fundamental. Slabs are calibrated on both sides so as to eliminate moulding defects, and to prepare materials for subsequent steps. Cylindrical, spiral and “Paccodisc” spiral rollers, as well as calibrating plates, have been designed to obtain maximum finishing efficiency and quality, and also to aid in keeping stress on transmission systems to an absolute minimum.
