POLINOX® cross buffs

POLINOX® Cross Buff

POLINOX Cross BuffPOLINOX® cross buffs are made of non-woven polyamide abrasive, into which abrasive grain is integrated. The non-woven abrasive is staggered and stacked around a core and resembles a star. Ideal for hard-to-reach places like drilled holes and indentations. POLINOX® cross buffs are designed for cleaning, deburring and fine grinding of inner surfaces and contours.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.
