POLINOX® fibre-backing discs, radial construction

POLINOX Fibre-backing discPOLINOX® grinding discs are made of non-woven polyamide abrasive, into which abrasive grain is integrated. The non-woven abrasive flaps are attached to a fiberglass backer, for face-down finishing work. Densely stacked flaps make the disc durable. The tool is designed for working on large surfaces with variable speed angle grinders.Special featuresConforms to contours due to high flexibility.Cool grinding and low thermal load on the workpiece.The open structure and high flexibility of the non-woven material prevents loading.ApplicationsCleaningDeburringStep-by-step fine grindingRougheningStructuring (matt finishing, brush matting and satin finishing)Surface workMaterials that can be workedStainless steel (INOX)Steel materials with a hardness > 54 HRCSteels up to 370 HV (< 38 HRC)ThermoplasticsTitaniumTitanium alloysZincAluminumBrassBronzeCast steelCobalt-based alloysCopperFibre-reinforced thermosetting plastics (GRP, CRP)Hardened, heat-treated steels over 370 HV (38 HRC)Nickel-based alloys (e.g. Inconell and Hastelloy)Recommendations for useFor the best performance, use with a recommended peripheral speed of 2,000-4,000 SFPM. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and flap wheel/cross buff wear.SafetyThe maximum permitted peripheral speed is 6,300 SFPM.For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.Technical informationDia.
