Flap Disc, PVL-R, POLIVLIES® CURVE

Flap Disc, PVL-R, POLIVLIES CURVEEngineered for maximum operational efficiency, the PFERD PVL-R POLIVLIES® CURVE Flap Disc delivers superior surface conditioning and material removal performance. Featuring a coarse-grade aluminum oxide abrasive, this disc is optimized for aggressive stock removal while maintaining consistent surface integrity across ferrous and non-ferrous metals. Constructed with a high-performance abrasive non-woven material, the flap design continuously exposes fresh, sharp abrasive grains during use, ensuring uniform surface quality and extended service life. The CURVE profile allows for edge grinding and contour following, making it ideal for applications requiring precision on irregular geometries and hard-to-reach surfaces.Special featuresCost-effective due to high abrasive performance and durability.Creates a consistently high surface quality throughout the entire service life, as new sharp abrasive material is constantly exposed.Conforms to contours due to high flexibility.ApplicationsCleaningDeburringStep-by-step fine grindingRougheningStructuring (matt finishing, brush matting and satin finishing)Surface workWork on weld seamsMaterials 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 6,000-7,000 SFPM.SafetyFor safety reasons, the maximum permitted rotational speed indicated must never be exceeded.Technical informationVersioncoarseDia.
