Poliflex fine grinding tools are manufactured with high shape accuracy, outstandingly consistent quality and tight dimensional tolerances. They are ideally suited to fine grinding, structuring and preparations for polishing work, and are very frequently used for tool and mould-making applications. For fine face-down grinding on large surfaces. Poliflex fine grinding tools with the PUR bond are manufactured with green silicon carbide (SiC). The PUR bond is a very soft bond which is available in two hardness grades (PUR-W, PUR-MH). It is homogeneously interspersed with abrasive grain.
